+## Deploying to QA environment
+This repo has a [Github Action workflow](.github/workflows/qa.yml) that allows DCP engineers to deploy feature branches to a QA environment hosted at https://qa-capitalplanning.nycplanningdigital.com/. This can be helpful for getting feedback from QA and Design staff on branches _before_ they are merged into `main`. Because this environment is shared by the team, it is recommended that you confirm with other engineers that they are not using it before deploying.
+
+To deploy to this environment:
+1. Click the "Actions" tab at the top of the page for this repo
+2. Select the "Deploy to quality assurance" workflow from the list on the left side of the page
+3. Click "Run workflow"
+4. Select the branch you want to deploy and click "Run workflow"
+
+Once the workflow runs successfully, your branch should be deployed at https://qa-capitalplanning.nycplanningdigital.com/.
