+## Installation
+- The usual ``make && make install`` is supported, along with `DESTDIR`
+
+Also depending on your security policy, you might want `suc(1)`,
+which was made opt-in due to it ignoring the target's shell entry
+when arguments are given.
+
+To still compile & install it: ``make suc && make suc-install``
+
## Unsupported
- Broken authentication systems like PAM and [nsswitch](https://skarnet.org/software/nsss/nsswitch.html)
- Remote host arguments (believed to be legacy)
