-# Vue 3 + Typescript + Vite
+# React Flow in Vue3 = Revue Flow
 
-This template should help get you started developing with Vue 3 and Typescript in Vite.
+This repo is still a big construction site with nothing really finished.
+Please check out [React Flow](https://reactflow.dev/) if you like the idea.
 
-## Recommended IDE Setup
+### Motivation
+Seeing as many libraries exist in the React ecosystem and Vue sadly does not get the same
+love and attention, I decided to port the React Flow library to Vue.js.
 
-[VSCode](https://code.visualstudio.com/) + [Vetur](https://marketplace.visualstudio.com/items?itemName=octref.vetur). Make sure to enable `vetur.experimental.templateInterpolationService` in settings!
+## Setup
+This project uses Vite.
 
-### If Using `<script setup>`
+```bash
+# start (dev)
+$ yarn dev
 
-[`<script setup>`](https://github.com/vuejs/rfcs/pull/227) is a feature that is currently in RFC stage. To get proper IDE support for the syntax, use [Volar](https://marketplace.visualstudio.com/items?itemName=johnsoncodehk.volar) instead of Vetur (and disable Vetur).
+# build app
+$ yarn build
 
-## Type Support For `.vue` Imports in TS
-
-Since TypeScript cannot handle type information for `.vue` imports, they are shimmed to be a generic Vue component type by default. In most cases this is fine if you don't really care about component prop types outside of templates. However, if you wish to get actual prop types in `.vue` imports (for example to get props validation when using manual `h(...)` calls), you can use the following:
-
-### If Using Volar
-
-Run `Volar: Switch TS Plugin on/off` from VSCode command palette.
-
-### If Using Vetur
-
-1. Install and add `@vuedx/typescript-plugin-vue` to the [plugins section](https://www.typescriptlang.org/tsconfig#plugins) in `tsconfig.json`
-2. Delete `src/shims-vue.d.ts` as it is no longer needed to provide module info to Typescript
-3. Open `src/main.ts` in VSCode
-4. Open the VSCode command palette
-5. Search and run "Select TypeScript version" -> "Use workspace version"
+# serve app from dist
+$ yarn serve
+```
