Advice on organizing developer events

Developer events, also known as "hack days", "hack weekends" and "hackathons", are meetings of developers to discuss, network and collaborate with other developers, designers, documenters, and others with an interest in software.

If you are organising one of these events, then you may like to read our Engineering Working Group's advice.
