It's seamless. I've been using it for the past 6 months for almost all of my coding. The windows build is brand new and still has some problems, but assuming you're using *nix/mac, you won't have any issues.

Honestly the GitHub repo explains about everything. I check in on r/neovim, as the main contributor posts there often and helps people with problems/questions (I mostly just like reading about the new stuff their doing on the subreddit).
