How to Create a Subdomain on is-a.dev

1. Go to this link.
2. Add a file by clicking on "Create new file." Then paste the JSON below and name the file mrtemp70.json. This will create the subdomain mrtemp70.is-a.dev. (The JSON format is just a template; the name does not affect the format.)

{
  "owner": {
    "username": "mrtemp70",
    "email": "mrtemp70@gmail.com"
  },
  "record": {
    "CNAME": "mrtemp70.github.io"
  }
}
