+	We use the text document content provider API to show the left side for diff view by creating a virtual document for the original content. This makes it readonly so users know to edit the right side if they want to keep their changes.
 
 	- This API allows you to create readonly documents in VSCode from arbitrary sources, and works by claiming an uri-scheme for which your provider then returns text contents. The scheme must be provided when registering a provider and cannot change afterwards.
 	- Note how the provider doesn't create uris for virtual documents - its role is to provide contents given such an uri. In return, content providers are wired into the open document logic so that providers are always considered.
