About a month ago, our CEO Brennan wrote an article on Hacker Noon: 12 Manager ReadMes from Silicon Valley’s Top Tech Companies. And…it kind of went viral.

So, I started digging through the interwebs and found as many of these manager readmes as I could (special thanks to managerreadme.com and Richard McLean). I had to stop myself at 49 (that’s a cool number right?), because the concept is spreading like wildfire, specifically in the tech industry, and more are being shared every day.

For those of you asking yourself, “what the heck are manager readmes?” – here’s a quick download:

Manager readmes are user manuals written by managers on their management style, philosophies, expectations, communication preferences, and more. It’s like a “how to guide” for employees getting to know – and working for – their bosses.
