# Creating sub-domain
Step 1. Go to Cronos ID homepage and click “My Domains”.
**Step 2.** Next to the parent domain that you want to create sub-domain for, click “Manage”.
**Step 3.**
(a) If this is your first time creating a sub-domain, click “Approve Sub-domain in wallet” and confirm the transaction approval on your wallet.
(b) Under sub-domain, click “Add”.
**Step 4.** Enter the desired sub-domain name, e.g. john.cronos.cro
{% hint style="info" %}
Please double check as you will not be able to edit or delete the sub-domain created!
{% endhint %}
**Step 5.** Enter the Controller wallet address. Owner of this wallet address will take ownership of this sub-domain.
**Step 6.** Click “Confirm and Next” and confirm the transaction approval on your wallet.
**Step 7.** You have successfully created the sub-domain! You can now view the sub-domain under “My Domains”.
