+## grovedbg
+
+There is a work in progress implementation of a debugger layer for GroveDB. To use this library with
+these capabilities enabled one needs to set a dependency with `grovedbg` feature. Then, to launch
+visualizer tool to observe the database structure inside of your browser on a port, let's say 10000,
+the following snippet should do:
+
+```rust
+    let db = Arc::new(GroveDb::open("db").unwrap());
+    db.start_visualzier(10000);
+```
+
+Just remember to use Arc because the HTTP server might outlast the GroveDB instance.
