-# http-flask
+# HTTP Flask Example
+
+This sample demonstrates how to expose a Flask app as a single Cloud Function. The Flask app provides a simple CRUD interface for "widgets" stored in the Realtime Database.
+
+## Functions Code
+
+See file [functions/main.py](functions/main.py) for the code.
+
+The sample creates a Flask app and defines two routes:
+
+- `GET /widgets` and `GET /widgets/<id>`: These routes retrieve a list of all widgets or a single widget by its ID from the Realtime Database.
+- `POST /widgets`: This route adds a new widget to the Realtime Database.
+
+The entire Flask app is then exposed as a single Cloud Function called `httpsflaskexample` using `@https_fn.on_request()`.
+
+## Trigger rules
+
+The `httpsflaskexample` function is triggered by an HTTP request.
+
+## Deploy and test
+
+To deploy and test the sample:
+
+1. Create a Firebase project on the [Firebase Console](https://console.firebase.google.com).
+2. Get the code, for instance using `git clone https://github.com/firebase/functions-samples`
+3. Enter the correct directory `cd functions-samples/Python/http-flask`
+4. Set up the CLI to use your Firebase project using `firebase use --add` and select your Firebase project.
+5. Deploy your project's code using `firebase deploy`.
+6. Use a tool like `curl` to test the function:
+   - **Add a widget:** `curl -X POST -d "My new widget" https://us-central1-YOUR_PROJECT_ID.cloudfunctions.net/httpsflaskexample/widgets`
+   - **Get all widgets:** `curl https://us-central1-YOUR_PROJECT_ID.cloudfunctions.net/httpsflaskexample/widgets`
+   - **Get a specific widget:** `curl https://us-central1-YOUR_PROJECT_ID.cloudfunctions.net/httpsflaskexample/widgets/WIDGET_ID`

-# post-signup-event
+# Post Sign-up Event with Google Calendar
+
+This sample demonstrates how to use an [Auth blocking function](https://firebase.google.com/docs/functions/auth-blocking-events) to save a user's Google OAuth2 access token to Firestore upon sign-up. It then uses a [task queue](https://firebase.google.com/docs/functions/task-functions) to schedule a Cloud Function that uses this token to create a Google Calendar event for the user.
+
+## Functions Code
+
+See file [functions/main.py](functions/main.py) for the code.
+
+The function `savegoogletoken` is an Auth blocking function that triggers before a user is created. If the user is signing up with Google, it saves their OAuth2 access token to a `user_info` collection in Firestore. It then creates a task to call the `scheduleonboarding` function.
+
+The `scheduleonboarding` function is a task queue function that retrieves the user's access token from Firestore, creates a new event on their primary Google Calendar, and then deletes the access token from Firestore.
+
+## Trigger rules
+
+- The `savegoogletoken` function is triggered by `beforeUserCreated` Auth blocking event.
+- The `scheduleonboarding` function is triggered by a task queue.
+
+## Deploy and test
+
+To deploy and test the sample:
+
+1. Create a Firebase project on the [Firebase Console](https://console.firebase.google.com).
+2. Enable the **Google Calendar API** for your project in the [Google Cloud Console](https://console.cloud.google.com/apis/library/calendar-json.googleapis.com).
+3. Enable blocking functions for your project in the Firebase console:
+   - Go to the **Authentication** > **Settings** page.
+   - In the **Blocking functions** section, select **Before user creation (beforeCreate)** from the dropdown menu.
+   - Ensure that **Enable credential pass-through** is checked.
+4. Get the code, for instance using `git clone https://github.com/firebase/functions-samples`
+5. Enter the correct directory `cd functions-samples/Python/post-signup-event`
+6. Set up the CLI to use your Firebase project using `firebase use --add` and select your Firebase project.
+7. Deploy your project's code using `firebase deploy`.
+8. Sign up for your app using a Google account.
+9. After a minute, check your Google Calendar for a new "Onboarding with ExampleCo" event.
