+# Building the Man Pages
+
+The man pages are created with `asciidoc`, `docbook`, and `xmlto`.
+
+## Debian/Ubuntu
+
+This is the easiest since Debian and Ubuntu automatically install the
+dependencies correctly.
+
+```bash
+$ sudo apt-get install -y build-essential asciidoc xmlto
+```
+
+You should then be able to run `make` and the man pages will be
+produced.
+
+## Mac OS X
+
+Mac OS X also has the tools necessary to build the docs, but one of the
+dependencies gets installed incorrectly and you need an environment
+variable to run it correctly.
+
+Use Homebrew to install the dependencies. There might be other methods
+to get the dependencies, but that's left up to the reader if they want
+to use a different package manager.
+
+If you have Homebrew installed, you should already have the Xcode tools
+and that should include `make`.
+
+```bash
+$ brew install asciidoc xmlto
+```
+
+Then set the following environment variable everytime you run `make`.
+
+```bash
+export XML_CATALOG_FILES=/usr/local/etc/xml/catalog
+```
