RE: https://developer.salesforce.com/trailhead/lightning_components/lightning_components_creating

First, the "Creating Components" module seems like it is incorrect / out of date, as it does not mention anything about a lightning page, which is required before you can build a tab. The "create a tab" section doesn't say anything about creating a page first - I had to figure that out by myself.

Next, I have created a tab, and put my new page in the tab, and the tab does appear in Salesforce1. However, I need to include my component on the page, but my new custom component (configured in this same module) does not appear in the list of available custom components in the app builder.

Is there a more accurate training module for this topic?
