I do. Not code, but a mix of a custom cheatsheet, notes and blog..

It's not that elaborate, but I found it the best solution for cross platform and cross-location.

I can access it everywhere and edit it from everywhere, where I have a IDE available.

I like a 1 for all solution more then specific tools, like the specialized cheatsheet CLI tools - it gets messy after a while...

I use https://docsify.js.org/#/ at https://slashlog.org/#/
