 # How Do I Use This?
 
-## With Beaker 3.x
+You will need to include beaker-puppet alongside Beaker in your Gemfile or project.gemspec. E.g.
 
-This library is included as a dependency of Beaker 3.x versions and is automatically included, so there's nothing to do.
-
-## With Beaker 4.x
-
-As of Version 1.0 of `beaker-puppet`, the minimum supported version of beaker is Version 4.0. If you use `ENV['BEAKER_VERSION']`, you will have to ensure that this is compatible, and that if you are using a local Git repository it is up to date.
-
-As of beaker 4.0, all hypervisor and DSL extension libraries have been removed and are no longer dependencies. In order to use a specific hypervisor or DSL extension library in your project, you will need to include them alongside Beaker in your Gemfile or project.gemspec. E.g.
-
-~~~ruby
+```ruby
 # Gemfile
 gem 'beaker', '~>4.0'
 gem 'beaker-puppet', '~>1.0'
 # project.gemspec
 s.add_runtime_dependency 'beaker', '~>4.0'
 s.add_runtime_dependency 'beaker-puppet', '~>1.0'
-~~~
-
-For DSL Extension Libraries, you must also ensure that you `require` the library in your test files. You can do this manually in individual test files or in a test helper (if you have one). You can [use `Bundler.require()`](https://bundler.io/v1.16/guides/groups.html) to require the library automatically.
-
-### Right Now? (beaker 3.x)
-
-At this point, beaker-puppet is included in beaker, so you don't have to _do_
-anything to get the methods in this library.
-
-You can use these methods in a test by referencing them by name without
-qualifications, as they're included in the beaker DSL by default.
-
-### In beaker's Next Major Version? (beaker 4.x)
+```
 
-In beaker's next major version, the requirement for beaker-puppet will be pulled
-from that repo. When that happens, then the usage pattern will change. In order
-to use this then, you'll need to include beaker-puppet as a dependency right
-next to beaker itself.
+For DSL Extension Libraries, you must also ensure that you `require` the
+library in your test files. You can do this manually in individual test files
+or in a test helper (if you have one). You can [use
+`Bundler.require()`](https://bundler.io/v1.16/guides/groups.html) to require
+the library automatically. To explicitly require it:
 
-Once you've done that & installed the gems, in your test, you'll have to
 ```ruby
 require 'beaker-puppet'
 ```
