-		 * Insert a token before another token in a language literal
-		 * As this needs to recreate the object (we cannot actually insert before keys in object literals),
-		 * we cannot just provide an object, we need an object and a key.
-		 * @param inside The key (or language id) of the parent
-		 * @param before The key to insert before.
-		 * @param insert Object with the key/value pairs to insert

+		 * Inserts tokens _before_ another token in a language definition or any other grammar.
+		 *
+		 * ## Usage
+		 *
+		 * This helper method makes it easy to modify existing languages. For example, the CSS language definition
+		 * not only defines CSS highlighting for CSS documents, but also needs to define highlighting for CSS embedded
+		 * in HTML through `<style>` elements. To do this, it needs to modify `Prism.languages.markup` and add the
+		 * appropriate tokens. However, `Prism.languages.markup` is a regular JavaScript object literal, so if you do
+		 * this:
+		 *
+		 * ```js
+		 * Prism.languages.markup.style = {
+		 *     // token
+		 * };
+		 * ```
+		 *
+		 * then the `style` token will be added (and processed) at the end. `insertBefore` allows you to insert tokens
+		 * before existing tokens. For the CSS example above, you would use it like this:
+		 *
+		 * ```js
+		 * Prism.languages.insertBefore('markup', 'cdata', {
+		 *     'style': {
+		 *         // token
+		 *     }
+		 * });
+		 * ```
+		 *
+		 * ## Special cases
+		 *
+		 * If the grammars of `inside` and `insert` have tokens with the same name, the tokens in `inside`'s grammar
+		 * will be ignored.
+		 *
+		 * This behavior can be used to insert tokens after `before`:
+		 *
+		 * ```js
+		 * Prism.languages.insertBefore('markup', 'comment', {
+		 *     'comment': Prism.languages.markup.comment,
+		 *     // tokens after 'comment'
+		 * });
+		 * ```
+		 *
+		 * ## Limitations
+		 *
+		 * The main problem `insertBefore` has to solve is iteration order. Since ES2015, the iteration order for object
+		 * properties is guaranteed to be the insertion order (except for integer keys) but some browsers behave
+		 * differently when keys are deleted and re-inserted. So `insertBefore` can't be implemented by temporarily
+		 * deleting properties which is necessary to insert at arbitrary positions.
+		 *
+		 * To solve this problem, `insertBefore` doesn't actually insert the given tokens into the target object.
+		 * Instead, it will create a new object and replace all references to the target object with the new one. This
+		 * can be done without temporarily deleting properties, so the iteration order is well-defined.
+		 *
+		 * However, only references that can be reached from `Prism.languages` or `insert` will be replaced. I.e. if
+		 * you hold the target object in a variable, then the value of the variable will not change.
+		 *
+		 * ```js
+		 * var oldMarkup = Prism.languages.markup;
+		 * var newMarkup = Prism.languages.insertBefore('markup', 'comment', { ... });
+		 *
+		 * assert(oldMarkup !== Prism.languages.markup);
+		 * assert(newMarkup === Prism.languages.markup);
+		 * ```
+		 *
+		 * @param {string} inside The property of `root` (e.g. a language id in `Prism.languages`) that contains the
+		 * object to be modified.
+		 * @param {string} before The key to insert before.
+		 * @param {Grammar} insert An object containing the key-value pairs to be inserted.
+		 * @param {Object<string, any>} [root] The object containing `inside`, i.e. the object that contains the
