write-the-readme.txt
Here is my project: <paste the main files or describe the structure>

Write the README. Keep it short and put it in this order:
1. What this is and who it's for. Two sentences.
2. How to run it locally — every command, in order, from a clean clone.
3. The environment variables it needs and what each is for.
4. How to deploy it.
5. The three things a newcomer would get wrong.

No badges, no table of contents, no "contributions welcome" boilerplate.

Point 5 is the only part nobody else can write. It is also the part you will need most when you come back to this.
