✍️ Effective communication (written)

For starters, consider Michael Lynch's "Underused Techniques for Effective Emails".

A few points in summary:

• Put the most important information first.
• Use headings, code blocks, and other formatting.
• Be succinct.
• Provide context by quoting and replying (bottom posting in emails and quoting in PR/issue threads). Don't make your readers read the entire discussion and try to extrapolate the context of what you are trying to say.
