## Get started in three steps

<Steps>
  <Step title="Create an account">
    Sign up at [nxtdev.xyz](https://nxtdev.xyz) using your email or GitHub. You'll need to link your GitHub account before you can claim a subdomain.
  </Step>

  <Step title="Claim your subdomain">
    From the dashboard, choose a base label — for example, `alice` gives you `alice.nxtdev.xyz`. You can claim up to 2 subdomains on the free tier.
  </Step>

  <Step title="Add DNS records">
    Add a `CNAME` pointing to your Vercel, Netlify, or Render deployment, an `A` record for your VPS, or any other supported record type. Your subdomain goes live immediately.
  </Step>
