Hello!

Jekyll is awesome, setting blog on Jekyll is quick and easy.

gem install jekyll
jekyll new myblog && cd $_
jekyll serve

Modify _config.yml for basic details as blog name, your social profiles and description.

Now goto _posts and look welcome posts and modify it.

On removing category or changing them you would get 404 if you refresh current page because modifying category changes the url. So goto home and open the post.
