 As mentioned above, the `GenerativePlugin` is designed to make it easier to maintain GitHub Actions builds for sbt projects by generating **ci.yml** and **clean.yml** workflow definition files, and then forcibly failing the build if these files ever fall out of step with the build itself. The **ci.yml** workflow, by default, contains both `build` and `publish` jobs, though you will likely need to add extra steps to the `githubWorkflowPublishPreamble` and/or `githubWorkflowEnv` (e.g. decrypting and importing a GPG signing key) in order for publication to *actually* work.
 
-If a `publish` job is not desired, simply set `githubWorkflowPublishTargetBranches` to `Seq()`. By default, `publish` is restricted to run on `master`, and additional restrictions may be configured within the build.
+If a `publish` job is not desired, simply set `githubWorkflowPublishTargetBranches` to `Seq()`. By default, `publish` is restricted to run on `main`, and additional restrictions may be configured within the build.
 
 Ivy, sbt, and Coursier caching are all handled by the generated **ci.yml** by default, as well as standard things like Git checkout, Scala setup (using Olafur's [excellent `setup-scala` action](https://github.com/olafurpg/setup-scala)), and more. The matrix for the `build` job will be generated from `crossScalaVersions` and has additional support for multiple JVMs and OSes. Additionally, compiled artifacts are properly uploaded so that jobs which are dependent on `build` can avoid redundant work (most notably, `publish`). Thus, publication is guaranteed to be based on binary files that were generated *and* tested by the `build` job, rather than re-generated by `publish`. (**NB**: due to what appear to be issues in Zinc, this isn't *quite* working yet; expect it to be fixed in a coming release of sbt-github-actions)
