-Debugging the editor with gdb
------------------------------
-
-If you are writing or correcting bugs affecting Godot Engine's editor,
-remember that the binary will by default run the project manager first,
-and then only run the editor in another process once you've selected a
-project. To launch a project directly, you need to run the editor by
-passing the ``-e`` argument to Godot Engine's binary from within your
-project's folder. Typically:
-
-.. code-block:: none
-
-    $ cd ~/myproject
-    $ gdb godot
-    > run -e
-
-Or:
-
-.. code-block:: none
-
-    $ gdb godot
-    > run -e --path ~/myproject

 Debugging and profiling
 =======================

+Debugging the editor
+--------------------
+
+When working on the Godot editor keep in mind that by default the executable
+will start in the project manager mode. Opening a project from the project
+manager spawns a new process, which stops the debugging session. To avoid that
+you should launch directly into the project using ``-e`` and ``--path`` launch
+options.
+
+For example, using ``gdb`` directly, you may do this:
+
+.. code-block:: none
+
+    $ gdb godot
+    > run -e --path ~/myproject
+
+You can also run the editor directly from your project's folder. In that case,
+only the ``-e`` option is required.
+
+.. code-block:: none
+
+    $ cd ~/myproject
+    $ gdb godot
+    > run -e
+
+You can learn more about these launch options and other command line arguments
+in the :ref:`command line tutorial <doc_command_line_tutorial>`.
+
+If you're using a code editor or an IDE to debug Godot, check out our
+:ref:`configuration guides <doc_configuring_an_ide>`, which cover the setup
+process for building and debugging with your particular editor.
