-Working days
+This repo is set up with three GitHub Actions:
 
-Start date and end date
+## Deploy-PR
+
+1. This action runs *automatically* when any commit is pushed to a PR.
+1. Each PR will create its own deployment "environment".
+
+## Destroy-PR
+
+1. This action runs *automatically* when any PR is closed.
+1. It tears down the PR's deployed environment.
+
+## Deploy
+
+1. This action runs *automatically* on any commit to `main`.
+1. It performs a new deploy to the existing `main` environment.
+
+# Deployment Info
+
+## Where is the app deployed?
+
+The apps get deployed to the Bitovi AWS instance **jira-integrations**.
+
+The Action creates an EC2 VM, installs docker on it, and then launches the application using `docker-compose`.
+
+The public URL of the application is displayed in the Summary tab of an Action's run.
+
+# Contact
+
+For application code questions, please raise an issue in this repo.
+
+Questions or comments about the app's deployment/operations can be aimed at the [devops team](mailto:[email protected])!
