+### Logging
+
+By default, the logging is set to `info`. You can change the logging level by passing the argument `--log-level` with the desired level.
+The available levels are `error`, `warn`, `info`, `debug`, and `trace`. Also, the logs have JSON format. If you wish to run the code with
+human-readable logs, you can pipe the output of the program to `pino-pretty`. See the example below for more information on how to do this.
+
+You can configure the log level of some of the modules of the price pusher as well. The available modules are PriceServiceConnection, which
+is responsible for connecting to the Hermes price service, and Controller, which is responsible for checking the prices from the Hermes
+and the on-chain Pyth contract and deciding whether to push a new price. You can configure the log level of these modules by passing the
+`--price-service-connection-log-level` and `--controller-log-level` arguments, respectively.
+
 ### Example
 
 For example, to push `BTC/USD` and `BNB/USD` prices on Fantom testnet, run the following command:
 
 ```sh
-npm run dev -- evm \
+pnpm run dev evm \
   --endpoint https://endpoints.omniatech.io/v1/fantom/testnet/public \
   --pyth-contract-address 0x5744Cbf430D99456a0A8771208b674F27f8EF0Fb \
   --price-service-endpoint https://hermes.pyth.network \
   --mnemonic-file "./mnemonic" \
-  --price-config-file "./price-config.stable.sample.yaml"
+  --price-config-file "./price-config.stable.sample.yaml" \
+  | pnpm exec pino-pretty # Make logs human-readable

 You can also provide a config file instead of providing command line options, run the following command:
 
 ```sh
-npm run start -- injective --config "./config.injective.sample.json"
+pnpm run start injective --config "./config.injective.sample.json"
