Migrating from ghost to gitbased blog

I enjoy writing although this blog shows not that much considering how often a new post is put out. Apart from ‘LIFE’ taking up so much time , finding time to write is low down on the priority of things, but I would like to post more frequently and to do this im going to need a way to make it easier to post just using markdown and static websites. On top of this, the version of Ghost I was running is giving me warnings now as its out of date and wants an update but this involves backing up everything and recreating the docker to include a seperate database as they are no longer supporting sqlite as a backend. This has given me the final push to migrate.
