+
+## Using docker-compose and the prebuilt-image (recommended)
+
+This is the easiest method for running the bot without any modifications.  
+**Do not clone the repository when using this method!**
+
+1. Create a new directory and `cd` into it.
+
+2. Create the `docker-compose.yml` file:
+
+    ```yaml
+    version: '3'
+    services:
+      qrm2:
         image: "classabbyamp/discord-qrm2:latest"
-        container_name: "discord-qrm2"
+        restart: on-failure
         volumes:
-            - "./data:/app/data:rw"
-```
+          - "./data:/app/data:rw"
+        environment:
+          - PYTHONUNBUFFERED=1
+    ```
+
+3. Create a subdirectory named `data`.
+
+4. Copy the templates for `options.py` and `keys.py` to `data/`, and edit them.
+
+5. Run `docker-compose`:
+
+    ```none
+    $ docker-compose pull
+    $ docker-compose up -d
+    ```
+
+    > Run without "-d" to test the bot. (run in foreground)
+
+
+
+## Using docker-compose and building the image
+
+This is the easiest method to run the bot with modifications.
+
+1. `cd` into the repository.
+
+2. Create the `docker-compose.yml` file:
+
+    ```yaml
+    version: '3'
+    services:
+      qrm2:
+        build: .
+        image: "discord-qrm2:local-latest"
+        restart: on-failure
+        volumes:
+          - "./data:/app/data:rw"
+        environment:
+          - PYTHONUNBUFFERED=1
+    ```
+
+3. Create a subdirectory named `data`.
+
+4. Copy the templates for `options.py` and `keys.py` to `data/`, and edit them.
+
+5. Run `docker-compose`:
+
+    ```none
+    $ docker-compose build --pull
+    $ docker-compose -d
+    ```
+
+    > Run without "-d" to test the bot. (run in foreground)
+
+
+
+## Using pure docker
+
+This methods is not very nice to use.  
+*I just wanna run the darn thing, not do gymnastics!*
+
+
+### [Optional] Building the image
+
+1. `cd` into the repository.
+
+2. Run docker build:
+
+    ```none
+    $ docker build -t discord-qrm2:local-latest .
+    ```
+
+
+### Creating the container
+
+1. Be in a directory with a `data/` subdirectory, which should contain valid `options.py` and `keys.py` files (copy and edit the templates).
+
+2. Run the container:
+
+    ```none
+    $ docker run -d --rm --mount type=bind,src=$(pwd)/data,dst=/app/data --name qrm2 [image]
+    ```
+
+    Whereas `[image]` is either of:
+    - `discord-qrm2:local-latest` if you are building your own.
+    - `classabbyamp/discord-qrm2:latest` if you want to use the prebuilt image.
