-To build and push the Docker image (if logged into a Docker registry):
-```powershell
-./build-and-push.ps1 -Tag dev

 ## Database Migrations
 
+Lingarr uses [FluentMigrator](https://fluentmigrator.github.io/) with a single shared migration project (`Lingarr.Migrations`) that supports SQLite, MySQL, and PostgreSQL.
+
 ### Creating New Migrations
-Use the provided PowerShell script to create migrations:
-```powershell
-./create-migrations.ps1 -MigrationName "YourMigrationName"
+Add a new file to `Lingarr.Migrations/Migrations/` following the naming convention:
+
+```
+M{NNNN}_{MigrationName}.cs
+```
+
+Example — `M0006_AddMyTable.cs`:
+```csharp
+using FluentMigrator;
+
+namespace Lingarr.Migrations.Migrations;
+
+[Migration(6)]
+public class M0006_AddMyTable : Migration
+{
+    public override void Up()
+    {
+        Create.Table("my_table")
+            .WithColumn("id").AsInt32().PrimaryKey().Identity()
+            .WithColumn("name").AsCustom("TEXT").NotNullable();
+    }
+
+    public override void Down()
+    {
+        Delete.Table("my_table");
+    }
+}
 ```
 
-This will create migrations for both SQLite and MySQL providers.
+- The `[Migration(N)]` version number must be unique and sequential
+- Always implement `Down()` to make migrations reversible
 
 ### Applying Migrations
 Migrations are automatically applied when the application starts.
