+### Environment-Specific Versioning with Realms
+
+#### Overview
+
+We have introduced a new feature that allows users to apply version-specific changes based on their configured environment, or "realm". This ensures that certain changes are only applied when the user is operating within a specific realm, providing an additional layer of customization and control.
+
+#### Configuration
+
+To make use of this feature, you need to configure your realm in the `versionConfig` table. Set your realm by inserting or updating a record in this table. The `realm` field should contain the identifier of your environment.
+
+#### File Naming Convention
+
+To designate a file as realm-specific, include a `.your_realm.` segment before the file extension. For example, if your realm is set to 'ab', the file should be named like this: `filename.ab.sql`.
+
+#### How It Works
+
+1. **Set your Realm**: Configure your realm in the `versionConfig` table.
+  
+2. **Add Files**: Place your realm-specific files in the `versions` folder. Make sure to follow the naming convention.
+
+3. **Version Order**: Files are applied in the existing version order. In addition to that, the realm is validated.
+
+4. **Apply Changes**: Run the usual versioning commands. The realm-specific files will only be applied if your configured realm matches the realm in the file name.
+
+#### Important Notes
+
+- If no realm is configured, realm-specific files will be ignored.
+  
+- If you have a realm configured but the realm-specific files belong to a different realm, those files will also be ignored.
+
+This feature allows for greater flexibility when working in different environments, making it easier to manage realm-specific changes in a shared repository.
