+    \page qtwebassembly-platform-notes.html
+    \title Qt WebAssembly Platform Notes
+
+    \brief Contains information about issues that are specific to the Qt WebAssembly module.
+
+    \section1 Supported target browsers and devices
+
+    \section2 Desktop
+
+    \list
+        \li Chrome
+        \li FireFox
+        \li Safari
+        \li Edge(Chrome)
+    \endlist
+
+    If the browser supports WebAssembly, then Qt should run.
+
+    \note Qt has a fixed WebGL requirement, also for apps that do not
+    use WebGL directly. Browsers often blacklist WebGL for older/unsupported
+    GPUs.
+
+    \section2 Mobile
+
+    \list
+        \li Android Browser
+        \li Mobile Safari
+    \endlist
+
+    \note There is currently no support for text input using the virtual
+    keyboard. Safari currently does not support wasm modules of the size
+    Qt produces.
+
+    Qt does not make direct use of operating system features and it makes
+    no difference if, for example, FireFox runs on Windows or macOS. Qt
+    does use some operating system adaptations, for example for ctrl/cmd
+    key handling on macOS.
+
+    \section2 Supported Qt Modules
+
+    Qt for WebAssembly supports a subset of the Qt modules. The list below
+    lists the currently tested modules. The list can be pasted as arguments
+    to \c make.
+
+    \badcode
+        module-qtbase module-qtdeclarative module-qtquickcontrols2 module-qtwebsockets module-qtsvg module-qtcharts module-qtmqtt
+    \endcode
+
+    Other modules are untested and may work.  Are not supported: QtMultimedia
+    and QtWebView
+
+    \section3 Known issues
+
+    Refer to the section "Known issues" in the wiki : \l{https://wiki.qt.io/Qt_for_WebAssembly#Known issues}{Known issues}.
+
+    \section3 General notes
+
+    \list
+    \li Debugging: Qt debug and logging output is printed on the JavaScript
+        console, which can be accessed via browser "Developer Tools" or similar.
+    \li Nested event loops are not supported. Applications should not call, for
+        example, QDialog::exec() or create a new QEventLoop object.
+    \li Qt renders application content to a canvas element, and does not use
+        (other) native DOM elements. This means accessibility (screen readers)
+        are not supported and that text inputs won't trigger virtual keyboards.
+    \li WebGL is required, even for applications which do not use OpenGL themselves.
+        Most modern browsers support WebGL, but note that some browsers blacklist
+        certain older GPUs. The Qt loader will detect this and display an error message.
+    \li Child OpenGL windows are not supported. The window compositor (in the Qt
+        for Wasm platform plugin) supports raster windows only.
+    \li Qt will detect OpenGL support as OpenGL ES. In reality the browser will
+        be providing WebGL. WebGL is based on ES and is very similar, but there
+        are some incompatibilities. See WebGL and OpenGL Differences.
+    \li Applications do not have access to system fonts. Font files must be
+        distributed with the application, for example in Qt resources. Qt for
+        WebAssembly itself embeds one such font.
+    \li High-DPI and scaling: High-DPI rendering is supported, and so is setting
+        the overall UI visual size using the browser zoom feature. Browser font
+        size (and type) settings have no effect on Qt applications.
+    \li There may be artifacts of uninitialized graphics memory on some Qt Quick
+        Controls 2 components, such as checkboxes.
+    \li Network access: the web sandbox limits network access to a subset of what
+        is available for native apps.
+        \list
+        \li QNetworkAccessManager http requests to the web page origin server, or
+            to a server which supports CORS.
+        \li QWebScoket connections to any host.
+        \li TCP and UDP socked tunneling using over WebSockets using a websockify
+            server [implemented by Emscripten, not tested].
+            \list
+            \li Websockify v0.8.0 can be used to tunnel TCP connections with QT5.12
+                but it is MANDATORY to specify the base64 or binary subprotocols before
+                calling QWebSocket::open().
+            \li For example:
+
+                QWebSocket socket;
+
+                QUrl url{QString("ws://server:port")};
+
+                QNetworkRequest request{url};
+
+                request.setRawHeader("Sec-WebSocket-Protocol", "binary");
+
+                socket.open(request);
+            \endlist
+        \endlist
+
+    \li Link-time warnings of the form: "cannot represent a NaN literal '0x7fdae4bde910'
+        with custom bit pattern", are expected.
+    \li Expected footprint (download size): Wasm modules as produced by the compiler can
+        be large, but compress well.
+
+        \table
+        \header
+            \li Example
+            \li gzip
+            \li brotli
+        \row
+            \li helloglwindow (QtCore + QtGui)
+            \li 2.8M
+            \li 2.1M
+        \row
+            \li wiggly widget (QtCore + QtGui + QtWidgets)
+            \li 4.3M
+            \li 3.2M
+        \row
+            \li SensorTag (QtCore + QtGui + QtWidgets + QtQuick + QtCharts)
+            \li 8.6M
+            \li 6.3M
+        \endtable
+
+        Compression is typically handled on the web server side, using standard compression
+        features: the server compresses automatically or picks up pre-compressed versions of
+        the files. There's generally no need to have special handling of wasm files.
+    \endlist

+A couple of comments:
+
+1. We should have a point about installing the 1.38.27 Emscripten SDK like in the wiki. Unfortunately there are sometimes changes in the SDK that breaks Qt, so we need to make sure everyone is on the same version as us.
+
+2. It has instructions for "build Qt from sources". Starting with Qt 5.13.0, we will have binary packages, so this will be the main way people use it. We could have a section about how to build as an optional step but mention that it is optional. Also, it currently says "5.12", but this should probably not specify version number.
+
+3. Two additional things it would be useful to have there: The instructions on how to test-run an application (/path/to/emscripten/emrun --browser=firefox appname.html) and Supported Qt Modules.
