Shapley Mac highSierra; want gallery and slider plugin
I hope you are well today and thank you for your question.
The home page won’t won’t work with a slider, based on the teme was designed.
You’d need custom development to implement slider and gallery on the home page.
If you are not a developer then you can consider customizations offered by Envato,
In regards to sliders and galleries, you can use plugins with shortcode features to display sliders and galleries in other pages and posts.
All plugins aren’t made equal, simply search the plugin repository and pick one that meets your needs.
Preferably one with a high rating.
