+## Building and installation discouragements
+
+There are a few steps you have to carefully consider before building and installing
+opendoas:
+
+* There are less eyes on random doas ports, just because sudo had a vulnerability
+  does not mean random doas ports are more secure if they are not reviewed
+  or pam is configured incorrectly.
+* If you want to use pam; You have to [configure pam](#pam-configuration)
+  and failing to do so correctly might leave a big open door.
+* Use the configure script to configure the opendoas.
+* Use the default make target to build the software.
+* If you really want to install a setuid binary that depends on
+  pam being correctly configured, use the make install target
+  to install the software.
