-### Build WebView shell
-
-[Android WebView](https://developer.android.com/reference/android/webkit/WebView.html)
-is a system framework component. Since Android KitKat, it is implemented using
-Chromium code (based off the [content module](https://dev.chromium.org/developers/content-module)).
-It is possible to test modifications to WebView using a simple test shell. The
-WebView shell is a view with a URL bar at the top (see [code](https://code.google.com/p/chromium/codesearch#chromium/src/android_webview/test/shell/src/org/chromium/android_webview/test/AwTestContainerView.java))
-and is **independent** of the WebView **implementation in the Android system** (
-the WebView shell is essentially a standalone unbundled app).
-As drawback, the shell runs in non-production rendering mode only.
-
-```shell
-ninja -C out/Release android_webview_apk
-build/android/adb_install_apk.py out/Release/apks/AndroidWebView.apk
-```
-
-If, instead, you want to build the complete Android WebView framework component and test the effect of your chromium changes in other Android app using the WebView, you should follow the [Android AOSP + chromium WebView instructions](https://www.chromium.org/developers/how-tos/build-instructions-android-webview)

just drop anything that mentions the test shell

Let me know if this is an improvement.
