-# Kunkun Template UI Extension
+# Kunkun String Utils Extension
 
-This is a template for a template UI extension. (UI follows pre-defined template)
+This is an extension for [Kunkun](https://docs.kunkun.sh/) that provides a set of string utility functions.
 
-[./src/index.ts](./src/index.ts) is the default entrypoint for the extension. You can import any other files in this file, but the build process will bundle them into a single file.
+Currently supported functions:
 
-## Pros and Cons
-
-This type of extension is suitable for simple use cases, such as a list or form. All components are pre-defined, so there is not much room for customization. If you want more flexibility on the UI, consider using [Custom UI Extension](https://docs.kunkun.sh/extensions/custom-ui-ext/), which requires some frontend knowledge but gives you full control over the UI.
-
-Read documentation at https://docs.kunkun.sh/extensions/worker-template/
-
-Make sure you understand what this type of extension is capable of.
-
-### Pros
-
-- Simple to develop, no need for any frontend knowledge.
-- Small bundle size (~40KB)
-  - [Custom UI Extension](https://docs.kunkun.sh/extensions/custom-ui-ext/) are usually larger than 300KB.
-
-### Cons
-
-- Limited UI customization. Not suitable for complex use cases.
-
-Consider [Custom UI Extension](https://docs.kunkun.sh/extensions/custom-ui-ext/) if you need more complex UI.
