 When the user requests the user dashboard to start a workspace, the user dashboard executes this sequence of actions:
 
-. Collects the devfile from the xref:devfile-registries.adoc[], when the user is creating a workspace from a code sample.
 . Sends the repository URL to xref:che-server.adoc[] and expects a devfile in return, when the user is creating a workspace from a remote devfile.
 . Reads the devfile describing the workspace.
 . Collects the additional metadata from the xref:plugin-registry.adoc[].
