 ## Getting Started
 
-To begin you will need `nodejs` and `firebase-tools`
+This documentation describes features of the `firebase-framework` but generally does not cover firebase options in general. For example, to find out how you can specify a specific version of nodejs see the firebase docs here: https://firebase.google.com/docs/functions/manage-functions#set_nodejs_version
 
-nodejs v8.15.x is recommended because cloud functions by default uses node 8. \
-While it is not the most recent LTS build it can be downloaded here:
-<https://nodejs.org/download/release/v8.15.1/>

 \* Though billing is required, you can expect the overall cost to be manageable, as each Cloud Scheduler job costs \$0.10 (USD) per month, and there is an allowance of three free jobs per Google account (as of the time of writing). \* The keepAlive feature adds a route to the service at '/heartbeat'. This will not conflict with wildcard routes in the service but would conflict with a route named the same.
