-# Adding a new IDL file
-
-Ladybird's build system does a lot of work of turning the IDL from a Web spec into code, but there are a few things you'll need to do yourself.
-
-For the sake of example, let's say you're wanting to add the `HTMLDetailsElement`.
-
-1. Create `LibWeb/HTML/HTMLDetailsElement.idl` with the contents of the IDL section of the spec. In this case, that would be:
-```webidl
-[Exposed=Window]
-interface HTMLDetailsElement : HTMLElement {
-    [HTMLConstructor] constructor();
-
-    [CEReactions] attribute boolean open;
-};
-```
-
-2. If the IDL refers to other IDL types, you need to import those. For example, `CSSRule` has an attribute that returns a `CSSStyleSheet`, so that needs to be imported:
-```webidl
-#import <CSS/CSSStyleSheet.idl>
-
-interface CSSRule {
-    readonly attribute CSSStyleSheet? parentStyleSheet;
-};
-```
-
-3. Add a `libweb_js_bindings(HTML/HTMLDetailsElement)` call to [`LibWeb/idl_files.cmake`](../Libraries/LibWeb/idl_files.cmake) (only for top-level interfaces)
-
-4. Forward declare the generated class in [`LibWeb/Forward.h`](../Libraries/LibWeb/Forward.h):
-    - `HTMLDetailsElement` in its namespace.
-
-5. If your type isn't an Event or Element, you will need to add it to [`is_platform_object()`](../Meta/Lagom/Tools/CodeGenerators/LibWeb/BindingsGenerator/IDLGenerators.cpp)
-   so that it can be accepted as an IDL parameter, attribute or return type.
