+### How to run bysquare in the terminal
+
+To encode data from example.json and print it as a string in the terminal, use the following command:
+
+```bash
+npx bysquare --encode example.json
+```
+
+Make sure that path to example.json is correct and contains the data you want to encode.
+
+If you want to display the encoded data as a QR code in the terminal, you can pipe the output of the encode command to qrcode-terminal:
+```bash
+npx bysquare --encode example.json | npx qrcode-terminal
+```
