+# how to use docker development?
+
+## How to setup?
+ 1. have docker installed
+ 2. create a `config.env` in `/.docker/development`. inspire its contents from `example.config.env`
+
+## how to run?
+ 1. while in directory `/.docker/development` run `docker compose up -d`
+ 1.1 if running first time in docker, make sure you have no node_modules folder present in `/`.
+
+## not working? try this:
+ 1. while in directory `/.docker/development` run `docker compose down -v`
+ 2. remove `node_modules` directory in `/` if it exists
+ 3. remove `.env` and `config.json` file in `/` if any of them exist
+ 4. while in directory `/.docker/development` run `docker compose up -d --build`
+
+## how to stop?
+ 1. while in directory `/.docker/development` run `docker compose down`
+> NOTE: if you want also delete all saved data for a full reset, run `docker compose down -v` instead
+
+## how do I access the terminal for the backend service?
+make sure the docker services are running, then run `docker attach mw_backend-1`.
+this will appear to show nothing at first, but all new logs will show up,
+and anything you type in the terminal now affect the backend service.
+> Warning: doing CTRL+C will shut down the backend service, it will not kick your terminal back to its original shell.
+
+## how do I read logs?
+ 1. while in directory `/.docker/development` run `docker compose ps`
+ 2. note the name of the service you want to see the logs of
+ 3. while in directory `/.docker/development` run `docker compose logs <NAME>`. fill in the name of the service without the brackets.
+
+## Exposed ports
+ - http://localhost:8081 - backend API
+ - http://localhost:8082 - postgres web UI
+ - postgres://localhost:5432 - postgres
