Now that you have cloned the devstack repository, you need to
configure devstack before deploying it. This is done with a ``local.conf``
file. For manila, the local.conf file can also determine which back end(s)

API features in Manila `that are not supported by some drivers

Using a dummy back end driver
`````````````````````````````
If you're absolutely new to manila code development, you may want to skip a
real storage driver altogether and attempt a development environment that
abstracts the back end storage layer. This could also be the situation if
you're building API integrations such as CLI, UI or SDK clients. Here, you
probably don't care about restrictions that individual back end choices bring
you such as their lack of support for optional API features. Manila ships a
fake backend driver called "Dummy Driver" that supports all API features and
is capable of operating in both DHSS modes. You may use the following `local
.conf` sample to bootstrap your devstack with a "Dummy" driver. Do remember
however that you cannot really *use* the resources that are provisioned by
this driver.
