 HiGHS is open source for distribution rather than contribution. This applies particularly to the core C++ code of the solvers. However, there is definitely scope for external contribution to interfaces and documentation. If you want to contribute in this way, please open an issue before making a pull request, since pull requests to the HiGHS solvers will not normally be accepted. 
 
-Please note that any pull requests to HiGHS must be made to the `latest` branch, so that full testing can take place befor updating `master`. This ensures that `master` is always good to be downloaded by users.
