Proofreading is something you want to-do quickly and on the fly. If you have docker installed you can download the entire redpen server.
docker pull dai0304/techdoc-redpen
Of course, you’re not interested in running a server. You just want to proof read your document.

alias docker-redpen='docker run -v $(pwd):/redpen -w /redpen --rm -it dai0304/techdoc-redpen'
Start a new terminal and go to your document directory.
Your work directory is mounted into the container. And you are in the shared volume directory.

Apart from internal redpen information, you should get remarks on your text. Unless everything is perfect.
Redpen can read all kinds of formats. Personally I use it on my markdown documentation.
