+=head1 NAME
+
+PLP::CGI - CGI interface for PLP
+
+=head1 SYNOPSIS
+
+For most servers you'll need a script executable.
+Example F</foo/bar/plp.cgi>:
+
+    #!/usr/bin/perl
+    use PLP::CGI;
+
+Or install the C<plp.cgi> included with PLP.
+
+=head2 Lighttpd
+
+Usually in F</etc/lighttpd/lighttpd.conf>:
+enable I<mod_cgi> (add/outcomment in server.modules), and add:
+
+    cgi.assign = (
+        ".plp" => "/foo/bar/plp.cgi",
+    )
+
+=head2 Apache
+
+Enable I<mod_actions> and setup F<httpd.conf>
+(often just create a F</etc/apache2/conf.d/plp>) with:
+
+    <IfModule mod_actions.c>
+        ScriptAlias /PLP_COMMON/ /foo/bar/
+        <Directory /foo/bar/>
+            Options +ExecCGI
+            Order allow,deny
+            Allow from all
+        </Directory>
+        AddHandler plp-document plp
+        Action plp-document /PLP_COMMON/plp.cgi
+    </IfModule>
