+This README file contains information on the contents of the
+alexa-led layer.
+
+Please see the corresponding sections below for details.
+
+
+Dependencies
+============
+
+This layer depends on:
+
+ URI: git://git.openembedded.org/bitbake
+ branch: master
+
+ URI: git://git.openembedded.org/openembedded-core
+ layers: meta
+ branch: master
+
+ URI: git://git.yoctoproject.org/xxxx
+ layers: xxxx
+ branch: master

+
+Patches
+=======
+
+Please submit any patches against the alexa-led layer to the
+xxxx mailing list (x...@zzzz.org) and cc: the maintainer:

+I. Adding the alexa-led layer to your build
+=================================================
+
+--- replace with specific instructions for the alexa-led layer ---
+
+In order to use this layer, you need to make the build system aware of
+it.
+
+Assuming the alexa-led layer exists at the top-level of your
+yocto build tree, you can add it to the build system by adding the
+location of the alexa-led layer to bblayers.conf, along with any
+other layers needed. e.g.:
+
+ BBLAYERS ?= " \
+ /path/to/yocto/meta \
+ /path/to/yocto/meta-poky \
+ /path/to/yocto/meta-yocto-bsp \
+ /path/to/yocto/meta-alexa-led \
+ "
+
+
+II. Misc
+========
+
+--- replace with specific information about the alexa-led layer ---
