+# FxMigrant
+_automated database migrations for CitizenFX servers_
+
+## Installation
+1. Download the latest release from GitHub releases.
+2. Extract it someplace in your resources directory.
+3. Currently, only MySQL is supported. Use a valid MySQLConnector connection string as `mysql_connection_string` convar. Typically, `mysql-async` already uses this kind of string.
+4. Run a resource that uses FxMigrant.
+
+Currently (2019-05-25), it's unlikely for Linux servers to work with this as-is, this might need either a new artifact build or the usual copying of CitizenFX.Core.Server.dll.
+
+## Building
+1. Clone the repository.
+2. Make sure you have .NET Core SDK installed.
+3. Run build.ps1.
+
+## Using
+Reference [FluentMigrator](https://fluentmigrator.github.io/) migration .cs files in your \_\_resource.lua:
+
+```lua
+migration_files {
+    'migrations/0001_create_users.cs',
+    'migrations/0002_add_license.cs
+}
+
+dependency 'fxmigrant'
+
+server_script '@fxmigrant/helper.lua'
+```
+
+Also, instead of `MySQL.ready`, use `Migrant.ready`.
+
+Example files to show the point:
+
+### 0001_create_users.cs
+```cs
+using FluentMigrator;
+
+[Migration(1)]
+public class CreateUsers : Migration
+{
+    public override void Up()
+    {
+        Create.Table("users")
+            .WithColumn("identifier").AsString().NotNullable().PrimaryKey()
+            .WithColumn("money").AsInt64().Nullable()
+            .WithColumn("bank").AsInt64().Nullable()
+            .WithColumn("permission_level").AsInt32().Nullable()
+            .WithColumn("group").AsString().Nullable();
+    }
+
+    public override void Down()
+    {
+        Delete.Table("users");
+    }
+}
+```
+
+### 0002_add_license.cs
+```cs
+using FluentMigrator;
+
+[Migration(2)]
+public class AddLicense : Migration
+{
+    public override void Up()
+    {
+        Create.Column("license")
+            .OnTable("users")
+            .AsString()
+            .Nullable()
+            .WithDefaultValue("");
+    }
+
+    public override void Down()
+    {
+        Delete.Column("license").FromTable("users");
+    }
+}
+```
