0. Read the <link>FAQ</link>. Other *mandatory* reading follows at the bottom of these rules. 

1. Google first, ask second. You must work through the Rubber Duck process <i>before</i> asking questions in-channel.

2. This is a volunteer-staffed channel. The time of the volunteers is worth at *least* as much as your time. We are not your employees or your servants. Clean your own room, do your own homework, write your own code, and don't forget to say "Thank you" for the help.

3. The phrase "doesn't work" isn't allowed. Prepare to explain the problem without links to Stack Overflow.

4. Show your code. We don't care about your NDAs. If you don't want to show your code, go pay a consultant. We may ask you to create a minimal project that demonstrates your issue.  Save time by doing so before entering the channel.
