-# Docker
+# General info
+This info applies to all configs.
+
+## Docker
 All the setups named above use Docker and docker-compose. If you're on a
 Linux-based server, you can find both `docker` and `docker-compose` in your
 package manager (do note that the Docker package might be called `docker.io`).
 Otherwise, the install instructions can be found
 [here](https://docs.docker.com/engine/install/).
 
+## Building the image
+You can build the container image using the command `docker-compose build`.
+This will build all services specified in the `docker-compose.yml` file. Any
+build configuration/environment variables can be defined in a `.env` file. A
+`.env.example` file is given for each configuration.
+
+## Running the container
+For running the server, we can use `docker-compose up -d`. This will start the
+service in the background. You can then see any logs using
+`docker-compose logs`. If you want the logs to update automatically, use
+`docker-compose logs -f`.

 # Why did I make this?
 Well, I just wanted to put all my knowledge in one basket. this makes it easier
 to manage and share with others. I spend a lot of time tweaking these configs
