+=head1 THIS SUCKS
+
+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>:
+
+ my $s = My::Schema->connect(...);
+ my $dh = DBIx::Class::DeploymentHandler->({ schema => $s });
+
+ $dh->prepare_version_storage_install;
+ $dh->install_version_storage;
+
+Then set your database version:
+
+ $dh->add_database_version({ version => $s->version });
+
+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 it's 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.
+
+=head1 DONATIONS
+
+If you'd like to thank me for the work I've done on this module, don't give me
+a donation. I spend a lot of free time creating free software, but I do it
+because I love it.
-vim: ts=2 sw=2 expandtab
+Instead, consider donating to someone who might actually need it. Obviously
+you should do research when donating to a charity, so don't just take my word
+on this. I like Children's Survival Fund:
+L<http://www.childrenssurvivalfund.org>, but there are a host of other
+charities that can do much more good than I will with your money.
