+# Testing `sunspot_rails`
+
+Note: All the paths mentioned in here are relative to the current directory, or `sunspot/sunspot_rails`.
+
+The `sunspot_rails` gem is tested with RSpec, and its spec suite is located in `spec`.
+
+These specs are to be run against up to date Rails 2 and Rails 3 applications, included at `spec/rails2` and `spec/rails3`, respectively. The `spec_helper.rb` file loads the environment for these applications based on the `RAILS_ROOT` provided when invoking tests, outlined below.
+
+## Install dependencies
+
+Each application uses Bundler to manage its dependencies. The `Gemfile` also installs the `sunspot` and `sunspot_rails` gems from your copies checked out locally. Because Bundler expands the full path to `sunspot` and `sunspot_rails`, we're excluding its generated `Gemfile.lock` file from version control.
