I have created a post for this. There you can get some info and example too in the name of Yug Decor. So, you see the post here I posted is from Dec 2015 and the new post I have provided link is from May of 2017. That much time I took to understand and get some idea. It takes time to learn yourself and get some original idea. I have shared some detail in the example. If you want to buy and learn along then start with that info and buy one SME stock of your choice.
