+## Engineering philosophy
 
 **Think like a skeptical senior engineer and code reviewer. Don't just do what was asked—also think about what should have been asked.**

+### Add reasonable new lines between logical statements
+
+**Add blank lines between logical blocks to improve code readability.**
+
+Separate different logical operations within a function with blank lines. This makes the code flow clearer and helps identify distinct steps in the logic.
+
+#### Guidelines:
+
+- Add blank line before final `return` statement
+- Add blank line after variable declarations before using them
+- Add blank line between error handling and subsequent logic
+- Add blank line between different logical operations
+
+#### Bad example (without spacing):
+
+```go
+func (t *Task) BeforeSave(tx *gorm.DB) error {
+	if len(t.Messages) > 0 {
+		messagesBytes, err := json.Marshal(t.Messages)
+		if err != nil {
+			return err

+			return err

+		t.Messages = messages
+	}

-## 📖 Migration guide
-
-Databasus is the new name for Postgresus. You can stay with latest version of Postgresus if you wish. If you want to migrate - follow installation steps for Databasus itself.
-
-Just renaming an image is not enough as Postgresus and Databasus use different data folders and internal database naming.
-
-You can put a new Databasus image with updated volume near the old Postgresus and run it (stop Postgresus before):

-Then manually move databases from Postgresus to Databasus.
-
-### Why was Postgresus renamed to Databasus?
-
-Databasus has been developed since 2023. It was internal tool to backup production and home projects databases. In start of 2025 it was released as open source project on GitHub. By the end of 2025 it became popular and the time for renaming has come in December 2025.
-
-It was an important step for the project to grow. Actually, there are a couple of reasons:
-
-1. Postgresus is no longer a little tool that just adds UI for pg_dump for little projects. It became a tool both for individual users, DevOps, DBAs, teams, companies and even large enterprises. Tens of thousands of users use Postgresus every day. Postgresus grew into a reliable backup management tool. Initial positioning is no longer suitable: the project is not just a UI wrapper, it's a solid backup management system now (despite it's still easy to use).
-
-2. New databases are supported: although the primary focus is PostgreSQL (with 100% support in the most efficient way) and always will be, Databasus added support for MySQL, MariaDB and MongoDB. Later more databases will be supported.
-
-3. Trademark issue: "postgres" is a trademark of PostgreSQL Inc. and cannot be used in the project name. So for safety and legal reasons, we had to rename the project.
-
 ## AI disclaimer
 
 There have been questions about AI usage in project development in issues and discussions. As the project focuses on security, reliability and production usage, it's important to explain how AI is used in the development process.
