+## Development Environment
+
+### Dev Container
+
+Install [Docker](https://docs.docker.com/compose/install/). Once installed, a clean dev environment with a Docker container [native to VSCode](https://code.visualstudio.com/docs/devcontainers/create-dev-container#_dockerfile) is spun up automatically. 
+
+* [Command palette](https://code.visualstudio.com/docs/getstarted/userinterface#_command-palette) (⇧⌘P) > Dev Containers: Reopen in Container
+* F5 for debug
+    * May need to select interpreter (e.g., `/opt/venv/bin/python`) first

+
+### Manual Docker Instance
+
+If VSCode isn't present or only the python portion (cf. `__init__.py`) is being worked on, it's possible to just run a Docker container on its own. The container installs the correct version of python and any dependencies (e.g., ipython, rich) in `requirements.txt`.
+
+```bash
+# navigate to directory with Dockerfile
+cd .devcontainer/
+
+# build image
+docker build -t nonsteamlaunchers .
+
+# run container
+docker run -it --rm --name=mynonsteamlaunchers --workdir=/app -v $(pwd):/app nonsteamlaunchers bash
+
+# exit container
+exit
+```
+
+### Python virtual environment
+
+Useful for the python module(s), but extra compared to the [dev container](#dev-container) portion that covers the core shell script.
+
+```bash
+# create virtual environment
+python -m venv .venv
+
+# activate virtual environment
+source .venv/bin/activate
+
+# install dependencies
+python -m pip install -r requirements.txt 
+```
+
+### Additional tooling
+
+Additional tooling includes but is not limited to:
+
+#### asdf
+
+* Install [asdf](https://asdf-vm.com/guide/getting-started.html#_2-download-asdf)
+* Usage
+    ```bash
+    # add python plugin
+    asdf plugin-add python
+
+    # install stable python
+    asdf install python <latest|3.11.4>
+
+    # set stable to system python
+    asdf global python latest
+
+    # add poetry asdf plugin
+    asdf plugin-add poetry https://github.com/asdf-community/asdf-poetry.git
+
+    # install latest version via asdf
+    asdf install poetry <latest|1.5.1>
+
+    # set latest version as default
+    asdf global poetry latest
+    ```
+
+#### shellcheck
+
+`.shellcheckrc` excludes various [bash language rules](https://github.com/koalaman/shellcheck/wiki/Ignore#ignoring-one-or-more-types-of-errors-forever). Useful to control noise vs. legitimate warnings/errors when using the shellcheck extension.
