 Run bitcoind on regtest:
    ```
-   bitcoind -regtest -rpcport=8332
+   bitcoind -regtest
    ```
 
 Create a new wallet, if needed:
    ```
-   bitcoin-cli -regtest -rpcport=8332 createwallet test
+   bitcoin-cli -regtest createwallet test
    ```
 
 Load wallet (this command may take a while if you have lot of UTXOs):
    ```
-   bitcoin-cli -regtest -rpcport=8332 loadwallet test
+   bitcoin-cli -regtest loadwallet test
    ```
 
 Get a new address:
    ```
-   address=$(./src/bitcoin-cli -regtest -rpcport=8332 getnewaddress)
+   address=$(bitcoin-cli -regtest getnewaddress)
    ```
 
 Mine blocks to the previously generated address. You need at least 101 blocks before you can spend. This will take some time to execute (~1 min):
    ```
-   bitcoin-cli -regtest -rpcport=8332 generatetoaddress 101 $address
+   bitcoin-cli -regtest generatetoaddress 101 $address
    ```
 
 Send 0.1 BTC at 5 sat/vB to another address:
    ```
-   ./src/bitcoin-cli -named -regtest -rpcport=8332 sendtoaddress address=$(./src/bitcoin-cli -regtest -rpcport=8332 getnewaddress) amount=0.1 fee_rate=5
+   bitcoin-cli -named -regtest sendtoaddress address=$(bitcoin-cli -regtest getnewaddress) amount=0.1 fee_rate=5
    ```
 
 See more example of `sendtoaddress`:
    ```
-   ./src/bitcoin-cli sendtoaddress # will print the help
+   bitcoin-cli sendtoaddress # will print the help
    ```
 
-Mini script to generate transactions with random TX fee-rate (between 1 to 100 sat/vB). It's slow so don't expect to use this to test mempool spam, except if you let it run for a long time, or maybe with multiple regtest nodes connected to each other.

    done
    ```
 
 Generate block at regular interval (every 10 seconds in this example):
    ```
-   watch -n 10 "./src/bitcoin-cli -regtest -rpcport=8332 generatetoaddress 1 $address"
+   watch -n 10 "bitcoin-cli -regtest generatetoaddress 1 $address"
    ```
