- Find an undocumented method and write a ScalaDoc entry for it. See [Arrow.scala](https://github.com/typelevel/cats/blob/main/core/src/main/scala/cats/arrow/Arrow.scala) for some examples of ScalaDoc entries that use [sbt-doctest](https://github.com/tkawachi/sbt-doctest).
- Find an [open issue](https://github.com/typelevel/cats/issues?q=is%3Aopen+is%3Aissue+label%3Aready), leave a comment on it to let people know you are working on it, and submit a pull request.

Ops classes should be marked final and extend AnyVal, to take full advantage of inlining and prevent unnecessary allocations.

for example with Simulacrum.

In Scala, when there are multiple type parameters in a function, either scalac infers all type parameters or the user has to
specify all of them. Often we have functions where there are one or more types that are inferable but not all of them. For example, there is helper function in `OptionT` that creates an `OptionT[F, A]` from an `A`. It could be written as:
```scala mdoc:silent

You probably noticed that there is a `val dummy: Boolean` in the `PurePartiallyApplied` class. This is a trick we used
to make this intermediate class a [Value Class](http://docs.scala-lang.org/overviews/core/value-classes.html) so that there is no cost of allocation, i.e. at runtime, it doesn't create an instance of `PurePartiallyApplied`. We also hide this partially applied class by making it package private and placing it inside an object.

When there are multiple instances provided implicitly, if the type class of them are in the same inheritance hierarchy,
the instances need to be separated out into different abstract class/traits so that they don't conflict with each other. The names of these abstract classes/traits should be numbered with a priority with 0 being the highest priority. The abstract classes/trait
with higher priority inherits from the ones with lower priority. The most specific (whose type class is the lowest in the hierarchy) instance should be placed in the abstract class/ trait with the highest priority. Here is an example.
