-Docker Compose file contains default settings for deploying in local directory and it's set to bind port `8000` to localhost.
+See `docker-compose.yaml` for all compose options examples
+
+### Update git repo based deployment
+Assuming you are using git repository as source of documentation there are two options available for updating the content of the docs.
+
+#### Manual
+
+Assuming that container name is `mkdocs`  
+```bash
+docker exec -ti mkdocs bootstrap update
+Pulled branch: master
+Commit: a4000c525f6db977777bf758987c4df0b44f59b4
+Commit Message: Updated nodejs
+Date: 2020-03-24 18:52:43
+Author: Przemek Ozgo
+```
+
+#### AUTO_UPDATE
+there are two environmental variables that can be used for AUTO UPDATE.
+See table above ^^
