+Engine Compilation Configuration Editor
+=======================================
+
+The "Engine Compilation Configuration Editor" in Godot is a tool that allows developers 
+to configure and customize the compilation settings for the Godot game engine 
+while exporting your project as executable.
+This includes options for enabling or disabling specific features, text rendering 
+options, and nodes and classes.
+
+By using this editor, developers can tailor the engine's compilation to suit their
+specific project requirements, optimize for size, and manage the inclusion or 
+exclusion of various engine features.
+
+Usage
+=====
+
+To access the tool, navigate to `Project > Tools > Engine Compilation Configuration Editor...`.
+You will see the following window:
+
+.. image:: img/engine_compilation_config_editor.webp
+
+Under "Configure Engine Compilation Profile", you will see a comprehensive set of 
+options that you can enable or disable, grouped under "General Features", "Text 
+Rendering and Font Options", and "Nodes and Classes".
+By default, all features, font rendering options 
+(except the :ref:`Text Fallback Server <class_TextServerFallback>`),
+and classes will be active.
+You can click on the items to read their descriptions below.
+
+The settings affect the final size of the exported project; therefore, you may consider 
+disabling the items that you will not need in your project.
+For example, if you develop only 2D games and will never use a 3D-related node in your 
+project, you may consider disabling `3D Engine` and `3D Physics` from the 
+`General Feature` section.
+
+In this window, you can create profiles to load later for different projects.
+Type a name under `Profile` and save it. This will create a new `.build` file.
+
+If you want to revert your changes back to the original values, you can use 
+"Reset to Defaults."
+
+You can also use the "Detect From Project" button if you want to quickly select only 
+the nodes and classes that your project is using, and disable others automatically.
+
+If you still want to have some nodes and resources selected even though you do not 
+use them, you can force their selection by typing them under "Forced Classes on Detect."
+Separate multiple node and class names by a comma (,). For example, writing 
+``Bone2D, Line2D`` and pressing on "Detect from Project" will keep these two nodes 
+selected even if the Godot does not detect them in the project's files.
