+Debugging your AGL application is based on the GNU Project Debugger
+([GDB](https://www.gnu.org/software/gdb/)).
+In order to use GDB, you must use `xds-gdb` as a wrapper on GDB to
 cross-debug your application.
+For information on `xds-gdb`, see the
+"[Client Part](./client-part.html)" topic.
 
-This tool allows you to debug an application built with XDS without the need to install gdb or any cross tools.

-Two debugging models are supported:
+XDS supports two debugging models:
 
-1. native debugging
-1. XDS remote debugging requiring an XDS agent/server setup and that allows you to cross debug your application.
+* Native debugging
 
-By default XDS debug model is used and you need to define `XDS_NATIVE_GDB`
-variable to use native gdb debug mode instead.
+* XDS remote debugging
 
----
+The default debugging model is XDS remote.
+To use this model, you must have previously set up the XDS
+agent and server so that you can cross-debug your application.
+See
+"[Overview](./xds-overview.html)" section along with "Installing XDS"
+for more information on getting set up.
 
-Links to subchapters :
+If you want to use the native debugging model, you must define the
+`XDS_NATIVE_GDB` environment variable.
