+### Using `croc` on Linux or Mac OS
+
+On Linux and Mac OS, the sending & receiving is slightly different to avoid [leaking the secret via the process name](https://nvd.nist.gov/vuln/detail/CVE-2023-43621). On these systems you will need to run `croc` with the secret as an environment variable. For example, to receive with the secret `***`:
+
+```
+CROC_SECRET=*** croc
+```
+
+This will show only `croc` in the process list of a multi-user system and not leak the secret.
+
+For a single-user system the default behavior can be permanently enabled by running
+
+```
+croc --classic

+Run this command again to disable classic mode.
