+# How to add new notifier to Postgresus (Discord, Slack, Telegram, Email, Webhook, etc.)
+
+## Backend part
+
+1. Create new model in `backend/internal/features/notifiers/models/{notifier_name}/` folder. Implement `NotificationSender` interface from parent folder.
+   - The model should implement `Send(logger *slog.Logger, heading string, message string) error` and `Validate() error` methods
+   - Use UUID primary key as `NotifierID` that references the main notifiers table
+
+2. Add new notifier type to `backend/internal/features/notifiers/enums.go` in the `NotifierType` constants.
+
+3. Update the main `Notifier` model in `backend/internal/features/notifiers/model.go`:
+   - Add new notifier field with GORM foreign key relation
+   - Update `getSpecificNotifier()` method to handle the new type
+   - Update `Send()` method to route to the new notifier
+
+4. If you need to add some .env variables to test, add them in `backend/internal/config/config.go` (so we can use it in tests)
+
+5. If you need some Docker container to test, add it to `backend/docker-compose.yml.example`. For sensitive data - keep it blank.
+
+6. If you need some sensitive envs to test in pipeline, message @rostislav_dugin so I can add it to GitHub Actions. For example, API keys or credentials.
+
+7. Create new migration in `backend/migrations` folder:
+   - Create table with `notifier_id` as UUID primary key
+   - Add foreign key constraint to `notifiers` table with CASCADE DELETE
+   - Look at existing notifier migrations for reference
+
+8. Make sure that all tests are passing.
+
+## Frontend part
+
+If you are able to develop only backend - it's fine, message @rostislav_dugin so I can complete UI part.
+
+1. Add models and validator to `frontend/src/entity/notifiers/models/{notifier_name}/` folder and update `index.ts` file to include new model exports.
+
+2. Upload an SVG icon to `public/icons/notifiers/`, update `src/entity/notifiers/models/getNotifierLogoFromType.ts` to return new icon path, update `src/entity/notifiers/models/NotifierType.ts` to include new type, and update `src/entity/notifiers/models/getNotifierNameFromType.ts` to return new name.
+
+3. Add UI components to manage your notifier:
+   - `src/features/notifiers/ui/edit/notifiers/Edit{NotifierName}Component.tsx` (for editing)
+   - `src/features/notifiers/ui/show/notifier/Show{NotifierName}Component.tsx` (for display)
+
+4. Update main components to handle the new notifier type:
+   - `EditNotifierComponent.tsx` - add import, validation function, and component rendering
+   - `ShowNotifierComponent.tsx` - add import and component rendering
+
+5. Make sure everything is working as expected.

-# React + TypeScript + Vite
+# Frontend Development
 
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+## Development
 
-Currently, two official plugins are available:
+To run the development server:
 
-- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) for Fast Refresh
-- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
-
-## Expanding the ESLint configuration
-
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
-
-```js
-export default tseslint.config({
-  extends: [
-    // Remove ...tseslint.configs.recommended and replace with this
-    ...tseslint.configs.recommendedTypeChecked,
-    // Alternatively, use this for stricter rules
-    ...tseslint.configs.strictTypeChecked,
-    // Optionally, add this for stylistic rules
-    ...tseslint.configs.stylisticTypeChecked,
-  ],
-  languageOptions: {
-    // other options...
-    parserOptions: {
-      project: ['./tsconfig.node.json', './tsconfig.app.json'],
-      tsconfigRootDir: import.meta.dirname,
-    },
-  },
-});
+```bash
+npm run dev
 ```
 
-You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+## Build
 
-```js
-// eslint.config.js
-import reactDom from 'eslint-plugin-react-dom';
-import reactX from 'eslint-plugin-react-x';
+To build the project for production:
 
-export default tseslint.config({
-  plugins: {
-    // Add the react-x and react-dom plugins
-    'react-x': reactX,
-    'react-dom': reactDom,
-  },
-  rules: {
-    // other rules...
-    // Enable its recommended typescript rules
-    ...reactX.configs['recommended-typescript'].rules,
-    ...reactDom.configs.recommended.rules,
-  },
-});
+```bash
+npm run build
 ```
+
+This will compile TypeScript and create an optimized production build.
+
+## Code Quality
+
+### Linting
+
+To check for linting errors:
+
+```bash
+npm run lint
+```
+
+### Formatting
+
+To format code using Prettier:
+
+```bash
+npm run format
+```
+
+This will automatically format all TypeScript, JavaScript, JSON, CSS, and Markdown files.
