 ## Usage
 After installing `pandacash-cli`, it can be used as a command-line tool to quickly spin up a local development BCH blockchain with a single command. The local blockchain comes with ten pre-funded BCH addresses, which can be used in the local development process. `pandacash-cli` will also spin up a REST API to interface with the local blockchain that is fully compatible with [BITBOX](https://developer.bitcoin.com/bitbox/).
 
+**Command Line**
 ```bash
-pandacash-cli
+$ pandacash-cli <options>
 ```
 
+Options:
+* `-a` or `--accounts`: Specify the number of accounts to generate at startup.
+* `-m` or `--mnemonic`: bip39 mnemonic phrase for generating a PRNG seed, which is in turn used for hierarchical deterministic (HD) account generation.
+* `--debug`: Show debug output from the bitcoin node.
+
