+If it's useful outside http4s.org, it probably should be pushed further upstream into [sbt-spiewak](https://github.com/djspiewak/sbt-spiewak/).

 Triggers automatically.  Use on all http4s modules.
 
-* Sets the organization to `org.http4s`
-* Sets `-Ybackend-parallelism` compiler option
-* Sets an appropriate `-doc-source-url` for your Scaladoc
+* Activates the sensible defaults of [sbt-spiewak](https://github.com/djspiewak/sbt-spiewak/)
+* Sets the organization info
 * Enables automated SPDX license headers with appropriate years
-* Enables [scalafmt](https://scalameta.org/scalafmt/)
-* Enables [MiMa](https://github.com/lightbend/mima) checks for binary compatibility via [sbt-mima-version-check](https://christopherdavenport.github.io/sbt-mima-version-check/)
 * Enables [sbt-github-actions](https://github.com/djspiewak/sbt-github-actions) with settings appropriate to our workflow

 Use on example projects that require ALPN support.
 
 * Sets up `-Xbootclasspath` for [ALPN](https://www.eclipse.org/jetty/documentation/current/alpn-chapter.html). Useful primarily for example projects.

-### `CompileTimePlugin`

-Enable with `enablePlugins(CompileTimePlugin)`.
-Mostly useful to support other plugins.

-* Sets up a `CompileTime` SBT configuration for libraries that exist at compile time, but not runtime.
-
-### `JavaPlugin`
-
-Enable with `enablePlugins(JavaPlugin)`.
-
-* Turns on `-Xlint:all` warnings
-* Enables [sbt-java-formatter](https://github.com/sbt/sbt-java-formatter)
-
-### `PrivateProjectPlugin`
-
-Enable with `enablePlugins(PrivateProjectPlugin)`.
-Use on examples, benchmarks, docs, and other projects that should not be published.
-
-* Skips publishing
-* Disables MiMa checks.
-
-### `SilencerPlugin`
-
-Enable with `enablePlugins(SilencerPlugin)`
-
-* Adds the [silencer](https://github.com/ghik/silencer) compiler plugin to suppress warnings.
-* Adds the supporting library to `CompileTime` and `Test` scopes, so it doesn't leave a trace in production.
-* Disabled automatically in Dotty
