 ## About
 
 App showing estimated flood exposure based on WorldPop and Floodscan.
+
+## Usage
+
+Running the app locally:
+
+1. Install the dependencies with `pip install -r requirements.txt`
+2. Install the local package with `pip install -e .`
+3. Set environment variables `DEV_BLOB_SAS` and `PROD_BLOB_SAS` to the SAS
+token for the blob storage account.
+4. Run the app with `python app.py` for debugging, or
+`gunicorn -w 4 -b 127.0.0.1:8000 app:server` for production.

+## Development
+
+All code is formatted according to black and flake8 guidelines.
+The repo is set-up to use pre-commit.
+Before you start developing in this repository, you will need to run
+
+```shell
+pre-commit install
+```
+
+The `markdownlint` hook will require
+[Ruby](https://www.ruby-lang.org/en/documentation/installation/)
+to be installed on your computer.
+
+You can run all hooks against all your files using
+
+```shell
+pre-commit run --all-files
+```
+
+It is also **strongly** recommended to use `jupytext`
+to convert all Jupyter notebooks (`.ipynb`) to Markdown files (`.md`)
+before committing them into version control. This will make for
+cleaner diffs (and thus easier code reviews) and will ensure that cell outputs aren't
+committed to the repo (which might be problematic if working with sensitive data).
