title: What to do if a typings (or tsd) is not available?
body: <p>I was looking over the TypeScript handbook and I can't seem to find the answer.</p>
  
  <p>If I am using a library that no typings exist, what are my options?</p>
  
  <p>One is to create the typings file, but this I don't really want to do.</p>
  
  <p>What are my other options, I seem to remember some kind of 'declare' keyword ?</p>
  
  <p>Or maybe something in the tsconfig ?</p>
  
  <p>I assume there is a way of declaring this variable (type) globally so every time I use it, it would just work.</p>
  
  <p>And I presume there is a way of just declaring it only available in one file.</p>
  
  <p>Of course the best way would be to include a typings file but this won't always be available.</p>
