I didn't publish it as a single theme folder because a few of the pages are added and modified manually, so you should manually create some extra folders in source for the new pages and modify the _config.yml if you only have the single theme folder.
So i just pushed the whole hexo project for your convenience, all pre settings and boilerplates are included, have a look and go ahead customizing your own blog!
git clone https://github.com/yogesum/nga-blog.git
cd nga-blog
npm install
Modify _config.yml file with your own info.
Especially the section:
deploy:
type: git
repo: https://github.com/yogesum/nga-blog
branch: gh-pages
Replace with your own repo!
hexo new post IMAPOST
hexo serve // run hexo in local environment
hexo clean && hexo deploy // hexo will push the static files automatically into the specific branch(gh-pages) of your repo!
