Found something wrong?
Corrections are the most useful thing you can send. Every post here is checked against primary sources before it ships, but versions move, prices change, and I get things wrong. If a command no longer works, a number is stale, or a claim doesn’t hold up, tell me which post and what you saw — I’d rather fix it than leave it.
Open an issue or start a discussion on GitHub. That is the fastest route and it leaves a public record, so the next reader benefits too.
Questions about a post
If something in a guide didn’t work on your setup, include your OS, the exact command, and the error text. Those three things usually make the answer obvious; without them I’m guessing.
Permissions and reuse
Short quotes with a link back are always fine, no need to ask. Republishing a whole post is not — see the Terms for the details. For anything else, ask first.
