Phase 1: Preparation on GitHub
Before touching your domain provider, you need to tell GitHub which domain to expect.

Open your GitHub repository and go to Settings.

On the left sidebar, click Pages.

Under the Custom domain section, type your domain (e.g., www.yourdomain.com) and click Save.

Note: This creates a CNAME file in your repository automatically.

Phase 2: Configure Your DNS Provider
Now you need to tell the "phonebook" of the internet (your DNS provider like Namecheap, GoDaddy, or Google Domains) to point to GitHub.

1. Set up Apex Domains (example.com)
   To point your main domain to GitHub, you need to add A Records that point to GitHub’s IP addresses. Create four A records with the host @ pointing to:

185.199.108.153

185.199.109.153

185.199.110.153

185.199.111.153

2. Set up Subdomains (www.example.com)
   To make the www version work, add a CNAME record:

Type: CNAME

Host/Name: www

Value/Target: yourusername.github.io (Replace with your actual GitHub URL).

Phase 3: Verification and Security
Once the DNS records are saved, head back to your GitHub repository settings.

Check the status: In the Pages settings, GitHub will show a message saying "DNS check successful" once the changes propagate.

Patience is key here; it can take anywhere from a few minutes to 24 hours.

Enforce HTTPS: Once the DNS is verified, check the box for Enforce HTTPS. This ensures your site is secure and avoids "Not Secure" warnings in browsers.
