+2. Follow the [installation instructions](https://code.visualstudio.com/docs/devcontainers/containers#_installation)

 The dev Container is configured in the `.devcontainer` directory:
 
 - `docker-compose.yml` file in this directory extends the `docker-compose.yml` in the root directory.
 - `devcontainer.json` configures the integrations with Visual Studio Code, such as the IDE extensions and settings in the `vscode` directory.

 ### Configure Environment Variables
 
-- If you are an official Chayn volunteer: please get in touch with the team for access to our environment variables.
-
-- If you are an open-source contributor: create a new `.env` file and populate it with the following variables.
-
-**The Firebase tokens are required for running locally, the Simplybook tokens are required for testing, and all other variables are optional.**
-
-You will need to gather your own Firebase tokens. Here are resources to get started:
-
-- [Firebase Docs: Auth](https://firebase.google.com/docs/auth)
-- [Firebase Docs: API Keys](https://firebase.google.com/docs/projects/api-keys)
-- [Firebase Docs: Projects](https://firebase.google.com/docs/projects/learn-more#project-identifiers)
-- [Firebase Docs: Get Started with Fundamentals](https://firebase.google.com/docs/guides)
+Create a new `.env` file and populate it with the variables below. Note that only the Firebase and Simplybook tokens are required.
+To configure the Firebase variables, first [create a Firebase project in the Firebase console](https://firebase.google.com/) (Google account required). 
+Next, follow [these directions](https://firebase.google.com/docs/cloud-messaging/auth-server#provide-credentials-manually) to generate a private key file in JSON format. 
+These will generate all the required Firebase variables.
 
 The Simplybook variables can be mocked data, meaning **you do not need to use real Simplybook variables, simply copy paste the values given below.**
 If you acquire real Simplybook environment variables, use the same format given below.
