+# Adding a new azd environment variable
+
+An azd environment variable is stored by the azd CLI for each environment. It is passed to the "azd up" command and can configure both provisioning options and application settings.
+When adding new azd environment variables, update:
+
+1. infra/main.parameters.json : Add the new parameter with a Bicep-friendly variable name and map to the new environment variable
+1. infra/main.bicep: Add the new Bicep parameter at the top, and add it to the `appEnvVariables` object
+1. azure.yaml: Add the new environment variable under pipeline config section
+1. .azdo/pipelines/azure-dev.yml: Add the new environment variable under `env` section
+1. .github/workflows/azure-dev.yml: Add the new environment variable under `env` section
+
+# Adding a new setting to "Developer Settings" in RAG app

+When adding a new developer setting, update:
+
+* frontend:

+  * app/frontend/src/components/Settings.tsx : Add a UI element for the setting
+  * app/frontend/src/locales/*/translations.json: Add a translation for the setting label/tooltip for all languages

+  * app/backend/approaches/retrievethenread.py : Retrieve from overrides parameter
+  * app/backend/app.py: Some settings may need to sent down in the /config route.
+
+# When adding tests for a new feature:
+
+All tests are in the `tests` folder and use the pytest framework.
+There are three styles of tests:
+
+* e2e tests: These use playwright to run the app in a browser and test the UI end-to-end. They are in e2e.py and they mock the backend using the snapshots from the app tests.
+* app integration tests: Mostly in test_app.py, these test the app's API endpoints and use mocks for services like Azure OpenAI and Azure Search.
+* unit tests: The rest of the tests are unit tests that test individual functions and methods. They are in test_*.py files.
+
+When adding a new feature, add tests for it in the appropriate file.
+If the feature is a UI element, add an e2e test for it.
+If it is an API endpoint, add an app integration test for it.
+If it is a function or method, add a unit test for it.
+Use mocks from conftest.py to mock external services.
+
+When you're running tests, make sure you activate the .venv virtual environment first:
+
+```bash
+source .venv/bin/activate
+```
