This is a documentation file for a simple chat application built using HTML, CSS, and Vanilla JavaScript. The chat app utilizes Firebase for authentication and real-time database functionality.

Before getting started, ensure you have the following:

1. A code editor (e.g., Visual Studio Code, Sublime Text).
2. A Firebase account. If you don't have one, you can create a free account at Firebase.

Follow the steps below to set up your Firebase account, including authentication and real-time database configuration:

1. Go to the Firebase Console and sign in using your Google account.

2. Click on the "Create a project" button and provide a name for your project.

3. Once the project is created, you'll be redirected to the project dashboard.

4. Enable Authentication:

   • Click on the "Authentication" tab in the left sidebar.
   • Choose the "Get started" button under "Sign-in method."
   • Enable the desired sign-in methods (e.g., Email/Password, Google, etc.) and follow the provided instructions to configure them.

5. Enable Realtime Database:

   • Click on the "Realtime Database" tab in the left sidebar.
   • Choose "Create database" and select the "Start in test mode" option (for simplicity).
   • Click on "Enable" to create your database.

To use the chat app:

1. Clone or download the project files to your local machine.

2. Open the project folder in your preferred code editor.

3. In the project files, locate the firebase.js file.

4. Replace the placeholder values in the firebase.js file with your Firebase project's configuration details. You can find these details in the Firebase console under "Project settings" > "Your apps" > "Firebase SDK snippet" > "Config".

5. Open the index.html file in a web browser.
