+## How to use xxDK in your Web Application
+
+To install with npm, run the following:
+
+```
+npm i --save xxdk-wasm
+```
+
+By default, xxdk uses a CDN hosted by the [xx
+foundation](http://xxfoundation.org). If you would like to self-host
+the wasm binaries, you can include the following postinstall script in
+your package.json file:
+
+```
+{
+  ...
+  "scripts": {
+    ...
+    "postinstall": "mkdir -p public && cp -r node_modules/xxdk-wasm public/xxdk-wasm"
+  },
+  ...
+}
+```
+
+You may also run this command manually after installation to
+accomplish the same result.
+
+Then you will need to override the base path with `setXXDKBasePath`
+inside your useEffect statement to load the wasm file from your local
+public assets:
+
+```
+    xxdk.setXXDKBasePath(window!.location.href + "xxdk-wasm");
+```
+
+See the
+[xxdk-examples](https://git.xx.network/xx_network/xxdk-examples) repository for
+examples in react and plain html/javascript.
