 To help you get your feet wet and get you familiar with our contribution process, we have a list of [good first issues](https://github.com/mui-org/material-ui/issues?q=is:open+is:issue+label:"good+first+issue") that contain changes that have a relatively limited scope. This label means that there is already a working solution to the issue in the discussion section. Therefore, it is a great place to get started.
-If you didn't find a suitable issue you can also follow [@MuiContrib](https://twitter.com/MuiContrib) which automatically tweets new good first issues.
 
 We also have a list of [good to take issues](https://github.com/mui-org/material-ui/issues?q=is:open+is:issue+label:"good+to+take"). This label is set when there has been already some discussion about the solution and it is clear in which direction to go. These issues are good for developers that want to reduce the chance of going down a rabbit hole.
