 portability. Here are some things you should have on your system in order to
 compile the Git repository tree:
 
-  - GNU Autotools (Automake >= 1.10, Autoconf >= 2.50, Autoheader >= 2.50;
+  - [GNU Autotools](http://www.gnu.org/software/autoconf/)
+    (**Automake >= 1.10**, **Autoconf >= 2.50**,
+    **Autoheader >= 2.50**;
     make sure your system-wide `automake` points to a recent version!)
-  - [GNU Libtool](http://www.gnu.org/software/autoconf/) >= 2.2
-  - Perl (optional: needed for `make check` and tests)
+  - **[GNU Libtool](https://www.gnu.org/software/libtool/) >= 2.2**

+### Optional dependencies

+Optional packages to build LTTng-tools man pages:
+
+  - **[AsciiDoc](http://www.methods.co.nz/asciidoc/) >= 8.4.5**
+    (previous versions may work, but were not tested)
+  - **[xmlto](https://fedorahosted.org/xmlto/) >= 0.0.21** (previous
+    versions may work, but were not tested)
+
+Note that the man pages are already built in a distribution tarball.
+In this case, you only need AsciiDoc and xmlto if you indend to modify
+the AsciiDoc man page sources.
