+### Excluding folders
+
+You can exclude folders from being sent by using the `--exclude` flag with a string of comma-delimited exclusions. For example, if you want to send a folder but exclude any `node_modules` folders or `.venv` folders:
+
+```bash
+croc send --exclude "node_modules,.venv" [folder]

+Exclusions work by excluding any absolute path that contains the string. So in the above example, any folder named `node_modules` or `.venv` will be excluded from the transfer.

 You can pipe to `croc`:
