# Development¶

GPAW development can be done by anyone! Just take a look at the issue tracker and find something that suits your talents!

The primary source of information is still the Manual and Documentation, but as a developer you might need additional information which can be found here. For example the Code Overview.

As a developer, you should subscribe to the GPAW Mail List. We would also like to encourage you to join our channel for Internet Relay Chat.

Now you are ready to to perfom a Developer installation and start development!

## Development topics¶

When committing significant changes to the code, remember to add a note in the Release notes at the top (development version) - the version to become the next release.

Getting commit access to the GPAW code works the same way as for the ASE project.
