Once we have a design, now it's time to hand it off to developers. Thanks to Figma, developers can analyse the project as a whole and get the required assets and CSS for the screens.
As this is a open-source project, so I decided to start build the design system and then create the screens and features step by step. So, workflow looks like this: I create a github issue explaining details and providing assets and help the contributors with any questions. Then I constantly approve the issues for user interface and designs, this is how, it's going so far.
