+## Tips and Tricks
+
+   * Use "debug builds" only when needed. Debugging builds are helpful for
+     development, but they can slow down performance. Use
+     `-DCMAKE_BUILD_TYPE=Release` when debugging isn't necessary.
+   * Enable Selective Daemons when testing specific components. Don't start
+     unnecessary daemons.
+   * Preserve Existing Data skip cluster reinitialization between tests by
+     using the `-n` flag.
