+When providing bug reports or including issues the output of the both
+the master-customize.log mentioned above and the result of the
+devel-tools/juju-inspect-local-provider script.

Parse error. Perhaps "When reporting bugs or issues, please include both the master-customize.log (described above) and the output of the devel-tools/juju-inspect-local-provider script."?

Otherwise LGTM

+Troubleshooting
+===============
+
+Local development is still a young and evolving feature and because of
+the many complex system interactions its possible you'll encounter
+some speed bumps along your path. There are a number of log files you
+should be aware of when trying to understand how the system behaves.
+
+Once``juju bootstrap`` has run you'll have a directory in place on
+your filesystem at the location specified in your
+environments.yaml. In here you'll find a number of files related to
+the runtime of the local deployment system. The first step is to
+verify that the machine-agent.log includes a line similar to::
+
+    2011-10-05 14:43:56,327: juju.agents.machine@INFO: Machine agent started id:0 deploy:<class 'juju.machine.unit.UnitContainerDeployment'> provider:'local'
+
+When you first attempt to deploy a unit the time consuming process of
+creating a unit will begin. The first time you run this it can taGke
+quite some time and if your impatient and need to check on the process
+`lxc-ls` will show you which templates are created or being created
+and::
+
+    pgrep lxc| head -1| xargs watch pstree -alU
+
+will give you a refeshing view of the first container as its built.
+
+Once a container is built you should have access to it via ssh through
+the `juju ssh` as normal.
+
+If services are not running properly as exposed by `juju status` the
+log file in *data-dir/units/master-customize.log* should provide insight
+into the nature of the error.
+
+When providing bug reports or including issues the output of the both
+the master-customize.log mentioned above and the result of the
+devel-tools/juju-inspect-local-provider script. If you are not running
+a development checkout this script should be located at
+*/usr/lib/juju/juju/misc/devel-tools/juju-inspect-local-provider*
+
+By passing the name of the container as an argument to that script
+additional information abou the container will be included in the
+output as well. To find the name of the container in question `lxc-ls`
+can be used.
