I’ve heard about Jekyll CMS. And I liked an idea blogging like a hacker. I thought it’s very convenient to write and very simple and fast to read. It was exactly what I need. Fast and light site for simple blogging of my notes with little code snippets. Also, it’s really easy to install. You just need clone repository with a suitable theme and edit the config. Now you can just make a new file in the _posts directory, push it in your github.io repository and feel the magic:) 

git clone git://github.com/hemangsk/DevJournal #repository of this theme
cd DevJournal
vim _config.yml
vim _posts/1st-post.md
vim CNAME #if you want to customize your domain, you should also add CNAME record in your DNS
git push ssh://git@github.com/%username%/%username%.guthub.io


And now everything else will make GitHub.
Check out the Jekyll docs for more info on how to get the most out of Jekyll. File all bugs/feature requests at Jekyll’s GitHub repo. If you have any questions, you can ask them on Jekyll Talk.
