+C<DBIx::Class::DeploymentHandler> is, as its name suggests, a tool for
deploying and upgrading databases with L<DBIx::Class>. It is designed to be
much more flexible than L<DBIx::Class::Schema::Versioned>, hence the use of
L<Moose> and lots of roles.
C<DBIx::Class::DeploymentHandler> itself is just a recommended set of roles
-that we think will not only work well for everyone, but will also yeild the

+that we think will not only work well for everyone, but will also yield the
+best overall mileage. Each role it uses has its own nuances and
documentation, so I won't describe all of them here, but here are a few of the
major benefits over how L<DBIx::Class::Schema::Versioned> worked (and
L<DBIx::Class::DeploymentHandler::Deprecated> tries to maintain compatibility
You started your project and weren't using C<DBIx::Class::DeploymentHandler>?
Lucky for you I had you in mind when I wrote this doc.
-First off, you'll want to just install the C<version_storage>:
+First,
+L<define the version|DBIx::Class::DeploymentHandler::Intro/Sample_database>
+in your main schema file (maybe using C<$VERSION>).
+
+Then you'll want to just install the version_storage:
my $s = My::Schema->connect(...);
- my $dh = DBIx::Class::DeploymentHandler->({ schema => $s });
+ my $dh = DBIx::Class::DeploymentHandler->new({ schema => $s });
$dh->prepare_version_storage_install;
$dh->install_version_storage;
Now you should be able to use C<DBIx::Class::DeploymentHandler> like normal!
+=head1 LOGGING
+
+This is a complex tool, and because of that sometimes you'll want to see
+what exactly is happening. The best way to do that is to use the built in
+logging functionality. It the standard six log levels; C<fatal>, C<error>,
+C<warn>, C<info>, C<debug>, and C<trace>. Most of those are pretty self
+explanatory. Generally a safe level to see what all is going on is debug,
+which will give you everything except for the exact SQL being run.
+
+To enable the various logging levels all you need to do is set an environment
+variables: C<DBICDH_FATAL>, C<DBICDH_ERROR>, C<DBICDH_WARN>, C<DBICDH_INFO>,
+C<DBICDH_DEBUG>, and C<DBICDH_TRACE>. Each level can be set on its own,
+but the default is the first three on and the last three off, and the levels
+cascade, so if you turn on trace the rest will turn on automatically.
