Document Your Process

If you want to debug faster and avoid getting stuck, one of the best habits you can build is writing everything down. Here are the core points from the lesson:

• Document your hypotheses, tests, and findings continuously during debugging to create clarity, reduce mistakes, and avoid repeating the same experiments
• Writing things down makes it easier for teammates to jump in, share context quickly, and collaborate effectively when tackling complex bugs
• Even when debugging alone, written notes help you stay organized, maintain momentum, and prevent morale-killing mistakes like redoing work you already tried
• Good documentation habits (like clear pull requests and linking to issues) allow future debuggers to “time travel” and understand why code was written a certain way
• Strong debugging cultures start with individuals — write as you debug today, and your future self (and team) will thank you
