+# Dev environment
+
+This docker setup is supposed to get a running system for local development.
+
+## Run locally
+
+* Compose Docker containers:
+  ~~~
+  cd docker_app
+  docker compose up -d
+  ~~~
+  (Linux users may need `sudo` or `docker login`)
+
+* Open [localhost:8080](http://localhost:8080) in your browser \
+  Logins are defined at first use. (There may be example data in the future)
+
+## Additonal information
+
+### Inspect database
+Open [localhost:8888](http://localhost:8888) in your browser for phpmyadmin \
+Login: `mrbs:mrbs`
+
+Alternatively, you can connect to the database using the command like tool `mysql`:
+~~~
+docker-compose db mysql -u mrbs -pmrbs mrbs
+~~~
+
+### View logs
+
+View apache webserver logs:
+~~~
+docker compose logs www
+~~~
+View database logs:
+~~~
+docker compose logs db
+~~~
+
+
+### Live reloading
+The repository's source code is mounted into the docker containers. That means, changes of code take effect immediately after refreshing the browser.
+
+However, when configuration of php and database is change, you have to reset the containers.
+
+### Reset containers
+
+* Stop Docker containers:
+  ~~~
+  docker compose down
+  ~~~
+* Delete persisted volumes:
+  ~~~
+  docker volume prune
+  ~~~
+* Rebuild container images:
+  ~~~
+  docker compose build
+  ~~~
+
