# Editing your realm/extension

If you want to update your realm, all you need to is rebuild your level (described in [Quick Start](/metaverse-creator-manual/05OugTkVduc9hQ7Ajmqc/quick-start.md)), go to [Dreem webiste](https://dreem.xyz/#/), visit your profile by clicking the avatar located in top-right corner

Select the realm/extension you want to update and click on gear icon to make changes. You can also use quick actions (publish and delete) located on every level tab.

When you modify a realm/extension, you'll see a popup similar to the one when you were uploading it. You don't need to specify all the informations, only the one you want to change (but uploading only .dreemworld or .dreemworld.data is not possible, when you decide to update these, you have to specify both files as they're linked).
