To edit documents on GovernorHub, simply download the document you want to modify, make the changes to the downloaded file (for example, in Microsoft Word), then upload the new version.

If you keep the name of the document the same, this will overwrite the document on GovernorHub with the new version.

​Note: if a document is locked, it won't be possible for a non-admin to overwrite it. All documents uploaded by admins are automatically locked.
