Here are some examples:

• Root README is missing machine learning category of samples
• README in algorithms is missing repeat-until-success and sudoku-grover
• [README in diagnostics](https://github.com/microsoft/Quantum/blob/main/samples/diagnostics/RE

Contribution guide lists the types of things one could contribute, but doesn't go into details on the moving pieces that go into doing each of those things. It makes sense to add a bit more guidance on this:

To get this codebase up to standard, we need to add type hints. At the very least, perhaps we should start insisting that all new code has type hints added, but moreover we need to add typing to the code that currently exists.

This is a pretty large project, but luckily it can be done incrementally - I believe at this point it's a stretch goal for v1, if anyone wants to help it would be much ap

Running travis lint gives a bunch of warning. Like for instance, sudo : required is no longer needed, and Travis migrated to a new architecture. So the travis.yml file needs to be updated.

For example, pylint would have caught ProjectQ-Framework/ProjectQ#19 via an undefined variable warning.

Requested Feature

LinearEqualityToPenalty converter only accepts a single scalar input as penalty factor. Better results can be usually obtained by applying higher penalty factors to broken constraints. This requires LinearEqualityToPenalty to accept a list of penalty terms as input, including separate penalty factor for each constraint. If user provides none or a single value for penalty, the
