title: How to use API documentation
body: <p>People generally say they use API documentation and code.</p>
  
  <p>I'm relatively okay in JAVA language,meaning I can write simple programs.
  Recently for the project am working on, I'm asked to work on SOAPUI tool and am reading SOAPUI API for writing code in Groovy. While doing this, I got this question.</p>
  
  <p>How to start using API documentation ( for any language/thing)?
  Lets says, I want to start using Google Map API or Yahoo developer API. </p>
  
  <p>Is there any structured ways of reading and understanding API? Which Classes to use first or how to call or use various methods.</p>
  
  <p>What one should do before reading particular API and how can one became familiar in creating things by reading and understanding API and start building things upon? </p>
  
  <p>What skills one should have to do this? How to develop such skills. </p>
