View source for Create or edit repository

If you want to create a new [[repositories|repository]], you have to enter
* name: should be short and unique
* descirption: this will be displayed on the main page of the repository
* access: default is public read access, while write access can be specified in the [[permissions]]. You can also chose public read and write access, but then anyone can modify or delete files in your repository (this is useful e.g. for sandboxes). For private repositories, both read and write access is regulated by the permissions. 
* source address: here, you can specify the URL of an existing [[git]] or [http://en.wikipedia.org/wiki/Apache_Subversion subversion] repository. Then your new repository will become a [[mirror]] of that repository. If you want a completely fresh repository, leave this field empty.

If you want to edit an existing repository, you can change the first three items. Beware that the repository's permissions are reset if you change its access mode.
