Website Purpose

This is a personal portfolio and project showcase website highlighting my work in Computer Science, software development, Data Science, and AI/ML engineering (including projects like CerebrArt and VisionFusion).

Note for reviewers: My root domain (debjit.json) is already registered and active. This PR simply adds a new _dmarc.debjit.json file to establish a DMARC policy (p=none) for my custom domain. This is required to ensure that outgoing custom domain emails sent via Gmail's SMTP servers comply with DMARC alignment and are not rejected by strict receiving mail servers.

Changes:

• Added domains/_dmarc.debjit.json defining a DMARC policy via a TXT record for _dmarc.debjit.is-a.dev.

What's next?

Just follow the steps below and you can start using your domain!

GitHub Pages

1. Navigate to your GitHub Pages repository that you want to connect with your is-a.dev domain.
2. Click on the Settings tab.
3. Click on the Pages link in the sidebar.
4. In the custom domain option, enter the domain you registered.
5. Check the Enforce HTTPS checkbox.
6. Give your domain some time (~24 hours) for the changes to propagate.
7. Enjoy your domain!

Vercel

You may have to verify the domain so that you can successfully add the domain to your Vercel website; if you have done that already, the domain should already be connected! If it hasn't, go to the "Domains" section in your project's dashboard and click on "Refresh" to see if it works. If you need to verify the domain with Vercel then please follow our Vercel guide here.

Cloudflare Pages

Please read this section of our documentation.

Other hosting providers

Just make sure you have added the domain to your website. Try to see if there is a guide for your hosting provider at our documentation to see how you can configure it. It's also a good idea to see your hosting providers' documentation to see how you can add a custom domain.

Webserver (like NGINX, Caddy, Apache and etc.)

You have to add these in your webserver config by yourself. If you don't know how to add a domain to your webserver then either use a different method of hosting your website or search on a search engine on how to use the said webserver.

Need help with your domain? If you have some trouble setting up your domain, please create an issue or ask in the Discord server and we will try and help you as soon as possible!
