# Setting up is-a.dev with Railway

# Getting the CNAME Record

Navigate to the dashboard
Navigate to the project.
Navigate to the service.
Switch to the Settings tab.
Click on + Custom Domain button.
Enter the is-a.dev subdomain you want to use.
Copy the Value field.
For the domain, make the json like this:

{
  "owner": {
    "username": "your-github-username",
    "email": "your-email@example.com"
  },
  "records": {
    "CNAME": "the-value-railway-gave-you"
  }
}

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.

If the PR has been merged, the DNS records will be updated in a few minutes.
If the PR has been merged but the DNS records haven't updated and you have waited 48 hours, open a GitHub issue or a help thread in the is-a.dev Discord server.
