The Renderer : renderer
-The renderer defines the HTML output of a given token. If you supply a `renderer` object to the Marked options, it will be merged with the built-in renderer and any functions inside will override the default handling of that token type.
+The renderer defines the HTML output of a given token. If you supply a `renderer` in the options object passed to `marked.use()`, any functions in the object will override the default handling of that token type.
Calling `marked.use()` to override the same function multiple times will give priority to the version that was assigned *last*. Overriding functions can return `false` to fall back to the previous override in the sequence, or resume default behavior if all overrides return `false`. Returning any other value (including nothing) will prevent fallback behavior.
