 This library uses the wonderful [stack_strings](https://github.com/termermc/nim-stack-strings) library for secrets.
 Meaning secrets are fixed length one can use `--otp.secretSize:50` to override the size.
 By default the secret length is 32 bytes.
+Due to this the best way to handle secrets is as follows:
+```nim
+let mySecret = "S3cret"
+if mySecret.len < secretSize:
+  let hotp = Hotp.init(mySecret)
+  assert hotp.at(0) == 755224
+else:
+  # Do something errory here
+  raise (ref ValueError)(msg: "Secret size too large")
+```
