Guide: jsreport-cli with pug template engine instalation

Create a local folder that will hold the server, i.e. (~/myTools/jsreport)
Go to that directory (cd ~/myTools/jsreport)
Do yarn global add jsreport-cli (you can also use npm install -g jsreport-cli)
Execute jsreport init (this will create folder structure)
Add this template engine or anyother (i.e. ejs) this command: yarn add jsreport-pug
Start the server with this command jsreport start

When jsreport starts, it looks for engines in node_modules folder and if it founds any it loads them with no extra configuration.
