is the project still active?

It's more or less dead. I had some goals here, but never had the time. Sorry.

Are there instructions anywhere on how to use it?

Unfortunately no.

Has this project been superseded/abandoned in favor of Ktlint and/or Detekt?

PMD has usually sat in a different place in the ecosystem than linters like Ktlint. Detekt may have more rules that are about good code patterns.
