message: Add note about how to properly put Prague registry in npmrc file
diff: @@ -12,6 +12,11 @@ To get started simply
  * Choose "npm"
  * Select the @Release view (this will give versions of the library that work with the production servies)
  * And then follow the steps provided. This involves adding a new line to your project's .npmrc as well as storing credentials to access the private repo on your machine.
  +* IMPORTANT NOTE: VSTS will give you a line like this to put into your .npmrc file:
  + `registry=https://offnet.pkgs.visualstudio.com/_packaging/prague@Release/npm/registry/`
  +
  + You need to prefix that line with @prague in order to not force all package lookups to go to the Prague registry. The line you add to your .npmrc file should actually look like this:
  + `@prague:registry=https://offnet.pkgs.visualstudio.com/_packaging/prague@Release/npm/registry/`
  The [sequence, flowview, and threejs](./api/examples) examples are all setup using the above approach.
