Adding and Using Skills:

To add a skill through the Alexa device, simply say “Alexa, enable [skill name],” and Alexa issues voice-prompt instructions, if needed, to complete the process.

It might be easier to add skills using the Alexa App, as that way you can see a list of them and add the ones that look appealing. To add them through the app, open the Alexa App and select the More tab. Choose Skills & Games, and from there you can see all the skills that can be added. You can use the categories to search for certain skills that you may like. Once you find one you like, choose it and tap on Launch. If you have multiple devices, it will ask you which one you want it on. Just select the device and launch the skill to use it.
