Jssor slider is very easy to bring into BSS, but word of warning... I have been emailing the developer for about 5 months about a bug I found in the last release with no response, so I have a fear that the project is no longer being actively developed. It still works fine, but I don't think there will be any new versions (nor will the bug get fixed, which is frustrating.)
Anyway, how you bring Jsorr sliders into BSS depends on how you are using the program. Are you building slideshows using their online page (ie. do you have an online jssor account?) or did you download the slider from their github respository?
Unzip the file and you will see an img folder and js folder. They get uploaded to your website's root folder. You can put them in your BSS website's export folder, or just upload them directly with your ftp program.
Then open the HTML file that jssor created and copy everything between...
<!-- #region Jssor Slider Begin -->
<!-- #endregion Jssor Slider End -->
and paste this into a BSS Custom Code component. I usually do something like Container > Row > Custom Code
Export and upload your website BSS, and your jssor slider should work.
