4. Switch to the **Settings** tab.
5. Click on **+ Custom Domain** button.
6. Enter the `is-a.dev` subdomain you want to use.
7. Copy the **Value** field.
8. For the domain, make the json like this:
```json
{
  "owner": {
    "username": "your-github-username",
    "email": "your-email@example.com"
  },

    "CNAME": "the-value-railway-gave-you"
  }
}
```
9. After you have made the file, you should make a pull request.
!!!
**Adding the website preview is mandatory**, since the CNAME value Railway gives you doesn't actually show you the website you are running.
