-# Envoy WebAssembly Filter
-
-In this example, we show how a WebAssembly(WASM) filter can be used with the Envoy
-proxy. The Envoy proxy [configuration](./envoy.yaml) includes a Webassembly filter
-as documented [here](https://www.envoyproxy.io/docs/envoy/latest/).
-<!--TODO(bianpengyuan): change to the url of Wasm filter once the doc is ready.-->
-
-
-
-## Quick Start
-
-1. `docker-compose build`
-2. `docker-compose up`
-3. `curl -v localhost:18000`
-
-Curl output should include our headers:
-
-```
-# <b> curl -v localhost:8000</b>
-* Rebuilt URL to: localhost:18000/
-*   Trying 127.0.0.1...
-* TCP_NODELAY set
-* Connected to localhost (127.0.0.1) port 18000 (#0)
-> GET / HTTP/1.1
-> Host: localhost:18000
-> User-Agent: curl/7.58.0
-> Accept: */*
-> 
-< HTTP/1.1 200 OK
-< content-length: 13
-< content-type: text/plain
-< location: envoy-wasm
-< date: Tue, 09 Jul 2019 00:47:14 GMT
-< server: envoy
-< x-envoy-upstream-service-time: 0
-< newheader: newheadervalue
-< 
-example body
-* Connection #0 to host localhost left intact

-## Build WASM Module
-
-Now you want to make changes to the C++ filter ([envoy_filter_http_wasm_example.cc](envoy_filter_http_wasm_example.cc))
-and build the WASM module ([envoy_filter_http_wasm_example.wasm](envoy_filter_http_wasm_example.wasm)).
-
-1. Build WASM module
-   ```shell
-   bazel build //examples/wasm:envoy_filter_http_wasm_example.wasm
-   ```
-
-## Build the Envoy WASM Image
-
-<!--TODO(incfly): remove this once we upstream WASM to envoyproxy main repo.-->
-
-For Envoy WASM runtime developers, if you want to make changes, please
-
-1. Follow [instructions](https://github.com/envoyproxy/envoy-wasm/blob/master/WASM.md).
-2. Modify `docker-compose.yaml` to mount your own Envoy.
+To learn about this sandbox and for instructions on how to run it please head over
+to the [envoy docs](https://www.envoyproxy.io/docs/envoy/latest/start/sandboxes/wasm-cc).
