I'm a beginner in using bower and had searched all over the internet for installing the bower but couldn't find step by step method for installing the bower. If you please help me for this I shall be very thankful to everyone.
First you need to install node.js which you can do here: https://nodejs.org/en/download/.
Once you have node installed you need to open a command prompt window. To install bower you enter the command npm install -g bower
