+
+Babel syntactic sugar for replacing `this` with `getCurrentInstance()` in Vue JSX with @vue/composition-api
+
+### Babel Compatibility Notes
+
+- This repo is only compatible with Babel 7.x
+
+### Usage
+
+Install the dependencies:
+
+```sh
+# for yarn:
+yarn add @vue/babel-sugar-composition-api-render-instance
+# for npm:
+npm install @vue/babel-sugar-composition-api-render-instance --save
+```
+
+In your `.babelrc`:
+
+```json
+{
+  "plugins": ["@vue/babel-sugar-composition-api-render-instance"]
+}
+```
+
+However it is recommended to use the [configurable preset](../babel-preset-jsx/README.md) instead.
+
+### Details
+
+This plugin automatically replaces `this` in `setup()` with `getCurrentInstance()`. This is required for JSX to work in @vue/composition-api as `this` is not available in `setup()`
+
+Input:
+
+```jsx
+defineComponent({ 
+  setup() {
+    return () => <MyComponent vModel={a.b} />
+  }
+})
+```
+
+Output (without @vue/babel-sugar-composition-api-render-instance):
+
+```jsx
+defineComponent({
+  setup() {
+    return () => <MyComponent model={{
+      value: a.b,
+      callback: $$v => {
+        this.$set(a, "b", $$v);
+      }
+    }} />
+  }
+})
+```
+
+Output (with @vue/babel-sugar-composition-api-render-instance):
+
+```jsx
+import { getCurrentInstance } from "@vue/composition-api";
+
+defineComponent({
+  setup() {
+    const __currentInstance = getCurrentInstance();
+
+    return () => <MyComponent model={{
+      value: a.b,
+      callback: $$v => {
+        __currentInstance.$set(a, "b", $$v);
+      }
+    }} />
+  }
+})
+```
