+Meta layer for Boot to Qt Software Stack
+========================================
+
+Boot to Qt (b2qt) is the reference distro used in Qt for Device Creation [1].
+It combines Poky, Qt and various BSP meta layers to provide an integrated
+solution for building device images and toolchains with the latest Qt version.
+
+Currently used dependencies, meta repositories and their revisions are shown in
+scripts/manifest.xml
+

+Setting up build environment
+----------------------------
+
+Use the Google repo tool to initialize the Yocto environment:
+
+  cd <BuildDir>
+  repo init -u git://code.qt.io/yocto/boot2qt-manifest -m <manifest>
+  repo sync
+
+Where manifest is one of the XML manifest files available in the
+https://code.qt.io/cgit/yocto/boot2qt-manifest.git/tree/ repository.
+A separate manifest file is available for each release and all the
+development branches have manifests that follow the latest changes.
+
+If you have already cloned the meta-boot2qt repository, you can alternatively
+use the `b2qt-init-build-env` script to initialize the build environment:
+
+  ./b2qt-init-build-env init --device <name>
+
