+## Warnings
+
+Please be sure to read the following warnings and considerations before running this code on your local workstation, shared systems, or production environments.
+
+### Database configuration
+
+The sample application code and templates in this repository contain database connection settings and credentials that rely on being able to use sqlite.
+
+### Automatic test execution
+
+The sample application code and templates in this repository contain scripts that automatically execute tests via the postCommit hook.  These tests assume that they are being executed against a local test sqlite database. If alternate database credentials are supplied to the build, the tests could make undesireable changes to that database.
