On the other hand, factoring in employee cost of living allows for the take home pay of each employee to be relatively similar.

What is your system for keeping all of these notes. Do you just have a git repo for everything?

Not OP, but I've been keeping a "journal" repo for the last 4 months. There's a single dev.md file in there, where I separate each entry with "---". Whenever I encounter an issue or learn something new, I document it for later reference.

It honestly depends on what it is - sometimes in the repository, for a wiki it’s stored in the wiki itself, otherwise it might be as simple as a text file in a web directory.

I do same and keep everything in Evernote organized in subfolders and tagged. Quick to find and helps 100% when it's time to rebuild/setup a server.
