title: how to create an Extjs app using sencha cmd
body: <p>I am new to sencha. I need to work on ExtJS and would like to create an app using sencha cmd. I have tried many things but not getting a clear info to create an app with sencha cmd. </p>
  
  <p>Please help me by treating as a beginner to build an application.</p>
  
  <p>Also after the installation of sencha cmd how can we start this to run sencha commands? When I try any command in normal terminal it shows me '<code>sencha is not recognized</code>' in windows PC. Also I've given the sencha cmd path in the environment variable PATH.</p>
