+### Running with bundler
+
+Running `bundle exec guard` will not run the specs with bundler. You need to change the `cmd` option to `bundle exec rspec`:
+
+``` ruby
+guard :rspec, cmd: 'bundle exec rspec' do
+  # ...
+end
+```
+
 ### List of available options:
 
 ``` ruby
 cmd: 'zeus rspec'      # Specify a custom rspec command to run, default: 'rspec'
 spec_paths: ['spec']   # Specify a custom array of paths that contain spec files
