npm start doesn't always work the first time

[johnathanDOS]

The first time you do npm start to build a local version of the docs site, you may get an error that looks like this:

> node ./scripts/server.js

module.js:549
    throw err;
    ^

Error: Cannot find module 'metalsmith-redirect'

npm ERR! Failed at the particle-docs@0.3.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

To workaround the issue:

1. Delete the node_modules directory
2. Redo npm install
3. Retry npm start

The site should build and you should see it at localhost:8080
