 ## Requirements
 
-- Rust toolchain & Cargo
+- [Rust toolchain & Cargo](https://doc.rust-lang.org/cargo/getting-started/installation.html) installed
+- A wallet with some funds to send transactions
 
 ## How to use
 
-1. Prepare the environment variables (either in a `.env` file, or as CLI arguments):
+Bolt Client offers different ways to send commitment requests. Here's how to use them:
 
-   - `BOLT_RPC_URL` or `--rpc-url`: the URL of the Bolt RPC server (default: Chainbound's RPC)
-   - `BOLT_PRIVATE_KEY` or `--private-key`: the private key of the account to send transactions from
-   - `BOLT_NONCE_OFFSET` or `--nonce-offset`: the offset to add to the account's nonce (default: 0)
-   - `--blob`: bool flag to send a blob-carrying transaction (default: false)
+### Use the default Bolt RPC
 
-**Optionally**, you can use the following flags to fetch the lookahead data from the beacon chain directly
-instead of relying on the RPC server:
+For regular usage, you can use the default Bolt RPC server to automatically fetch the
+lookahead data from the beacon chain and send the transaction to the next Bolt sidecar in line.
+
+To do this, prepare the environment variables (either in a `.env` file, or as CLI arguments):
+
+- `BOLT_PRIVATE_KEY` or `--private-key`: the private key of the account to send transactions from
+- `--blob`: bool flag to send a blob-carrying transaction (default: false)
+- `--count`: the number of transactions to send in a single request (default: 1)
+
+Run the CLI tool:
+
+```shell
+ cargo run
+```
+
+### Use your own beacon node and registry contract
+
+If you don't want to use the default RPC server, you can send transactions manually.
+To do this, you need to provide the following environment variables (either in a `.env` file, or as CLI arguments):
 
 - `--use-registry`: bool flag to fetch data from a local node instead of the RPC_URL (default: false)
+- `BOLT_RPC_URL` or `--rpc-url`: the URL of an execution client (e.g. Geth)'s RPC server (default: Chainbound's RPC)
+- `BOLT_NONCE_OFFSET` or `--nonce-offset`: the offset to add to the account's nonce (default: 0)
 - `BOLT_REGISTRY_ADDRESS` or `--registry-address`: the address of the bolt-registry smart contract
-- `BOLT_BEACON_CLIENT_URL` or `--beacon-client-url`: the URL of the CL node to use
+- `BOLT_BEACON_CLIENT_URL` or `--beacon-client-url`: the URL of the beacon client's HTTP server
