For anyone interested , here is an introduction to Overleaf, the online, collaborative \LaTeX\ editor.
Good point, I have JabRef but not tex studio installed, so should do that.
I have upgraded my account so should be able to push to github.
I don't do much that is mission critical, just personal documents, my CV etc.
As part of the Labs programme, I want to suggest they include gitlab integration, so we can link to other instances, partly as I maintaining a Debian presentation, so for the Debian people GitHub is depreciated over salsa.gitlab
