+## Keeping create-yorkie-app in sync with examples
+
+When adding a new example, you have to update create-yorkie-app's [frameworks.ts](../tools//create-yorkie-app/frameworks.ts).
+
+Add FrameworkVariant to the variants array under appropriate category like:
+
+```js
+export const FRAMEWORKS: Array<Framework> = [
+  {
+    name: 'vanilla',
+    display: 'Vanilla',
+    color: yellow,
+    variants: [
+      {
+        name: 'vanilla-codemirror6',
+        display: 'codemirror',
+      },
+      {
+        name: 'vanilla-quill',
+        display: 'quill',
+      },
+      {
+        name: 'profile-stack',
+        display: 'profile-stack',
+      },
+      // Your yorkie example in Vanilla JS
+      {
+        name: 'directory-name',
+        display: 'display-name',
+      },
+    ],
+  },
+  // ...
+];
+```

+## Adding a New Example
+
+Add information about your new example in [frameworks.ts](https://github.com/yorkie-team/yorkie-js-sdk/blob/main/tools/create-yorkie-app/frameworks.ts).
+
+Choose or create an appropriate category (e.g. vanilla, react, nextjs, vue, ...) and add an object like below to variants array.
+
+```ts
+{
+  name: directory_name,
+  display: displayed_name_in_prompt

+```
+
+## Publishing a New Version
+
+Update the version in [package.json](https://github.com/yorkie-team/yorkie-js-sdk/blob/main/tools/create-yorkie-app/package.json#L3).
+
+Publication will be done via [create-yorkie-app-publish.yml](https://github.com/yorkie-team/yorkie-js-sdk/blob/main/.github/workflows/create-yorkie-app-publish.yml) when changes are pushed into main branch.

+# create-yorkie-app
+
+## Usage
+
+You can scaffold yorkie-js-sdk examples by:
+
+```bash
+$ npx create-yorkie-app
+```
+
+The examples have own local dependencies. So you should install dependencies before running examples.
+
+```bash
+# In the directory of the example.
+$ npm install
+```
+
+Then you can run the examples.
+
+```bash
+# In the directory of the example.
+$ npm run dev
+```
+
+Open the browser and go to the URL that is printed in the terminal.
+
+## Note
+
+Yorkie API key or local server is necessary to run each example.
+You can create and manage your projects and API keys at [Yorkie Dashboard](https://yorkie.dev/dashboard). If you want to configure your own server, refer to [this README](../../examples/README.md).
