Aside from HackMD which was mentioned, another good one is StackEdit. Syncs right up to your Google Drive if you want it to and all your docs can be stored there, in the magical cloud! Straightforward and free, oh and the best part for you, you can customize the keyboard shortcuts so VIM it up~!
Just a coder and a dad. I love my family and I love to code!!!! started coding at 11, so I have 25 years under my belt. Still love learning about it every day. Black lives matter!
