+## System requirements
+
+We currently only support Linux and FreeBSD. Support for other UNIX-like
+operating systems may be added in the future, but we do not have any plans to
+support Windows.
+
 ## Build dependencies
 
 * Git
 * GNU Make
 * C compiler
 * Recent Go toolchain
+* [libgit2](https://libgit2.org)
+* A recent [mandoc](https://mandoc.bsd.lv)
+  (we recommend using the latest CVS checkout)

+locations.
