Installation Workflow represents tasks that should be executed on action's install. Using Installation Workflow allows gathering user input and preparing data only once to be reused each time when action is launched. For example, a Call Action would include the following tasks in Installation Workflow:

1. Prompt the user to choose a contact and save it.
   
2. Prompt the user to compose the action icon based on the contact's photo.
   
3. Prompt the user to choose a phone number and save it.

As result of Installation of such Action:

• Action gets human readable title e.g. "Call Kate".
  
• Action gets clearly readable icon that shows properly arranged and scaled contact photo.
  
• Phone number is known, so when the user launches the action - app just initiates a phone call without a need of any additional user input.
  

It is possible to re-launch Installation Tasks for an action by turning ON the Edit mode, taping the Share button and choosing the "Reset" action. This allows to basically reset the action and initialize it with fresh set of data. For example, re-initializing the "Call Kate" action would allow choosing different contact e.g. John Doe, which effectively turns the action to be "Call John".
