+   Welcome to wxWidgets for iOS
+   ----------------------------
+
+wxiOS is far from a full supported port, but can be used
+as base for simple applications and future improvements.
+
+It requires Xcode with iOS SDK 9.0 or later. Xcode is available
+for free in the OS X app store.
+
+More info about the wxWidgets project (including all the
+other ports and version of wxWidgets) can be found at the
+main wxWidgets homepage at:
+
+    https://www.wxwidgets.org/
+
+To build wxiOS you should use Xcode to open the minimal samples
+Xcode project file located at:
+
+    samples/minimal/minimal_iphone.xcodeproj
+
+That project files includes wxiphone.xcodeproj so you just need
+to hit run in order to see the minimal sample running in the
+simulator.
+
+The library can also be build via configure/make:
+
+    mkdir build_ios
+    cd build_ios
+    ../configure --with-osx_iphone --enable-monolithic \
+        --with-macosx-version-min=8.0 --disable-shared \
+        --with-macosx-sdk=$(xcrun --sdk iphonesimulator --show-sdk-path)
+    make
+
+
+Please send problems concerning installation, feature requests,
+bug reports or comments to the wxWidgets users list. These can
+be found at https://www.wxwidgets.org/support/mailing-lists/
