In the Alexa app, this is achieved by selecting the main menu button (found in the upper left-hand corner of the screen) and choosing the Skills option. From here you can browse Alexa skills by category or other criteria such as those favored the most by its large user base. You can also search for skills by keyword or name through this same interface.
The flash briefing skill submission process provides the steps to submit descriptive information about your skill and configure one or more feeds for each skill. You can then test your skill in your Alexa-enabled device and provide additional information about how you handle customer data and privacy. Once you've provided this information, you can submit your flash briefing skill for certification and use by customers.
