The simplest way to install CoffeePot is to download the latest release zip file from https://github.com/nineml/coffeepot/releases/latest. Unzipping that somewhere on your system will result in a directory that contains a jar file and a few ancillary files. You can run CoffeePot directly from the jar file.

You can also get CoffeePot from Maven with the following coordinates:

<dependency>
  <groupId>org.nineml</groupId>
  <artifactId>coffeepot</artifactId>
  <version></version>
</dependency>

For more details about incorporating CoffeePot into a project of your own, see the HOWTO repository.
