+This action supports multiple ways of retrieving your Postman collections/environments.
 
-- Your [Postman API key](https://docs.api.getpostman.com/?version=latest#authentication)
-- The collection ID
-- The environment ID
+### Local files
+If you've exported your collection and/or environment to your repo, provide the relative path to where the file sits in your repo (default: `postman_collection.json` / `postman_environment.json`).

+    environment: postman_environment.json
+```          
+
+### Via URL
+If you're collection and/or environment is sitting at a URL accessible to your GitHub action, you can include that directly.

+
+### Via Postman API
+The latest version of your collection and/or environment is available through [Postman's API](https://docs.api.getpostman.com/?version=latest). The API docs contain endpoints that will allow you to retrieve the required IDs. Passing these IDs along with your Postman API key will run Newman in this method. See [Creating and using secrets](https://help.github.com/en/articles/virtual-environments-for-github-actions#creating-and-using-secrets-encrypted-variables) for how to add your Postman API to GitHub securely.
