+If installing FLASC with the intention to develop, some additional configuration is helpful:
+
+
+Install FLASC in editable mode with the appropriate developer tools
+
+   - ``".[develop]"`` is for the linting and code checking tools
+   - ``".[docs]"`` is for the documentation building tools. Ideally, developers should also be
+     contributing to the documentation, and therefore checking that
+     the documentation builds locally.
+
+```bash
+pip install -e ".[develop, docs]"
+```
+Turn on the linting and code checking tools
+
+```bash
+pre-commit install
+```
+
+If everything is configured correctly, any changes made to the source
+code will be available directly through your local Python. Remember
+to re-import the FLASC module when changes are made if you are working
+in an interactive environment like Jupyter.
+
+# Installation
+
+FLASC is currently not available as a package on any repository manager.
+Instead, it must be installed by the user by cloning the GitHub repository.
+
+To download the source code, use `git clone`. Then, add it to
+your Python path with the "local editable install" through `pip`.
+
+```bash
+# Download the source code.
+git clone https://github.com/NREL/flasc.git
+
 # Install into your Python environment
 pip install -e flasc
