+# Database Migration with Atlas
+
+This project uses [Atlas](https://atlasgo.io/) for database schema management and migrations.
+
+## 📋 Prerequisites
+
+1. **Download and Install Atlas CLI**  
+   Run the following command in PowerShell or Git Bash:
+
+   ```sh
+   curl -sSf https://atlasgo.sh | sh
+   ```
+    Verify installation:
+
+    ```sh
+    atlas version
+    ```
+
+2. Install GORM Provider
+    Run inside your Go project:
+
+    ```sh
+    go get -u ariga.io/atlas-provider-gorm
+    ```
+
+3. Create atlas.hcl configuration file
+   Just create an atlas.hcl file in your project root as example given at atlas.hcl.example
+4. Create migrations folder
+    ```sh
+    mkdir migrations
+    ```
+5. Usage
+You can use the provided Makefile for common commands:
+
+    Generate a migration diff
+    ```sh
+    make diff
+    ```
+
+    Apply migrations
+    ```sh
+    make apply
+    ```
+
+    Compute schema hash
+    ```sh
+    make hash
+    ```
+
+    If you don’t have make installed, you can run the Atlas commands directly:
+    ```sh
+    atlas migrate diff --env gorm
+    ```
+    ```sh
+    atlas migrate apply --env gorm
+    ```
+    ```sh
+    atlas migrate hash
+    ```
