 1. [Fork the wolt_modal_sheet repo](https://github.com/woltapp/wolt_modal_sheet/fork) on GitHub.
 2. Clone your forked repo locally.
 3. Ensure you have [Melos](https://pub.dev/packages/melos/install) installed.
-   ```bash
-   dart pub global activate melos
-   ```
+
+      ```bash
+      dart pub global activate melos
+      ```
+
 4. Use Melos to bootstrap the project.
-   ```bash
-   melos bootstrap
-   ```
-5. Create a new branch from the `main` branch.
-6. Make your changes.
-7. Run Melos format to format the code.
-   ```bash
-   melos format
-   ```
-8. Run Melos analyze to identify any issues.
-   ```bash
-   melos analyze
-   ```
-9. Make sure all existing tests pass and add new tests for the changes you made.
-   Execute the following command to run the tests.
-   ```bash
-   melos test
-   ```
-10. Create a pull request.
+
+      ```bash
+      melos bootstrap
+      ```
+
+5. Ensure DCM (dcm.dev) is installed and activated
+      - Enabling and activating DCM is optional. When you open a PR, the CI bots will show you any DCM warnings introduced
+      by your change which should be fixed before submitting. please follow instructions at <https://dcm.dev/pricing/>. You can either use the free tier of DCM, or purchase a pro or team license. Note that the free tier doesn't support all the rules of the paid tier, so you will also need to consult the output of the `Dart Code Metrics workflow on Github` when you open your PR. To enable DCM check this [quick start guide](https://dcm.dev/docs/quick-start/)
