Ghost is completely open source software built almost entirely by volunteer contributors who use it every day.
The best part about structuring a software project this way is that not only does everyone get to own the source code without restriction, but as people all over the world help to improve it: Everyone benefits.
Development guide
If you're a developer looking to help, but you're not sure where to begin: Check out the good first issue label on GitHub, which contains small pieces of work that have been specifically flagged as being friendly to new contributors.
Or, if you're looking for something a little more challenging to sink your teeth into, there's a broader help wanted label encompassing issues which need some love.
When you're ready, check out the full Ghost Contributing Guide for detailed instructions about how to hack on Ghost Core and send changes upstream.
Other ways to help
The primary way to contribute to Ghost is by writing code, but if you're not a developer there are still ways you can help. We always need help with:
- Helping our Ghost users on the forum
- Creating tutorials and integration guides
- Improving our documentation (what you're reading now!)
- Testing and quality assurance
- Hosting local events or meetups
- Promoting Ghost to others
There are lots of ways to make discovering and using Ghost a better experience.
