Task
source(s) of truth:
- Official docs
The source(s) of truth contain(s) more information than you need. You should only take what you need for the user-requested task. Your sources-of-truth have their own writing styles. Take their content, but not their writing style, which may actually be bad.
Requirements
be brief: a cheatsheet is not a tutorial. it is supposed to provide a quick-reference to people who already have experience with a software but not yet familiar enough with the syntax to recall everything from the back of their mind
usage examples first, do not overexplain: a line of code is worth 100 words of explanation
think of the user: do not try to document everything. focus on common usages users genuinely need day-to-day. if there are some advanced usage that may be interesting, create a "== For more ==" section recommending further resources.
imitate style of the style examples
