-      If this is the first time you try to share a Step you should
-      first call: $ bitrise share
-      This will print you a guide, and information about how Step sharing
-      works. Please read it at least once!
-      As noted in the Step sharing guide you'll have to fork the
-      StepLib you want to share this step into. Once you're done with forking
-      the repository you should set your own fork's git clone URL
-      in the `.bitrise.secrets.yml` file, or here in the `envs` section,
-      as the value of the `MY_STEPLIB_REPO_FORK_GIT_URL` environment.
-      You're now ready to share this Step, just make sure that
-      the `STEP_ID_IN_STEPLIB` and `STEP_GIT_VERION_TAG_TO_SHARE`
-      environments are set to the desired values!
-      To share this Step into a StepLib you can just run: $ bitrise run share-this-step
-      Once it finishes the only thing left is to actually create a Pull Request,
-      the way described in the guide printed at the end of the process.
