 ## Advanced usage
 
-By default we produce HTML or Markdown compatible with Telegram, you may want to serialise differently. This module exposes a way to do this: `serialiseWith`. To use this, you must first implement a serialiser with the following type:
+`toHTML` and `toMarkdown` produce HTML or Markdown compatible with Telegram because it's a sensible default for a Telegram library. You may want to serialise differently, to target a different system. This module exposes a way to do this: `serialiseWith`.
+
+To use this, you must first implement a serialiser with the following type:
 
 ```TS
-/**
- * @param match will always be a string
- * @param entity will be undefined for plain text; otherwise the entity
- * @param escape whether or not to escape the inner text
- * @note Serialiser will be called recursively for nested entities, so we don't want to double-serialise
- */
-function myHTMLSerialiser (match: string, entity?: MessageEntity, escape = true): string {
+import type { Serialiser } from "@telegraf/entity";
+
+const myHTMLSerialiser: Serialiser (match, node) {
 	// implement
 }
 ```
 
-Refer to the implementation of the [builtin serialisers](https://github.com/telegraf/entity/blob/master/serialisers.ts) for something you can simply copy-paste and edit until you're satisfied.
+Each matched node will be passed to your function, and you only need to wrap it however you want.

 The builtin escapers are also exported for your convenience:
 
 ```TS
-import { escapers } from "@telegraf/entity";
+import { escapers, type Escaper } from "@telegraf/entity";
 
 escapers.HTML(text); // HTML escaped text
 escapers.MarkdownV2(text); // escaped for Telegram's MarkdownV2
+
+// or
+const yourEscaper: Escaper = match => { /* implement */ };
+```
+
+By using both of these tools, you can implement your own HTML serialiser like so:
+
+```TS
+import { serialiseWith, escapers } from "@telegraf/entity";
+
+const serialise = serialiseWith(myHTMLSerialiser, escapers.HTML);
+serialise(ctx.message);
 ```
