Missing documentation

[sbuckpesch]

Great boilerplate. Got me starting fast on a bigger project. Unfortunately the docs are not very detailed. A lot of things I needed to research or did not get it yet.

1. Environment variables
How do you manage environment variables? In the webpack config you included .env in the plugin section. As well you include the serverless-kms-secrets plugin. How do you manage that?

2. Workflow
A description of a typical workflow would be helpful. Here is mine.

1. Create a new project using a template / Ref: https://github.com/nordcloud/serverless-boilerplate
   sls install -u https://github.com/nordcloud/serverless-boilerplate -n myservicename
2. Create a new function incl. a test and two HTTP endpoints / Ref: https://github.com/nordcloud/serverless-mocha-plugin
   sls create function -f myFunction --handler functions/myFunction/index.handler --httpEvent "post myResource" --httpEvent "get myResource"
3. Display the logs in a new console / Ref: https://serverless.com/framework/docs/providers/aws/guide/workflow#streaming-logs
   sls logs -f myFunctionName --startTime 10m -t
4. Invoke a function locally in Debug-Mode using Webpacks watch functionality / Refs: https://serverless.com/framework/docs/providers/aws/cli-reference/invoke#invoke-local https://github.com/serverless-heaven/serverless-webpack#run-a-function-locally-on-source-changes
   SLS_DEBUG=true sls invoke local -f functionName -p functions/calculateMatch/match.json --watch
5. Deploy
   sls deploy --stage dev
