+# Firebase
+
+:::info
+This page explains the steps you need to follow to set up the Firebase
+connection in Automatisch. If any of the steps are outdated, please let us know!
+:::
+
+1. Go to the [Google Cloud Console](https://console.cloud.google.com) to create a project.
+2. Click on the project drop-down menu at the top of the page, and click on the **New Project** button.
+3. Enter a name for your project and click on the **Create** button.
+4. Go to [API Library](https://console.cloud.google.com/apis/library) in Google Cloud console.
+5. Search for **Cloud Firestore API** in the search bar and click on it.
+6. Click on the **Enable** button to enable the API.
+7. Repeat steps 5 and 6 for the **Firebase Realtime Database API and People API**
+8. Go to [OAuth consent screen](https://console.cloud.google.com/apis/credentials/consent) in Google Cloud console.
+9. Select **External** here for starting your app in testing mode at first. Click on the **Create** button.
+10. Fill **App Name**, **User Support Email**, and **Developer Contact Information**. Click on the **Save and Continue** button.
+11. Skip adding or removing scopes and click on the **Save and Continue** button.
+12. Click on the **Add Users** button and add a test email because only test users can access the app while publishing status is set to "Testing".
+13. Click on the **Save and Continue** button and now you have configured the consent screen.
+14. Go to [Credentials](https://console.cloud.google.com/apis/credentials) in Google Cloud console.
+15. Click on the **Create Credentials** button and select the **OAuth client ID** option.
+16. Select the application type as **Web application** and fill the **Name** field.
+17. Copy **OAuth Redirect URL** from Automatisch to **Authorized redirect URIs** field, and click on the **Create** button.
+18. Copy the **Your Client ID** value from the following popup to the `Client ID` field on Automatisch.
+19. Copy the **Your Client Secret** value from the following popup to the `Client Secret` field on Automatisch.
+20. Login to your [Firebase account](https://firebase.google.com/) and go to your project (please create a new project if you don't already have one).
+21. Click on the gear icon next to **Project Overview** and go to **Project settings**.
+22. Copy the **Project ID** value to the `Project ID` field on Automatisch.
+23. Click **Submit** button on Automatisch.
+24. Congrats! Start using your new Firebase connection within the flows.
