Wiki Editing

Created by: bkmgit

Would be helpful if contributions to the wiki could also be made. This might help with #201. Could this be enabled for this repository, see https://help.github.com/en/github/building-a-strong-community/changing-access-permissions-for-wikis - alternatively, rather than use a wiki, perhaps markdown formatting could be used and the content put in the main git repository to allow for contributions through pull requests.
