-2. **Git Workflow**:
-
-   1. Add your changes to Git using `git add <file1> <file2>`.
-   2. Run `nix fmt` to lint your files.
-   3. Commit your changes with a descriptive message: `git commit -a -m "My descriptive commit message"`.
-   4. Make sure your branch has the latest changes from upstream by executing:
       ```bash
-      git fetch && git rebase origin/main --autostash
+      nix fmt
+      ```
+   - To make this automatic install the git hooks

+      ./scripts/pre-commit
       ```
-   5. Use `git status` to check for merge conflicts.
-   6. If conflicts exist, resolve them. Here's a tutorial for resolving conflicts in [VSCode](https://code.visualstudio.com/docs/sourcecontrol/overview#_merge-conflicts).
-   7. After resolving conflicts, execute `git merge --continue` and repeat step 5 until there are no conflicts.

-
+   - Go to the webinterface and open up a pull request
-   - To automatically open a pull request that gets merged if all tests pass, execute:

-
-4. **Review Your Pull Request**:
-
-   - Visit https://git.clan.lol and go to the project page. Check under "Pull Requests" for any issues with your pull request.
-
-5. **Push Your Changes**:
-   - If there are issues, fix them and redo step 2. Afterward, execute:
-     ```bash
-     git push origin HEAD:YourUsername-main
-     ```
-   - This will directly push to your open pull request.
 
 # Debugging
 
 Here are some methods for debugging and testing the clan-cli:
 
+## See all possible packages and tests
+
+To quickly show all possible packages and tests execute:
+
+```bash
+nix flake show --system no-eval
+```
+
+Under `checks` you will find all tests that are executed in our CI. Under `packages` you find all our projects.
