+## CLI Tool
+
+The CLI tool supports generating proofs for transactions and receipts. Use the following commands based on your requirements:
+
+**Generate a Proof via CLI**
+To generate a proof for a transaction, use the following command:
+
+`cargo run --bin eth-trie-proofs tx <TRANSACTION_HASH> [RPC_URL]`
+
+To generate a receipt proof:
+
+`cargo run --bin eth-trie-proofs receipt <TRANSACTION_HASH> [RPC_URL]`
+
+As a default, `https://ethereum-rpc.publicnode.com` is used as an RPC provider. This will probably work for recent transactions, but it is advised to use a dedicated RPC.
