 When you add a new user to your organization, you can associate that user to one or more collections within your organization. Once the user has access to your organization, any items that are placed into that user's associated collections will be available in their vault. When associating a user to a particular collection, you can also decide whether or not that user has write access to logins contained within it. Selecting the **Read Only** option will ensure that the user cannot add, edit, or delete any items within that particular collection (they can just view and use them).

+## Nested collections (sub-collections)
+
+Nested collections work by using a naming convention with the forward slash character (`/`) as a delimiter. For example, if I have collections with the names "Servers" and "Servers/Production", "Production" will be nested as a sub-collection underneath the "Servers" collection.

+{% note %}
+Creating sub-collections is only for display purposes. Collection access and permissions are not inherited by their "child" sub-collections.
