 # Requirements
 - Python `>=3.6.10,<3.9`. We currently use `3.8`. For more info, see the [Cloud Composer version list](https://cloud.google.com/composer/docs/concepts/versioning/composer-versions).
-- Familiarity with [Apache Airflow](https://airflow.apache.org/docs/apache-airflow/1.10.15/concepts.html) (>=v1.10.15)
+- Familiarity with [Apache Airflow](https://airflow.apache.org/docs/apache-airflow/stable/concepts/index.html) (>=v2.1)
 - [pipenv](https://pipenv-fork.readthedocs.io/en/latest/install.html#installing-pipenv) for creating similar Python environments via `Pipfile.lock`
 - [gcloud](https://cloud.google.com/sdk/gcloud) command-line tool with Google Cloud Platform credentials configured. Instructions can be found [here](https://cloud.google.com/sdk/docs/initializing).
 - [Terraform](https://learn.hashicorp.com/tutorials/terraform/install-cli) `>=v0.15.1`
-- [Google Cloud Composer](https://cloud.google.com/composer/docs/concepts/overview) environment running [Apache Airflow](https://airflow.apache.org/docs/apache-airflow/1.10.15/concepts.html) `>=v1.10.15,<2.0`. To create a new Cloud Composer environment, see [this guide](https://cloud.google.com/composer/docs/how-to/managing/creating).
