 # 🌏️ ExoPlaSim Docker
 
-## Environment Variables
+## Instructions
+1. Create an ExoPlaSim model.
+2. Replace the example model in the `build` directory with your own model (keeping the filename `model.py`).
+3. Run the docker container (eg. `docker compose run -it --rm exoplasim`).
+
+## Optional Environment Variables
 
 **UID:** UID of host/guest user.
 
 **GID:** GID of host/guest user.
 
-**MODEL:** Path to model (required).
+**BUILD_DIR:** Path to build directory.
 
-## Instructions
-1. Create an ExoPlaSim model
-2. Save it somewhere with the filename `model.py`
-3. Edit the `.env` file and add the directory containing `model.py` after `MODEL=`
-4. Run the docker container (eg. `docker compose run -it --rm exoplasim`)
