The samples in this folder used to be under src/_includes/code. Despite that, the sources were not being included anywhere. It is likely that the sources appear in some pages none-the-less. What needs to be done is the following:

• Each app/sample needs to be fully reviewed (and potentially simplified).
• If the sources are in fact being used in site pages, then they need to be integrated as proper code excerpts. See Code excerpts for details.
• Each app/sample should be tested, at least with a smoke test.
