+# Airflow Dev Shell
+
+This is a small flake template for experimenting with [Apache Airflow](https://airflow.apache.org/)
+(version 2.7.3). [direnv](https://direnv.net/) can be used to a launch a dev
+shell upon entering this directory (refer to `.envrc`). Otherwise run via:
+```bash
+$ nix develop
+```
+Once your environment has booted, you can get started with the UI by running:
+```bash
+$ airflow standalone
+```
+The webserver lives at `localhost:8080` by default. The username is `admin` and
+the generated password can be found by running:
+```bash
+$ cat airflow/standalone_admin_password.txt
+```
+or looking through the console output.
+
+A basic DAG is included in the top-level `dags/` directory. Airflow discovers
+this DAG with the help of the `AIRFLOW__CORE__DAGS_FOLDER` environment variable,
+set within the nix dev shell.
