+This module implements the `borgbackup` backend and implements sane defaults
+for backup management through `borgbackup` for members of the clan.
+
+Configure target machines where the backups should be sent to through `targets`.
+
+Configure machines that should be backuped either through `includeMachines`
+which will exclusively add the included machines to be backuped, or through
+`excludeMachines`, which will add every machine except the excluded machine to the backup.

+The mumble clan module gives you:
+
+- True low latency voice communication.
+- Secure, authenticated encryption.
+- Free software.
+- Backed by a large and active open-source community.
+
+This all set up in a way that allows peer-to-peer hosting.
+Every machine inside the clan can be a host for mumble, 
+and thus it doesn't matter who in the network is online - as long as two people are online they are able to chat with each other.

-# Setting Up Your Git Workflow
-
-Let's set up your Git workflow to collaborate effectively:
-
-1. **Register Your Gitea Account Locally**:
-
-   - Execute the following command to add your Gitea account locally:
-     ```bash
-     tea login add
-     ```
-   - Fill out the prompt as follows:
-     - URL of Gitea instance: `https://git.clan.lol`
-     - Name of new Login [gitea.gchq.icu]: `gitea.gchq.icu:7171`
-     - Do you have an access token? No
-     - Username: YourUsername
-     - Password: YourPassword
-     - Set Optional settings: No
-
-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
+      echo 'eval "$(direnv hook zsh)"' >> ~/.zshrc && echo 'eval "$(direnv hook bash)"' >> ~/.bashrc && eval "$SHELL"
       ```
-   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.
 
-3. **Create a Pull Request**:
+4. **Create a Gitea Account**:
+      - Register an account on https://git.clan.lol
+      - Fork the [clan-core](https://git.clan.lol/clan/clan-core) repository
+      - Clone the repository and navigate to it
+      - Add a new remote called upstream:
+         ```bash
+         git remote add upstream gitea@git.clan.lol:clan/clan-core.git
+         ```
+5. **Create an access token**:
+      - Log in to Gitea.
+      - Go to your account settings.
+      - Navigate to the Applications section.
+      - Click Generate New Token.
+      - Name your token and select all available scopes.
+      - Generate the token and copy it for later use.
+      - Your access token is now ready to use with all permissions.
 
-   - To automatically open a pull request that gets merged if all tests pass, execute:
+5. **Register Your Gitea Account Locally**:
-     ```bash
-     merge-after-ci
-     ```
 
-4. **Review Your Pull Request**:
+      - Execute the following command to add your Gitea account locally:
+        ```bash
+        tea login add
+        ```
+      - Fill out the prompt as follows:
+        - URL of Gitea instance: `https://git.clan.lol`
+        - Name of new Login [git.clan.lol]:
+        - Do you have an access token? Yes
+        - Token: <yourtoken>
+        - Set Optional settings: No
 
-   - 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**:
+6. **Allow .envrc**:
-   - If there are issues, fix them and redo step 2. Afterward, execute:
+
-     ```bash
+      - When you enter the directory, you'll receive an error message like this:
-     git push origin HEAD:YourUsername-main
+        ```bash
-     ```
+        direnv: error .envrc is blocked. Run `direnv allow` to approve its content
-   - This will directly push to your open pull request.
+        ```
+      - Execute `direnv allow` to automatically execute the shell script `.envrc` when entering the directory.
+
+7. **(Optional) Install Git Hooks**:
+      - To syntax check your code you can run:
+         ```bash
+         nix fmt
+         ```
+      - To make this automatic install the git hooks
+         ```bash
+         ./scripts/pre-commit
+         ```
+
+8. **Open a Pull Request**:
+      - To automatically open up a pull request you can use our tool called:
+      ```
+      merge-after-ci --reviewers Mic92 Lassulus Qubasa
+      ```
 
 # 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.

 2. Use `cntr` and `psgrep` to attach to the Nix sandbox. This allows you to interactively debug your code while it's paused. For example:
