-# create-wasm-app
-> an npm init project for generating a project that consumes rust-generated wasm via webpack
+# DUP Tools front
+
+Based on the [create-wasm-app] template to provide a full js interface using `dup-tools-wasm`, a toolbox for developers wishing to use the DUP procotole.
+
+Currently, only the document validator feature is implemented, but the `dup-tools-wasm` library already allows you to do potentially much more !
+
+[create-wasm-app]: https://github.com/rustwasm/create-wasm-app.git 
 
 ## Usage
 
+For local use, you only need `npm` :
+
 ```
-npm init wasm-app
+npm install
+npm start
 ```
 
-## What's Included
-
-- `.gitignore`: ignores `node_modules`
-- `LICENSE-APACHE` and `LICENSE-MIT`: most Rust projects are licensed this way, so these are included for you
-- `README.md`: the file you are reading now!
-- `index.html`: a bare bones html document that includes the webpack bundle
-- `index.js`: example js file with a comment showing how to import and use a wasm pkg
-- `package.json` and `package-lock.json`: 
-  - pulls in devDependencies for using webpack:
-      - [`webpack`](https://www.npmjs.com/package/webpack)
-      - [`webpack-cli`](https://www.npmjs.com/package/webpack-cli)
-      - [`webpack-dev-server`](https://www.npmjs.com/package/webpack-dev-server)
