+## How to use the CLI
+
+`db-cli` is a command line interface for the database. It reads the database and output all the accounts in a JSON format.
+
+**Usage:**
+```bash
+Usage: db-cli -d <db> [-v <verbosity>] [-e <evm-output>] [-s <substrate-output>]
+
+Webb Faucet Database CLI
+
+Options:
+  -d, --db          sled database path
+  -v, --verbosity   control verbosity level
+  -e, --evm-output  output file for evm addresses
+  -s, --substrate-output
+                    output file for substrate addresses
+  --help            display usage information
+```
+
+## Examples
+
+1. Output all the accounts in the database to stderr
+```bash
+./db-cli -d ./faucet
+```
+2. Output all the accounts in the database to json files
+
+```bash
+./db-cli -d ./faucet -v 2 -e evm.json -s substrate.json
+```
