=head1 NAME
Dancer2 - Lightweight yet powerful web application framework
=head1 VERSION
version 1.1.2
=head1 DESCRIPTION
Dancer2 is the new generation of L<Dancer>, the lightweight web-framework for
Perl. Dancer2 is a complete rewrite based on L<Moo>.
Dancer2 can optionally use XS modules for speed, but at its core remains
fatpackable (packable by L<App::FatPacker>) so you could easily deploy Dancer2
applications on hosts that do not support custom CPAN modules.
Dancer2 is easy and fun:
use Dancer2;
get '/' => sub { "Hello World" };
dance;
This is the main module for the Dancer2 distribution. It contains logic for
creating a new Dancer2 application.
=head2 Documentation Index
Documentation on Dancer2 is split into several sections. Below is a
complete outline on where to go for help.
=over 4
=item * Dancer2 Tutorial
If you are new to the Dancer approach, you should start by reading
our L<Dancer2::Tutorial>.
=item * Dancer2 Manual
L<Dancer2::Manual> is the reference for Dancer2. Here you will find
information on the concepts of Dancer2 application development and
a comprehensive reference to the Dancer2 domain specific
language.
=item * Dancer2 Keywords
The keywords for Dancer2 can be found under L<DSL Keywords|Dancer2::Manual/DSL KEYWORDS>.
=item * Dancer2 Deployment
For configuration examples of different deployment solutions involving
Dancer2 and Plack, refer to L<Dancer2::Manual::Deployment>.
=item * Dancer2 Cookbook
Specific examples of code for real-life problems and some 'tricks' for
applications in Dancer can be found in L<Dancer2::Cookbook>
=item * Dancer2 Config
For configuration file details refer to L<Dancer2::Config>. It is a
complete list of all configuration options.
=item * Dancer2 Plugins
Refer to L<Dancer2::Plugins> for a partial list of available Dancer2
plugins. Note that although we try to keep this list up to date we
expect plugin authors to tell us about new modules.
For information on how to author a plugin, see L<Dancer2::Plugin/Writing the plugin>.
=item * Dancer2 Migration guide
L<Dancer2::Manual::Migration> provides the most up-to-date instruction on
how to convert a Dancer (1) based application to Dancer2.

=head3 Other Documentation
=over
=item * Core and Community Policy, and Standards of Conduct
The L<Dancer core and community policy, and standards of conduct|Dancer2::Policy> defines
what constitutes acceptable behavior in our community, what behavior is considered
abusive and unacceptable, and what steps will be taken to remediate inappropriate
and abusive behavior. By participating in any public forum for Dancer or its
community, you are agreeing to the terms of this policy.
=item * GitHub Wiki
Our L<GitHub wiki|https://github.com/PerlDancer/Dancer2/wiki> has community-contributed
documentation, as well as other information that doesn't quite fit within
this manual.
=item * Contributing
how to set up your development environment to contribute to the development of Dancer2,
Dancer2's Git workflow, submission guidelines, and various coding standards.
=item * Deprecation Policy
The L<deprecation policy|Dancer2::DeprecationPolicy> defines the process for removing old,
broken, unused, or outdated code from the Dancer2 codebase. This policy is critical
for guiding and shaping future development of Dancer2.
=back
=head1 SECURITY REPORTS
If you need to report a security vulnerability in Dancer2, send all pertinent
information to L<dancer-security@dancer.pm|mailto:dancer-security@dancer.pm>. These matters are taken
extremely seriously, and will be addressed in the earliest timeframe possible.
