 I recommend installing something like [forever.js](https://www.npmjs.com/package/forever) which will make it start back up again if it errors at some point
 
 If you run into issues feel free to dm me on Matrix [here](https://matrix.to/#/@ategon:matrix.org)

+## Setup with Docker
+1. Clone the repository
+2. Create an account in the instance you want the bot to have as its home (just make a regular user)
+3. Create a file called .env in the bot folder and give it values in this format with the data in the quotes (dont add the slashes or the part after the slashes)
+```
+LEMMY_INSTANCE="" // The instance the bot account is in
+LEMMY_USERNAME="" // The bot username
+LEMMY_PASSWORD="" // The bot password
+```
+4. Change the data in config.yaml based on what you want set. Set the communities and feeds you want here
+5. In the project directory build the docker image by running `docker build -t <your name>/<desired_image_name>` and then launch a new container with `docker run <your name>/<desired_image_name>`
