If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install damm32

Damm32.checksum("abc")
=> "g"

Damm32.add_checksum("abc")
=> "abcg"

Damm32.valid?("abcg")
=> true

Damm32.valid?("abc0")
=> false

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
