Hello,
You will need to Edit the Files manually using Sublime Text and then upload them to your Web Servers using FTP. You can check out more instructions in the Documentation > Start > Niche Demos Section.
If you are using a Niche Demo, they run on the native style.css and css/js Files and can be found in the Package/HTML Folder with the names: demo-*.html Template.
These are the following Folders/Files you will need for the Resume Niche Template:
css/ Folder
images/ Folder (However, you can delete the Images inside this Folder according to your Preference, but don’t delete the images/icons/ Folder)
include/ Folder (However, you can delete the rs-plugin/ Folder)
js/ Folder
demos/resume Folder
style.css File
index-resume.html File
You can simply delete the other files depending on what you want to use.
This will definitely work fine. Hope this Helps!
