 =head1 NAME
 
-Gitalist - Catalyst based application
+Gitalist - A modern git web viewer
 
 =head1 SYNOPSIS
 
-    script/gitalist_server.pl
+    perl script/gitalist_server.pl --repo_dir /home/me/code/git
+
+=head1 INSTALL
+
+As Gitalist follows the usual Perl module format the usual approach
+for installation should work, e.g.:
+
+    perl Makefile.PL
+    make
+    make test
+    make install
+
+or
+
+    cpan -i Gitalist
+
+You can also L<check Gitalist out from its git repository|/"GETTING GITALIST">
+and run it, in this case you'll additionally need the author modules,
+but no configuration will be needed as it will default to looking
+for repositories the directory above the checkout.
 
 =head1 DESCRIPTION
 
-[enter your description here]
+Gitalist is a web frontend for git repositories based on
+L<gitweb.cgi|https://git.wiki.kernel.org/index.php/Gitweb> and backed by
+L<Catalyst>.
+
+=head2 History
+
+This project started off as an attempt to port I<gitweb.cgi> to a
+Catalyst app in a piecemeal fashion. As it turns out, thanks largely
+to Florian Ragwitz's earlier effort, it was easier to use I<gitweb.cgi>
+as a template for building a new Catalyst application.
+
+=head1 GETTING GITALIST
+
+You can install Gitalist from CPAN in the usual way:
+
+    cpan -i Gitalist
+
+Alternatively, you can get Gitalist using git.
+
+The canonical repository for the master branch is:
+
+    git://git.shadowcat.co.uk/catagits/Gitalist.git
+
+Gitalist is also mirrored to GitHub at L<https://github.com/broquaint/Gitalist>,
+and a number of people have active forks
+with branches and/or new features in the master branch.
+
+=head1 BOOTSTRAPPING
+
+As of C<0.002001> Gitalist can now be bootstrapped to run out of its
+own directory by installing its prerequisites locally with the help of
+L<local::lib>. So instead of installing the prerequisites to the
+system path with CPAN they are installed under the Gitalist directory.
+
+To do this clone Gitalist from the L<Shadowcat repository mentioned
+above|/"GETTING GITALIST"> or grab a snapshot from broquaint's GitHub repository:
+
+    https://github.com/broquaint/Gitalist/downloads
+
+With the source acquired and unpacked run the following from within the
+Gitalist directory:
+
+    perl script/bootstrap.pl
+
+This will install the necessary modules for the build process which in
+turn installs the prerequisites locally.
+
+B<NB:> The relevant bootstrap scripts aren't available in the CPAN dist
+as the bootstrap scripts should not be installed.
+
+=head1 INITIAL CONFIGURATION
+
+Gitalist is configured using L<Catalyst::Plugin::Configloader>. The supplied sample
+configuration is in L<Config::General> format, however it is possible to configure
+Gitalist using other config file formats (such as YAML) if you prefer.
+
+=head2 WHEN CHECKING GITALIST OUT OF GIT
+
+Gitalist from git includes a minimal C<gitalist_local.conf>, which sets the repository
+directory to one directory higher than the Gitalist repository.
+
+This means that if you check Gitalist out next to your other git checkouts, then starting
+the demo server needs no parameters at all:
+
+    Gitalist [master]$ perl script/gitalist_server.pl
+    You can connect to your server at http://localhost:3000
+
+=head2 FOR CPAN INSTALLS
+
+Gitalist can be supplied with a config file by setting the C<< GITALIST_CONFIG >>
+environment variable to point to a configuration file.
+
+If you install Gitalist from CPAN, a default configuration is installed along with gitalist,
+which is complete except for a repository directory. You can get a copy of this configuration
+by running:
+
+  cp `perl -Ilib -MGitalist -e'print Gitalist->path_to("gitalist.conf")'` gitalist.conf
+
+You can then edit this configuration, adding a C<repo_dir> path and customising
+other settings as desired.
+
+You can then start the Gitalist demo server by setting C<< GITALIST_CONFIG >>. For example:
+
+    GITALIST_CONFIG=/usr/local/etc/gitalist.conf gitalist_server.pl
+
+Alternatively, if you only want to set a repository directory and are otherwise happy with
+the default configuration, then you can set the C<< GITALIST_REPO_DIR >> environment
+variable, or pass the C<< --repo_dir >> flag to any of the scripts.
+
+    GITALIST_REPO_DIR=/home/myuser/code/git gitalist_server.pl
+    gitalist_server.pl --repo_dir home/myuser/code/git
+
+The C<< GITALIST_REPO_DIR >> environment variable will override the repository directory set
+in configuration, and will itself be overridden by he C<< --repo_dir >> flag.
+
+=head1 RUNNING
+
+Once you have followed the instructions above to install and configure Gitalist, you may want
+to run it in a more production facing environment than using the single threaded developement
+server.
+
+The recommended deployment method for Gitalist is FastCGI, although Gitalist can also be run
+under L<mod_perl|https://perl.apache.org/> or as pure Perl with L<Catalyst::Engine::PreFork>.
+
+Assuming that you have installed Gitalist's dependencies into a L<local::lib>, and you
+are running from a git checkout, adding a trivial FCGI script as C<script/gitalist.fcgi>
+(this file is specifically in C<.gitignore> so you can have your own copy):
+
+    #!/bin/sh
+    exec /home/t0m/public_html/Gitalist/script/gitalist_fastcgi.pl
+
+This example can be seen live here:
+
+    http://example.gitalist.com
+
+=head2 Plack
+
+If you would like to run Gitalist under L<Plack> then one need only
+make use of L<plackup|search.cpan.org/perldoc?plackup> and the
+C<.psgi> found under C<scripts/>:
+
+    plackup script/gitalist_app.psgi
+
+=head1 CONFIGURATION
+
+The Gitalist config is loaded with L<Catalyst::Plugin::ConfigLoader>
+and the available config options are:
+
+=over
+
+=item no_gravatars
+
+If true don't display gravatars. May be desirable if you are worried about
+leaking repo names via the browser referer headers.
+
+=back
+
+=head2 Model::CollectionOfRepos
+
+=over
+
+=item repo_dir
+
+A directory containing the directories to show.
+
+=item repos
+
+A list of directories containing repositories to show.
+
+=item search_recursively
+
+A boolean indicating whether to always search recursively for
+repositories within C<repo_dir>.
+
+=item whitelist
+
+Path a file containing a list of repositories that can be shown. Each
+line in the file will represent the name of a repo to show e.g
+
+  Gitalist
+  some-bare-repo.git
+
+This is compatible with C<gitweb>'s C<projects.list>.
+
+=item export_ok
+
+If provided every must contain a file of the same name to be
+visible. This is similar to C<gitweb>'s functionality.
+
+=item class
+
+If you want a different way of surfacing repositories you can use your
+own model (i.e something that composes
+L<Gitalist::Git::CollectionOfRepositories>) and specify the class name with
+this config option.
+
+=item args
+
+Any additional arguments to be passed into the Model constructor, only
+of use when used in conjunction with C<class> (see above).
+
+=back
+
+=head2 paging
+
+=over
+
+=item log
+
+The number of commits to show in the summary, shortlog and longlog views.
+
+=back
+
+=head2 FASTCGI
+
+Running Gitalist in FastCGI mode requires a webserver with FastCGI
+support (such as apache with L<mod_fcgi|http://www.fastcgi.com/drupal/node/3>
+or L<mod_fcgid|https://httpd.apache.org/mod_fcgid/>). Below is a sample
+configuration using Apache2 with mod_fcgid in a dynamic configuration
+(as opposed to static or standalone mode). More information on these modes and
+their configuration can be found at L<Catalyst::Engine::FastCGI/"Standalone server mode">.
+
+In Apache's F<mime.conf>, add C<AddHandler fcgid-script .fcgi>
+(or C<AddHandler fastcgi-script .fcgi> for mod_fcgi).
+
+And a quick VirtualHost configuration:
+
+    <VirtualHost *:80>
+        ServerName gitalist.yourdomain.com
+        DocumentRoot /path/to/gitalist.fcgi
+        <Directory "/path/to/gitalist.fcgi">
+            AllowOverride all
+            Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
+            Order allow,deny
+            Allow from all
+        </Directory>
+
+        # Tell Apache this is a FastCGI application
+        <Files gitalist.fcgi>
+            #change the below to fastcgi-script if using mod_fcgi
+            SetHandler fcgid-script
+        </Files>
+    </VirtualHost>
+
+Now to access your Gitalist instance, you'll go to
+C<gitalist.yourdomain.com/gitalist.fcgi/> (B<do not forget that trailing> C</>).
+If you'd like a different URL, of course, you'll likely want to use
+L<mod_rewrite|https://httpd.apache.org/docs/mod/mod_rewrite.html> or equivalent.
+
+If you find the need to do some troubleshooting, you can call
+C<http://url_to_gitalist.fcgi?dump_info=1> and/or add export C<GITALIST_DEBUG=1>
+to the top of your F<gitalist.fcgi> file (just below the shebang line).
+
+=head2 Apache config
+
+Apache will refuse C<%2F> in Gitalist URLs unless configured otherwise. Make
+sure C<AllowEncodedSlashes On> is in your F<httpd.conf> file in order for
+this to run smoothly.
+
+To have the static content served statically by Apache, instead of
+Gitalist, then add something like following line to your F<httpd.conf>:
+
+    Alias /static  /usr/local/share/perl/5.10.1/Gitalist/root/static
+
+=head1 CONTRIBUTING
+
+Patches are welcome, please feel free to fork on github and send pull requests, send patches
+from git format-patch to the bug tracker, or host your own copy of gitalist somewhere and
+ask us to pull from it.
+
+=head1 SUPPORT
+
+Gitalist has an active irc community in C<#gitalist> on irc.perl.org, please feel free to stop
+by and ask questions, report bugs or installation issues or generally for a chat about where
+we plan to go with the project.
