Workgroups are formed by community members who join forces to achieve a common goal. They have different structures and goals. On this page we list some of the more active workgroups and some tips to get you started, if you wish to contribute to any of them.
This workgroup unites Monero developers working on the wallets and daemon maintained by the Core Team. It consists of two main parts: the CLI team and the GUI team. These teams coordinate using two different chatrooms.
It's always a good idea to join the chatroom and talk directly with the members of the workgroup, but if you prefer to get started by yourself, take a look at the readme in the GitHub repository. It contains step by step instructions to edit every single part of this website.
Contact the workgroup on the chatroom or open an issue on the GitHub repository. You can also start translating immediately using the Weblate platform. Just make sure to read the guide for translators first.
As the name suggests, the Monero Research Lab is the workgroup focused on Monero-related research. It's formed by scientists finding ways to improve Monero's protocol and features. Most of the protocol improvements that make Monero amazing, like CLSAG and @Bulletproofs, are the result of the efforts of this workgroup.
