 ## Development
 
+### Test environment
+
+Start MongoDB with this script:
+
+```
+script/testenv
+```
+
 ### Testing
 
 To run the tests for a specific store. You must first set a `BUNDLE_GEMFILE` in
 the environment.
 
+You can also use Docker, see the section below this one.
+
 ```sh
 bundle exec rake
 ```
 
 Examples:
 
 ```sh
-BUNDLE_GEMFILE=gemfiles/rails-4.0-mongo.gemfile bundle exec rake
-BUNDLE_GEMFILE=gemfiles/rails-4.0-mongoid.gemfile bundle exec rake
-BUNDLE_GEMFILE=gemfiles/rails-4.1-mongo.gemfile bundle exec rake

+#### Docker testing
+
+To run tests in a Docker container with a specific Ruby version and gemfile:
+
+```sh
+BUNDLE_GEMFILE=gemfiles/rails-6.0-mongo.gemfile script/test
+```
+
+The `BUNDLE_GEMFILE` environment variable is required. Ruby version defaults to 3.4 but can be customized:
+
+```sh
+RUBY_VERSION=2.7 BUNDLE_GEMFILE=gemfiles/rails-6.0-mongo.gemfile script/test
+```
