 ## VFS examples
 ### MemoryVFS and MemoryAsyncVFS
-These implementations store database pages in memory. The default SQLite VFS already does that, so their value is mainly to provide minimal working examples for writing a VFS. First-time VFS implementers should probably start by looking at these classes, as well as the [SQLite VFS documentation](https://www.sqlite.org/vfs.html).
+These implementations store database pages in memory. The default SQLite VFS already does that, so their value is mainly to provide minimal working examples for writing a VFS or to help debugging investigations by providing a comparative baseline for behavior and/or performance. First-time VFS implementers should probably start by looking at these classes, as well as the [SQLite VFS documentation](https://www.sqlite.org/vfs.html).
 
 ### IDBBatchAtomicVFS
 This VFS stores database pages in IndexedDB. IndexedDB works on all contexts - Window, Worker, SharedWorker, service worker, extension - which makes IDBBatchAtomicVFS a good general purpose VFS.
