+# meta-clang (a C language family frontend and LLVM compiler backend)
+
+This layer provides [clang/llvm](http://clang.llvm.org/) as alternative to your system
+C/C++ compiler for OpenEmbedded based distributions along with gcc
+
+# Getting Started
+
+```shell
+git clone git://github.com/openembedded/openembedded-core.git
+cd openembeeded-core
+git clone git://github.com/openembedded/bitbake.git
+git clone git://github.com/kraj/meta-clang.git
+
+$ . ./oe-init-build-env
+```
+
+Edit conf/bblayers.conf to add meta-musl to layer mix e.g.
+
+```python
+BBLAYERS ?= " \
+  /home/kraj/openembedded-core/meta-clang \
+  /home/kraj/openembedded-core/meta \
+  "
+```
+
+# Building
+
+Below we build for qemuarm machine as an example
+
+```shell
+$ MACHINE=qemuarm bitbake core-image-minimal
+```
+# Running
+
+```shell
+$ runqemu qemuarm
+```
+
+# Limitations
+
+Currently core-image-minimal is buildable/bootable for ARM, x86, x86_64
+based qemu machines
+MACHINE variable and TCLIBC variables can also be set in conf/local.conf to avoid typing it on commandline on any bitbake invocation
+
+
+# Dependencies
+
+```

+
+Send pull requests to openembedded-devel@lists.openembedded.org with '[meta-clang]' in the subject'
+
+When sending single patches, please use something like:
+
+'git send-email -M -1 --to openembedded-devel@lists.openembedded.org --subject-prefix=meta-clang][PATCH'
+
+You are encouraged to fork the mirror on [github](https://github.com/kraj/meta-clang/)
+to share your patches, this is preferred for patch sets consisting of more than 
+one patch. Other services like gitorious, repo.or.cz or self hosted setups are 
+of course accepted as well, 'git fetch <remote>' works the same on all of them.
+We recommend github because it is free, easy to use, has been proven to be reliable 
+and has a really good web GUI.
