Step 1 — Create a free Firebase project
Go to
console.firebase.google.com → Add project → name it "kad-admin-hub" → disable Google Analytics → Create project.
Step 2 — Enable Realtime Database
In the left sidebar: Build → Realtime Database → Create database → choose "Start in test mode" → Done.
Step 3 — Get your config keys
Click the gear icon (⚙) → Project settings → scroll to "Your apps" → click the web icon (</>) → register app → copy the
firebaseConfig object → paste each value into the FIREBASE_CONFIG at the top of this HTML file → save and reopen.
That's it. Both you and Sam open the same file from a shared location (Egnyte, email, USB) and all changes sync instantly.
