-# rln-db-inspector
-
-This document describes how to run and use the `rln-db-inspector` tool. 
-It is meant to be used to debug and fetch the metadata stored in the RLN tree db.
-
-## Pre-requisites
-
-1. An existing RLN tree db
-
-## Usage
-
-1. First, we compile the binary
-    
-    ```bash
-    make -j16 wakunode2
-    ```
-    This command will fetch the rln static library and link it automatically.
-
-
-2. Define the arguments you wish to use
-
-    ```bash
-    export RLN_TREE_DB_PATH="xxx"
-    ```
-
-3. Run the db inspector 
-
-    ```bash
-    ./build/wakunode2 inspectRlnDb \
-    --rln-relay-tree-path:$RLN_TREE_DB_PATH 
-    ```
-
-    What this does is - 
-    a. loads the tree db from the path provided
-    b. Logs out the metadata, including, number of leaves set, past 5 merkle roots, last synced block number
-
