 This gem provides Capistrano deployment tasks used by Stanford Libraries' Digital Library Systems and Services group.
 
 ## Included Tasks
 
-### Bundle 2-style Configuration
+### Remote Execution
 
-To override the capistrano-bundler gem and use Bundler 2-style configuration without using deprecated arguments, you can set the following settings in `config/deploy.rb`:
+Sometimes you want to execute a command on all boxes in a given environment, and dlss-capistrano's got your back:
 
-```ruby
-set :bundler2_config_use_hook, true # this is how to opt-in to bundler 2-style config. it's false by default
-set :bundler2_config_roles, [:app] # feel free to add roles to this array if you need them
-set :bundler2_config_deployment, true # this is true by default
-set :bundler2_config_without, 'production' # exclude development, and test bundle groups by default
-set :bundler2_config_path, '/tmp' # set to '#{shared_path}/bundle' by default
+```shell
+$ cap qa remote_execute["ps -ef | grep rolling | grep -v grep"]
+00:00 remote_execute
+      ps -ef | grep rolling | grep -v grep
+      ps -ef | grep rolling | grep -v grep

 ### Sidekiq symlink
 
 Every time the version of Sidekiq or Ruby changes, a corresponding Puppet PR must be made in order to update the XSendFilePath that allows Apache to access the bundled Sidekiq gem's assets. dlss-capistrano provides a hook to create a symlink to the bundled Sidekiq to avoid having to do this:
