Hello @hicorp,
In order to add slider please follow below instructions
1. Create a post, give title and description and set featured image.
2. If you want to add more slides in the slider, create more post (like if you want add three slides in the slider than you have to create three post and set feature image for them).
3. Now go to customizer >> Awada options >> Slider options
4. select all posts that you create for the slider (In the multi select box).
Q. For you second query need to add more seconds??
Ans You need to edit the code in js file
Go Awada >> js >> custom.js
Open custom.js file in any text editor and go to line number 55
on that line you can see below line of code
speed : 1500,
Now you have to add below code next to speed : 1500,
interval : 4000,
and change to interval time and speed according to your need
Save the changes
Thank You
