-To access protected API endpoints, you need to include a JSON Web Token (JWT) in the `Authorization` header of your requests.
+To access protected API endpoints, you need to include a user-generated API key in the `X-API-KEY` header of your requests.
 
-## Obtaining a JWT
+## 1. Creating an API Key
 
-First, you need to authenticate with the `/api/v1/auth/login` endpoint by providing your email and password. If the credentials are correct, the API will return an `accessToken`.
+You can create, manage, and view your API keys through the application's user interface.
 
-**Request:**
+1.  Navigate to **Settings > API Keys** in the dashboard.
+2.  Click the **"Generate API Key"** button.
+3.  Provide a descriptive name for your key and select an expiration period.
+4.  The new API key will be displayed. **Copy this key immediately and store it in a secure location. You will not be able to see it again.**
 
-```http
-POST /api/v1/auth/login

+# Jobs API
+
+The Jobs API provides endpoints for monitoring the job queues and the jobs within them.
+
+## Overview
+
+Open Archiver uses a job queue system to handle asynchronous tasks like email ingestion and indexing. The system is built on Redis and BullMQ and uses a producer-consumer pattern.
+
+### Job Statuses
+
+Jobs can have one of the following statuses:
+
+- **active:** The job is currently being processed.
+- **completed:** The job has been completed successfully.
+- **failed:** The job has failed after all retry attempts.
+- **delayed:** The job is delayed and will be processed at a later time.
+- **waiting:** The job is waiting to be processed.
+- **paused:** The job is paused and will not be processed until it is resumed.
+
+### Errors
+
+When a job fails, the `failedReason` and `stacktrace` fields will contain information about the error. The `error` field will also be populated with the `failedReason` for easier access.
+
+### Job Preservation
+
+Jobs are preserved for a limited time after they are completed or failed. This means that the job counts and the jobs that you see in the API are for a limited time.
+
+- **Completed jobs:** The last 1000 completed jobs are preserved.
+- **Failed jobs:** The last 5000 failed jobs are preserved.
+
+## Get All Queues
+
+- **Endpoint:** `GET /v1/jobs/queues`
+- **Description:** Retrieves a list of all job queues and their job counts.
+- **Permissions:** `manage:all`
+- **Responses:**
+    - `200 OK`: Returns a list of queue overviews.
+    - `401 Unauthorized`: If the user is not authenticated.
+    - `403 Forbidden`: If the user does not have the required permissions.
+
+### Response Body
+
+```json
+{
+	"queues": [
+		{
+			"name": "ingestion",
+			"counts": {
+				"active": 0,
+				"completed": 56,

+				"paused": 0
+			}
+		}
+	]
+}
+```
+
+## Get Queue Jobs
+
+- **Endpoint:** `GET /v1/jobs/queues/:queueName`
+- **Description:** Retrieves a list of jobs within a specific queue, with pagination and filtering by status.
+- **Permissions:** `manage:all`
+- **URL Parameters:**
+    - `queueName` (string, required): The name of the queue to retrieve jobs from.
+- **Query Parameters:**
+    - `status` (string, optional): The status of the jobs to retrieve. Can be one of `active`, `completed`, `failed`, `delayed`, `waiting`, `paused`. Defaults to `failed`.
+    - `page` (number, optional): The page number to retrieve. Defaults to `1`.
+    - `limit` (number, optional): The number of jobs to retrieve per page. Defaults to `10`.
+- **Responses:**
+    - `200 OK`: Returns a detailed view of the queue, including a paginated list of jobs.
+    - `401 Unauthorized`: If the user is not authenticated.
+    - `403 Forbidden`: If the user does not have the required permissions.
+    - `404 Not Found`: If the specified queue does not exist.

+# Rate Limiting
+
+The API implements rate limiting as a security measure to protect your instance from denial-of-service (DoS) and brute-force attacks. This is a crucial feature for maintaining the security and stability of the application.
+
+## How It Works
+
+The rate limiter restricts the number of requests an IP address can make within a specific time frame. These limits are configurable via environment variables to suit your security needs.
+
+By default, the limits are:
+
+- **100 requests** per **1 minute** per IP address.
+
+If this limit is exceeded, the API will respond with an HTTP `429 Too Many Requests` status code.
+
+### Response Body
+
+When an IP address is rate-limited, the API will return a JSON response with the following format:
+
+```json
+{
+	"status": 429,
+	"message": "Too many requests from this IP, please try again after 15 minutes"
+}
+```
+
+## Configuration
+
+You can customize the rate-limiting settings by setting the following environment variables in your `.env` file:
+
+- `RATE_LIMIT_WINDOW_MS`: The time window in milliseconds. Defaults to `60000` (1 minute).
+- `RATE_LIMIT_MAX_REQUESTS`: The maximum number of requests allowed per IP address within the time window. Defaults to `100`.
+
+## Handling Rate Limits
+
+If you are developing a client that interacts with the API, you should handle rate limiting gracefully:
+
+1.  **Check the Status Code**: Monitor for a `429` HTTP status code in responses.
+2.  **Implement a Retry Mechanism**: When you receive a `429` response, it is best practice to wait before retrying the request. Implementing an exponential backoff strategy is recommended.
+3.  **Check Headers**: The response will include the following standard headers to help you manage your request rate:
+    - `RateLimit-Limit`: The maximum number of requests allowed in the current window.
+    - `RateLimit-Remaining`: The number of requests you have left in the current window.
+    - `RateLimit-Reset`: The time when the rate limit window will reset, in UTC epoch seconds.
+
+## Excluded Endpoints
+
+Certain essential endpoints are excluded from rate limiting to ensure the application's UI remains responsive. These are:
+
+- `/auth/status`
+- `/settings/system`
+
+These endpoints can be called as needed without affecting your rate limit count.

+# Audit Log: Backend Implementation
+
+The backend implementation of the audit log is handled by the `AuditService`, located in `packages/backend/src/services/AuditService.ts`. This service encapsulates all the logic for creating, retrieving, and verifying audit log entries.
+
+## Hashing and Verification Logic
+
+The core of the audit log's immutability lies in its hashing and verification logic.
+
+### Hash Calculation
+
+The `calculateHash` method is responsible for generating a SHA-256 hash of a log entry. To ensure consistency, it performs the following steps:
+
+1.  **Canonical Object Creation:** It constructs a new object with a fixed property order, ensuring that the object's structure is always the same.
+2.  **Timestamp Normalization:** It converts the `timestamp` to milliseconds since the epoch (`getTime()`) to avoid any precision-related discrepancies between the application and the database.
+3.  **Canonical Stringification:** It uses a custom `canonicalStringify` function to create a JSON string representation of the object. This function sorts the object keys, ensuring that the output is always the same, regardless of the in-memory property order.
+4.  **Hash Generation:** It computes a SHA-256 hash of the canonical string.
+
+### Verification Process
+
+The `verifyAuditLog` method is designed to be highly scalable and efficient, even with millions of log entries. It processes the logs in manageable chunks (e.g., 1000 at a time) to avoid loading the entire table into memory.
+
+The verification process involves the following steps:
+
+1.  **Iterative Processing:** It fetches the logs in batches within a `while` loop.
+2.  **Chain Verification:** For each log entry, it compares the `previousHash` with the `currentHash` of the preceding log. If they do not match, the chain is broken, and the verification fails.
+3.  **Hash Recalculation:** It recalculates the hash of the current log entry using the same `calculateHash` method used during creation.
+4.  **Integrity Check:** It compares the recalculated hash with the `currentHash` stored in the database. If they do not match, the log entry has been tampered with, and the verification fails.
+
+## Service Integration
+
+The `AuditService` is integrated into the application through the `AuditLogModule` (`packages/enterprise/src/modules/audit-log/audit-log.module.ts`), which registers the API routes for the audit log feature. The service's `createAuditLog` method is called from various other services throughout the application to record significant events.

+# Audit Log: User Interface
+
+The audit log user interface provides a comprehensive view of all significant events that have occurred within the Open Archiver system. It is designed to be intuitive and user-friendly, allowing administrators to easily monitor and review system activity.
+
+## Viewing Audit Logs
+
+The main audit log page displays a table of log entries, with the following columns:
+
+- **Timestamp:** The date and time of the event.
+- **Actor:** The identifier of the user or system process that performed the action.
+- **IP Address:** The IP address from which the action was initiated.
+- **Action:** The type of action performed, displayed as a color-coded badge for easy identification.
+- **Target Type:** The type of resource that was affected.
+- **Target ID:** The unique identifier of the affected resource.
+- **Details:** A truncated preview of the event's details. The full JSON object is displayed in a pop-up card on hover.
+
+## Filtering and Sorting
+
+The table can be sorted by timestamp by clicking the "Timestamp" header. This allows you to view the logs in either chronological or reverse chronological order.
+

+## Verifying Log Integrity
+
+The "Verify Log Integrity" button allows you to initiate a verification process to check the integrity of the entire audit log chain. This process recalculates the hash of each log entry and compares it to the stored hash, ensuring that the cryptographic chain is unbroken and no entries have been tampered with.
+
+### Verification Responses
+
+- **Success:** A success notification is displayed, confirming that the audit log integrity has been verified successfully. This means that the log chain is complete and no entries have been tampered with.
+
+- **Failure:** An error notification is displayed, indicating that the audit log chain is broken or an entry has been tampered with. The notification will include the ID of the log entry where the issue was detected. There are two types of failures:
+    - **Audit log chain is broken:** This means that the `previousHash` of a log entry does not match the `currentHash` of the preceding entry. This indicates that one or more log entries may have been deleted or inserted into the chain.
+    - **Audit log entry is tampered!:** This means that the recalculated hash of a log entry does not match its stored `currentHash`. This indicates that the data within the log entry has been altered.

+# Audit Log
+
+The Audit Log is an enterprise-grade feature designed to provide a complete, immutable, and verifiable record of every significant action that occurs within the Open Archiver system. Its primary purpose is to ensure compliance with strict regulatory standards, such as the German GoBD, by establishing a tamper-proof chain of evidence for all activities.
+
+## Core Principles
+
+To fulfill its compliance and security functions, the audit log adheres to the following core principles:
+
+### 1. Immutability
+
+Every log entry is cryptographically chained to the previous one. Each new entry contains a SHA-256 hash of the preceding entry's hash, creating a verifiable chain. Any attempt to alter or delete a past entry would break this chain and be immediately detectable through the verification process.
+
+### 2. Completeness
+
+The system is designed to log every significant event without exception. This includes not only user-initiated actions (like logins, searches, and downloads) but also automated system processes, such as data ingestion and policy-based deletions.
+
+### 3. Attribution
+
+Each log entry is unambiguously linked to the actor that initiated the event. This could be a specific authenticated user, an external auditor, or an automated system process. The actor's identifier and source IP address are recorded to ensure full traceability.
+
+### 4. Clarity and Detail
+
+Log entries are structured to be detailed and human-readable, providing sufficient context for an auditor to understand the event without needing specialized system knowledge. This includes the action performed, the target resource affected, and a JSON object with specific, contextual details of the event.
+
+### 5. Verifiability
+
+The integrity of the entire audit log can be verified at any time. A dedicated process iterates through the logs from the beginning, recalculating the hash of each entry and comparing it to the stored hash, ensuring the cryptographic chain is unbroken and no entries have been tampered with.

+# OCR Service
+
+The OCR (Optical Character Recognition) and text extraction service is responsible for extracting plain text content from various file formats, such as PDFs, Office documents, and more. This is a crucial component for making email attachments searchable.
+
+## Overview
+
+The system employs a two-pronged approach for text extraction:
+
+1.  **Primary Extractor (Apache Tika)**: A powerful and versatile toolkit that can extract text from a wide variety of file formats. It is the recommended method for its superior performance and format support.
+2.  **Legacy Extractor**: A fallback mechanism that uses a combination of libraries (`pdf2json`, `mammoth`, `xlsx`) for common file types like PDF, DOCX, and XLSX. This is used when Apache Tika is not configured.
+
+The main logic resides in `packages/backend/src/helpers/textExtractor.ts`, which decides which extraction method to use based on the application's configuration.
+
+## Configuration
+
+To enable the primary text extraction method, you must configure the URL of an Apache Tika server instance in your environment variables.
+
+In your `.env` file, set the `TIKA_URL`:
+
+```env
+# .env.example
+
+# Apache Tika Integration
+# ONLY active if TIKA_URL is set
+TIKA_URL=http://tika:9998
+```
+
+If `TIKA_URL` is not set, the system will automatically fall back to the legacy extraction methods. The service performs a health check on startup to verify connectivity with the Tika server.
+
+## File Size Limits
+
+To prevent excessive memory usage and processing time, the service imposes a general size limit on files submitted for text extraction. Files larger than the configured limit will be skipped.
+
+- **With Apache Tika**: The maximum file size is **100MB**.
+- **With Legacy Fallback**: The maximum file size is **50MB**.
+
+## Supported File Formats
+
+The service's ability to extract text depends on whether it's using Apache Tika or the legacy fallback methods.
+
+### With Apache Tika
+
+When `TIKA_URL` is configured, the service can process a vast range of file formats. Apache Tika is designed for broad compatibility and supports hundreds of file types, including but not limited to:
+
+- Portable Document Format (PDF)
+- Microsoft Office formats (DOC, DOCX, PPT, PPTX, XLS, XLSX)
+- OpenDocument Formats (ODT, ODS, ODP)
+- Rich Text Format (RTF)
+- Plain Text (TXT, CSV, JSON, XML, HTML)
+- Image formats with OCR capabilities (PNG, JPEG, TIFF)
+- Archive formats (ZIP, TAR, GZ)
+- Email formats (EML, MSG)
+
+For a complete and up-to-date list, please refer to the official [Apache Tika documentation](https://tika.apache.org/3.2.3/formats.html).
+
+### With Legacy Fallback
+
+When Tika is not configured, text extraction is limited to the following formats:
+
+- `application/pdf` (PDF)
+- `application/vnd.openxmlformats-officedocument.wordprocessingml.document` (DOCX)
+- `application/vnd.openxmlformats-officedocument.spreadsheetml.sheet` (XLSX)
+- Plain text formats such as `text/*`, `application/json`, and `application/xml`.
+
+## Features of the Tika Integration (`OcrService`)
+
+The `OcrService` (`packages/backend/src/services/OcrService.ts`) provides several enhancements to make text extraction efficient and robust.
+
+### Caching
+
+To avoid redundant processing of the same file, the service implements a simple LRU (Least Recently Used) cache.
+
+- **Cache Key**: A SHA-256 hash of the file's buffer is used as the cache key.
+- **Functionality**: If a file with the same hash is processed again, the text content is served directly from the cache, saving significant processing time.
+- **Statistics**: The service keeps track of cache hits, misses, and the hit rate for performance monitoring.
+
+### Concurrency Management (Semaphore)
+
+Extracting text from large files can be resource-intensive. To prevent the Tika server from being overwhelmed by multiple requests for the _same file_ simultaneously (e.g., during a large import), a semaphore mechanism is used.
+
+- **Functionality**: If a request for a specific file (identified by its hash) is already in progress, any subsequent requests for the same file will wait for the first one to complete and then use its result.
+- **Benefit**: This deduplicates parallel processing efforts and reduces unnecessary load on the Tika server.
+
+### Health Check and DNS Fallback
+
+- **Availability Check**: The service includes a `checkTikaAvailability` method to verify that the Tika server is reachable and operational. This check is performed on application startup.
+- **DNS Fallback**: For convenience in Docker environments, if the Tika URL uses the hostname `tika` (e.g., `http://tika:9998`), the service will automatically attempt a fallback to `localhost` if the initial connection fails.
+
+## Legacy Fallback Methods
+
+When Tika is not available, the `extractTextLegacy` function in `textExtractor.ts` handles extraction for a limited set of MIME types:
+
+- `application/pdf`: Processed using `pdf2json`. Includes a 50MB size limit and a 5-second timeout to prevent memory issues.
+- `application/vnd.openxmlformats-officedocument.wordprocessingml.document` (DOCX): Processed using `mammoth`.
+- `application/vnd.openxmlformats-officedocument.spreadsheetml.sheet` (XLSX): Processed using `xlsx`.
+- Plain text formats (`text/*`, `application/json`, `application/xml`): Converted directly from the buffer.

+# Integrity Check
+
+Open Archiver allows you to verify the integrity of your archived emails and their attachments. This guide explains how the integrity check works and what the results mean.
+
+## How It Works
+
+When an email is archived, Open Archiver calculates a unique cryptographic signature (a SHA256 hash) for the email's raw `.eml` file and for each of its attachments. These signatures are stored in the database alongside the email's metadata.
+
+The integrity check feature recalculates these signatures for the stored files and compares them to the original signatures stored in the database. This process allows you to verify that the content of your archived emails has not been altered, corrupted, or tampered with since the moment they were archived.
+
+## The Integrity Report
+
+When you view an email in the Open Archiver interface, an integrity report is automatically generated and displayed. This report provides a clear, at-a-glance status for the email file and each of its attachments.
+
+### Statuses
+
+- **Valid (Green Badge):** A "Valid" status means that the current signature of the file matches the original signature stored in the database. This is the expected status and indicates that the file's integrity is intact.
+
+- **Invalid (Red Badge):** An "Invalid" status means that the current signature of the file does _not_ match the original signature. This indicates that the file's content has changed since it was archived.
+
+### Reasons for an "Invalid" Status
+
+If a file is marked as "Invalid," you can hover over the badge to see a reason for the failure. Common reasons include:
+
+- **Stored hash does not match current hash:** This is the most common reason and indicates that the file's content has been modified. This could be due to accidental changes, data corruption, or unauthorized tampering.
+
+- **Could not read attachment file from storage:** This message indicates that the file could not be read from its storage location. This could be due to a storage system issue, a file permission problem, or because the file has been deleted.
+
+## What to Do If an Integrity Check Fails
+
+If you encounter an "Invalid" status for an email or attachment, it is important to investigate the issue. Here are some steps you can take:
+
+1.  **Check Storage:** Verify that the file exists in its storage location and that its permissions are correct.
+2.  **Review Audit Logs:** If you have audit logging enabled, review the logs for any unauthorized access or modifications to the file.
+3.  **Restore from Backup:** If you suspect data corruption, you may need to restore the affected file from a backup.
+
+The integrity check feature is a crucial tool for ensuring the long-term reliability and trustworthiness of your email archive. By regularly monitoring the integrity of your archived data, you can be confident that your records are accurate and complete.

+# Troubleshooting CORS Errors
+
+Cross-Origin Resource Sharing (CORS) is a security feature that controls how web applications in one domain can request and interact with resources in another. If not configured correctly, you may encounter errors when performing actions like uploading files.
+
+This guide will help you diagnose and resolve common CORS-related issues.
+
+## Symptoms
+
+You may be experiencing a CORS issue if you see one of the following errors in your browser's developer console or in the application's logs:
+
+- `TypeError: fetch failed`
+- `Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource.`
+- `Unexpected token 'C', "Cross-site"... is not valid JSON`
+- A JSON error response similar to the following:
+    ```json
+    {
+    	"message": "CORS Error: This origin is not allowed.",
+    	"requiredOrigin": "http://localhost:3000",
+    	"receivedOrigin": "https://localhost:3000"
+    }
+    ```
+
+## Root Cause
+
+These errors typically occur when the URL you are using to access the application in your browser does not exactly match the `APP_URL` configured in your `.env` file.
+
+This can happen for several reasons:
+
+- You are accessing the application via a different port.
+- You are using a reverse proxy that changes the protocol (e.g., from `http` to `https`).
+- The SvelteKit server, in a production build, is incorrectly guessing its public-facing URL.
+
+## Solution
+
+The solution is to ensure that the application's frontend and backend are correctly configured with the public-facing URL of your instance. This is done by setting two environment variables: `APP_URL` and `ORIGIN`.
+
+1.  **Open your `.env` file** in a text editor.
+
+2.  **Set `APP_URL`**: Define the `APP_URL` variable with the exact URL you use to access the application in your browser.
+
+    ```env
+    APP_URL=http://your-domain-or-ip:3000
+    ```
+
+3.  **Set `ORIGIN`**: The SvelteKit server requires a specific `ORIGIN` variable to correctly identify itself. This should always be set to the value of your `APP_URL`.
+
+    ```env
+    ORIGIN=$APP_URL
+    ```
+
+    By using `$APP_URL`, you ensure that both variables are always in sync.
+
+### Example Configuration
+
+If you are running the application locally on port `3000`, your configuration should look like this:
+
+```env
+APP_URL=http://localhost:3000
+ORIGIN=$APP_URL
+```
+
+If your application is behind a reverse proxy and is accessible at `https://archive.mycompany.com`, your configuration should be:
+
+```env
+APP_URL=https://archive.mycompany.com
+ORIGIN=$APP_URL
+```
+
+After making these changes to your `.env` file, you must restart the application for them to take effect:
+
+```bash
+docker compose up -d --force-recreate
+```
+
+This will ensure that the backend's CORS policy and the frontend server's origin are correctly aligned, resolving the errors.

+# Upgrading Meilisearch
+
+Meilisearch, the search engine used by Open Archiver, requires a manual data migration process when upgrading to a new version. This is because Meilisearch databases are only compatible with the specific version that created them.
+
+If an Open Archiver upgrade includes a major Meilisearch version change, you will need to migrate your search index by following the process below.
+
+## Experimental: Dumpless Upgrade
+
+> **Warning:** This feature is currently **experimental**. We do not recommend using it for production environments until it is marked as stable. Please use the [standard migration process](#standard-migration-process-recommended) instead. Proceed with caution.
+
+Meilisearch recently introduced an experimental "dumpless" upgrade method. This allows you to migrate the database to a new Meilisearch version without manually creating and importing a dump. However, please note that **dumpless upgrades are not currently atomic**. If the process fails, your database may become corrupted, resulting in data loss.
+
+**Prerequisite: Create a Snapshot**
+
+Before attempting a dumpless upgrade, you **must** take a snapshot of your instance. This ensures you have a recovery point if the upgrade fails. Learn how to create snapshots in the [official Meilisearch documentation](https://www.meilisearch.com/docs/learn/data_backup/snapshots).

+To perform a dumpless upgrade, you need to configure your Meilisearch instance with the experimental flag. You can do this in one of two ways:
+
+**Option 1: Using an Environment Variable**
+
+Add the `MEILI_EXPERIMENTAL_DUMPLESS_UPGRADE` environment variable to your `docker-compose.yml` file for the Meilisearch service.
+
+```yaml
+services:
+  meilisearch:
+    image: getmeili/meilisearch:v1.x # The new version you want to upgrade to
+    environment:
+      - MEILI_MASTER_KEY=${MEILI_MASTER_KEY}
+      - MEILI_EXPERIMENTAL_DUMPLESS_UPGRADE=true
+```
+
+**Option 2: Using a CLI Option**
+
+Alternatively, you can pass the `--experimental-dumpless-upgrade` flag in the command section of your `docker-compose.yml`.
+
+```yaml
+services:
+  meilisearch:
+    image: getmeili/meilisearch:v1.x # The new version you want to upgrade to
+    command: meilisearch --experimental-dumpless-upgrade
+```
+
+After updating your configuration, restart your container:
+
+```bash
+docker compose up -d
+```
+
+Meilisearch will attempt to migrate your database to the new version automatically.
+
+---
+
+## Standard Migration Process (Recommended)
+
+For self-hosted instances using Docker Compose, the recommended migration process involves creating a data dump from your current Meilisearch instance, upgrading the Docker image, and then importing that dump into the new version.
+
+### Step 1: Create a Dump
+
+Before upgrading, you must create a dump of your existing Meilisearch data. You can do this by sending a POST request to the `/dumps` endpoint of the Meilisearch API.
+
+1.  **Find your Meilisearch container name**:
+
+    ```bash
+    docker compose ps
+    ```
+
+    Look for the service name that corresponds to Meilisearch, usually `meilisearch`.
+
+2.  **Execute the dump command**:
+    You will need your Meilisearch Admin API key, which can be found in your `.env` file as `MEILI_MASTER_KEY`.
+
+    ```bash
+    curl -X POST 'http://localhost:7700/dumps' \
+      -H "Authorization: Bearer YOUR_MEILI_MASTER_KEY"
+    ```
+
+    This will start the dump creation process. The dump file will be created inside the `meili_data` volume used by the Meilisearch container.
+
+3.  **Monitor the dump status**:
+    The dump creation request returns a `taskUid`. You can use this to check the status of the dump.
+
+    For more details on dump and import, see the [official Meilisearch documentation](https://www.meilisearch.com/docs/learn/update_and_migration/updating).
+
+### Step 2: Upgrade Your Open Archiver Instance
+
+Once the dump is successfully created, you can proceed with the standard Open Archiver upgrade process.
+
+1.  **Pull the latest changes and Docker images**:
+
+    ```bash
+    git pull
+    docker compose pull
+    ```
+
+2.  **Stop the running services**:
+    ```bash
+    docker compose down
+    ```
+
+### Step 3: Import the Dump
+
+Now, you need to restart the services while telling Meilisearch to import from your dump file.
+
+1.  **Modify `docker-compose.yml`**:
+    You need to temporarily add the `--import-dump` flag to the Meilisearch service command. Find the `meilisearch` service in your `docker-compose.yml` and modify the `command` section.
+
+    You will need the name of your dump file. It will be a `.dump` file located in the directory mapped to `/meili_data` inside the container.
+
+    ```yaml
+    services:
+        meilisearch:
+            # ... other service config
+            command:
+                [
+                    '--master-key=${MEILI_MASTER_KEY}',
+                    '--env=production',
+                    '--import-dump=/meili_data/dumps/YOUR_DUMP_FILE.dump',
+                ]
+    ```
+
+2.  **Restart the services**:
+    ```bash
+    docker compose up -d
+    ```
+    Meilisearch will now start and import the data from the dump file. This may take some time depending on the size of your index.
+
+### Step 4: Clean Up
+
+Once the import is complete and you have verified that your search is working correctly, you should remove the `--import-dump` flag from your `docker-compose.yml` to prevent it from running on every startup.
+
+1.  **Remove the `--import-dump` line** from the `command` section of the `meilisearch` service in `docker-compose.yml`.
+2.  **Restart the services** one last time:
+    ```bash
+    docker compose up -d
+    ```
+
+Your Meilisearch instance is now upgraded and running with your migrated data.
+
+For more advanced scenarios or troubleshooting, please refer to the **[official Meilisearch migration guide](https://www.meilisearch.com/docs/learn/update_and_migration/updating)**.

+# Upgrading Your Instance
+
+This guide provides instructions for upgrading your Open Archiver instance to the latest version.
+
+## Checking for New Versions
+
+Open Archiver automatically checks for new versions and will display a notification in the footer of the web interface when an update is available. You can find a list of all releases and their release notes on the [GitHub Releases](https://github.com/LogicLabs-OU/OpenArchiver/releases) page.
+
+## Upgrading Your Instance
+
+To upgrade your Open Archiver instance, follow these steps:
+
+1.  **Pull the latest changes from the repository**:
+
+    ```bash
+    git pull
+    ```
+
+2.  **Pull the latest Docker images**:
+
+    ```bash
+    docker compose pull
+    ```
+
+3.  **Restart the services with the new images**:
+    ```bash
+    docker compose up -d
+    ```
+
+This will restart your Open Archiver instance with the latest version of the application.
+
+## Migrating Data
+
+When you upgrade to a new version, database migrations are applied automatically when the application starts up. This ensures that your database schema is always up-to-date with the latest version of the application.
+
+No manual intervention is required for database migrations.
+
+## Upgrading Meilisearch
+
+When an Open Archiver update includes a major version change for Meilisearch, you will need to manually migrate your search data. This process is not covered by the standard upgrade commands.
+
+For detailed instructions, please see the [Meilisearch Upgrade Guide](./meilisearch-upgrade.md).
