-2. Clone your fork locally. Replace `[your-username]` with your GitLab username and `[project-name]` with the actual project name:
-    ```bash
-    git clone $(git config --get remote.origin.url)
-    ```
-3. Add the upstream repository. Replace `[original-username]` and `[project-name]` with the original repository'\''s username and project name:
-    ```bash
-    git remote add upstream https://gitlab.schukai.com/[original-username]/[project-name].git
-    ```
-
-### Making Changes
-
-1. Create a new branch:
-    ```bash
-    git checkout -b new-feature-branch
-    ```
-2. Make your changes.
-3. Commit your changes:
-    ```bash
-    git commit -m "Description of change"
-    ```
-
-### Submitting a Merge Request
-
-1. Push your changes to your fork:
-    ```bash
-    git push origin new-feature-branch
-    ```
-2. Navigate to the original project repository on `gitlab.schukai.com`.
-3. Open a Merge Request and provide a clear description of the changes.
-
-## Coding Guidelines
-
-- Follow the coding style used in the project.
