Publishing is when you save a copy of your place to the Roblox servers. This means that it saves your place, and then uploads it to the Roblox servers, where it is stored so others can enjoy your place more easily.
To Publish Your Place:
- Create your place
- While in Studio (Edit Mode), click on Publish to Roblox As from within the File menu
- A new window will pop up, asking you to choose an existing place to overwrite, or create a new place
- Select your option and your place will be uploaded
Note: When creating your place, make sure to save an extra copy on your computer so you can have a back up in case something happens
If you're simply updating a place that has previously been uploaded to Roblox, you can go to File, then click Publish to Roblox.
