 Follow these steps to set up and configure the project:

 1. **Clone the repository**:
-    
+
    ```
    git clone https://gitea.leaf.home.kappeh.org/Homelab/minecraft_server.git
    cd minecraft_server
    ```
-    
+
 2. **Create required directories**: See [Directory Setup](#directory-setup) for details.
-    
+
 3. **Set up environment variables**: See [Environment Variables](#environment-variables) for details.
- 
+
 4. **Import world files**:
-    
+
    The world for the Fabric server is located at `fabric/data/world`. If you want to use an existing world, copy it to this location before running the container:
-    
+
    ```
    cp path/to/world fabric/data/world
    ```
-   
+
 5. **Adjust permissions (recommended)**: Run the following commands in the root of the repository, replacing `PUID` and `PGID` with the corresponding values from your `.env` file:
-    
+
    ```
    sudo chown -R PUID:PGID .
    sudo chmod -R 770 .
    ```
-   
+
 6. **Start the Docker Compose stack**: To start the services in detached mode, run:
-    
+
    ```
    docker compose up -d
    ```
-    
+
 7. **Stop the Docker Compose stack**: To stop and remove the running containers, use:
-    
+
    ```
    docker compose down
    ```
-    
+
 ## Directory Setup

 Make a directory called `schematics` in the root of the repository. This directory is used for storing [WorldEdit](https://worldedit.org/) schematic files. To create it, run:

 Instead of using environment variables, the secrets section of `docker-compose.yml` can be modified to read files instead. This method will likely be used by default in future.

 For this to work you must first [setup a discord bot](https://github.com/Kalimero2Team/dclink/wiki/Setup-Discord-Bot). Then set the relevant [Environment Variables](#environment-variables).
