 ### Deploy the smart contract to the Internet Computer
 
 ```bash
-dfx deploy --network=ic basic_bitcoin --argument '(variant { Testnet })'
+dfx deploy --network=ic basic_bitcoin --argument '(variant { testnet })'
 ```
 
 #### What this does
 - `dfx deploy` tells the command line interface to `deploy` the smart contract
 - `--network=ic` tells the command line to deploy the smart contract to the mainnet ICP blockchain
-- `--argument '(variant { Testnet })'` passes the argument `Testnet` to initialize the smart contract, telling it to connect to the Bitcoin testnet
+- `--argument '(variant { testnet })'` passes the argument `testnet` to initialize the smart contract, telling it to connect to the Bitcoin testnet
