+You can set a **custom Schema and component resolver globally** at init time by using the `richText` init option:
+
+```js
+import { richTextSchema, storyblokInit } from "@storyblok/js";
+
+const mySchema = deepClone(richTextSchema) // you can make a copy of the default richTextSchema
+// ... and edit the nodes and marks, or add your own.
+// Check the base richTextSchema source here https://github.com/storyblok/storyblok-js-client/blob/master/source/schema.js
+
+storyblokInit({
+  accessToken: "<your-token>"
+  richText: {
+    schema: mySchema,
+    resolver: (component, blok) => {
+      switch (component) {
+        case "my-custom-component":
+          return `<div class="my-component-class">${blok.text}</div>`;
+          break;
+        default:
+          return "Resolver not defined";
+      }
+    }
+  }
+})
+```
+
+You can also set a **custom Schema and component resolver only once** by passing the options as the second parameter to `renderRichText` function:
+
+```js
+import { renderRichText } from "@storyblok/js";
+
+renderRichText(blok.richTextField, {
+  schema: mySchema,
+  resolver: (component, blok) => {
+    switch (component) {
+      case "my-custom-component":
+        return `<div class="my-component-class">${blok.text}</div>`;
+        break;
+      default:
+        return `Component ${component} not found`;
+    }
+  },
+});
+```
