+# Usage
+
+In your specs.watchr file just add:
+
+    @specs_watchr ||= Rspec::Rails::Watchr.new(self)
+
+Then launch `watchr` as usual (probably `bundle exec watchr`).
+
+## Instructions
+
+The normal behavior is similar to `autotest --fast-start --no-full-after-failed` 
+but gives the user a bit more control over execution. By hitting CTRL+C (or CMD+. on OSX)
+you get the following prompt:
+
+    ^C (Interrupted with CTRL+C)
+    --- What to do now? (q=quit, a=all-specs, r=reload): 
+
+## Advanced
+
+If you want to override some path matching:
+
+    @specs_watchr ||= Rspec::Rails::Watchr.new(self) do |path, specs|
+      case path
+      when %r{lib/calibration_with_coefficients}
+        specs.grep(%r{models/(logarithmic|polynomial)_calibration})
+      when %r{app/models/telemetry_parameter}
+        specs.grep(%r{models/telemetry_parameter})
+      end
+    end
+
