Firebase Firestore Standard

This is your go-to resource when you need to get Firestore Standard Edition running properly. It walks you through the actual provisioning steps, shows you how to write security rules that don't accidentally expose your data, and covers the web SDK integration with real examples. The security rules section is honestly the most valuable part since those can be tricky to get right. It also includes the indexing guidance you'll need when your queries start hitting performance issues. Skip this if you're already comfortable with Firestore, but it's solid for getting set up correctly the first time.
