Document EVERYTHING!!!

People leave jobs all the time. People get run over by busses or win the lottery. People forget stuff.

It’s important to document things, especially technical things.

code != documentation

Source code explains how things work… it’s simply telling the computer the algorithm you want run. What’s not often mentioned is wider context.

• Why do we want this thing at all?
• What problem does it solve?
• Why don’t we approach this in a different way?
• What are the current constraints? Is there time / business / financial pressure?
• Is this meant to be scalable or an MVP?
• What does this object / table represent?

Use comments and documentation widely to make it easier for the next person - often you.
