-# Setting up NadekoBot with Docker
+# Deploying NadekoBot with Docker: A Comprehensive Guide
 
-# WORK IN PROGRESS
+## Getting Started
 
-### Installation
+Ensure Docker and Docker Compose are installed on your system. If not, follow the official Docker guides for your specific operating system:
+
+- [Docker Installation Guide](https://docs.docker.com/engine/install/)
+- [Docker Compose Installation Guide](https://docs.docker.com/compose/install/)
+
+## Step-by-Step Installation
+
+1. **Choose Your Workspace:** Select a directory where you'll set up your NadekoBot stack. Use your terminal to navigate to this directory. For the purpose of this guide, we'll use `/opt/stacks/nadekobot/` as an example, but you can choose any directory that suits your needs.
+
+2. **Create a Docker Compose File:** In this directory, create a Docker Compose file named `docker-compose.yml`. You can use any text editor for this task. For instance, to use the `nano` editor, type `nano docker-compose.yml`.
+
+3. **Configure Your Docker Compose File:** Populate your Docker Compose file with the following configuration:
 
-1. Create a `/srv/nadeko` folder 
-  - `mkdir -p /srv/nadeko`
-2. Create a `docker-compose.yml`
-  - nano `docker-compose.yml`
-  - copy the following contents into it:
-##### docker-compose.yml 
 ```yml
-version: "3.7"
 services:
   nadeko:
     image: registry.gitlab.com/kwoth/nadekobot:latest
-    depends_on:
+    container_name: nadeko
-      - redis
+    restart: unless-stopped
     environment:
-      TZ: Europe/Paris
+      TZ: Europe/Rome
-      NadekoBot_RedisOptions: redis,name=nadeko
-      #NadekoBot_ShardRunCommand: dotnet
-      #NadekoBot_ShardRunArguments: /app/NadekoBot.dll {0} {1}
     volumes:
-      - /srv/nadeko/conf/creds.yml:/app/creds.yml:ro
+      - /opt/stacks/nadekobot/conf/creds.yml:/app/data/creds.yml
-      - /srv/nadeko/data:/app/data
+      - /opt/stacks/nadekobot/data:/app/data
-
+networks: {}
-  redis:
-    image: redis:4-alpine
-    sysctls:
-      - net.core.somaxconn=511
-    command: redis-server --maxmemory 32M --maxmemory-policy volatile-lru
-    volumes:
-      - /srv/nadeko/redis-data:/data
 ```
-3. Save your file and run docker compose
-  - `docker-compose up`  
-4. Edit creds in `/srv/nadeko/conf/creds.yml`
-5. Run it again with
-  - `docker-compose up`
 
-### Updating
+4. **Prepare Your Credentials File:** Before running Docker Compose, ensure the `creds.yml` file exists in the `/opt/stacks/nadekobot/conf/` directory. If it's missing, create it using `touch /opt/stacks/nadekobot/conf/creds.yml`. You may need to use `sudo`. Remember to replace `/opt/stacks/nadekobot/` with your chosen directory.
-- `cd /srv/nadeko`
+
-- `docker-compose pull`
+5. **Edit Your Credentials File:** Populate the `creds.yml` file in `/opt/stacks/nadekobot/conf/creds.yml` with your bot's credentials. You can use any text editor for this task. For instance, to use the `nano` editor, type `nano /opt/stacks/nadekobot/conf/creds.yml`. You may need to use `sudo`. Again, replace `/opt/stacks/nadekobot/` with your chosen directory.
-- `docker-compose up -d`
+
+6. **Launch Your Bot:** Now, you're ready to run Docker Compose. Use the following command: `docker-compose up -d`.
+
+## Keeping Your Bot Up-to-Date
+
+There are two methods to update your NadekoBot:
+
+### Manual Update
+
+1. **Navigate to Your Directory:** Use `cd /path/to/your/directory` to go to the directory containing your Docker Compose file.
+
+2. **Pull the Latest Images:** Use `docker-compose pull` to fetch the latest images.
+
+3. **Restart Your Containers:** Use `docker-compose up -d` to restart the containers.
+
+### Automatic Update with Watchtower
+
+If you prefer an automated update process, consider using Watchtower. Watchtower automatically updates your Docker containers to the latest versions. 
+
+To use Watchtower with NadekoBot, you need to add a specific label to the service in your Docker Compose file. Here's how your Docker Compose file should look:
+
+```yml
+services:
+  nadeko:
+    image: registry.gitlab.com/kwoth/nadekobot:latest
+    container_name: nadeko
+    restart: unless-stopped
+    labels:
+      - com.centurylinklabs.watchtower.enable=true
+    environment:
+      TZ: Europe/Rome
+    volumes:
+      - /opt/stacks/nadekobot/conf/creds.yml:/app/data/creds.yml
+      - /opt/stacks/nadekobot/data:/app/data
+networks: {}
+```
+
+Remember to replace `/opt/stacks/nadekobot/` with your chosen directory in the Docker Compose file.
+
+To install and run Watchtower, follow the guide provided by Containrrr:
