+
+## Installation
+
+```bash
+git clone https://github.com/iwpnd/streamlit-docker-example.git
+cd steamlit-docker-example
+
+docker-compose up -d --build
+```
+
+The container will start in detached mode and can now be accessed via [localhost:8501](http://localhost:8501). Whenever you change the app/main.py the steamlit application will update too. If you want to build upon that example, just add your dependencies to the Dockerfile and rebuild the image using docker-compose.
+
+After you are done, and you want to tear down the application, either
+
+```bash
+docker-compose stop
+```
+
+to stop the application, or use 
+
+```bash
+docker-compose down --rmi all
+```
+
+to stop the application, remove the stopped containers and optionally `--rmi all` / remove all images associated in the docker-compose.yml file.
