Writing and updating documentation pays dividends for you and for your team.

Signals for when to write documentation include:

• Explaining the same thing again and again
• Spending a lot of time figuring something out
• Misleading or confusing documentation - you can update it!

I often write documentation with future me as the primary audience, but in such a way that it benefits others too.

Here are a few examples of documentation work:

• I was reading a document at work about how to authenticate with a service and found several points confusing; once I figured it out, I updated the document. Others said it was an improvement.
• I lead a medical mission trip and kept a running doc of all the things I wish I’d known; I plan to turn this into a guide for future team leaders (including future me).
