+This is the source code for <http://perl6.org/>.
+
+It is rendered with [mowyw](http://perlgeek.de/en/software/mowyw)
+every 15 minutes, so updates to the repository should also result in
+an update of perl6.org. If not, talk to moritz on #perl6.
+
+Here are some guidelines that you should respect when changing this site:
+
+  * Only link to up-to-date information. Feel free to delete outdated
+    information — it is often more confusing than helpful.
+
+  * Be nice.
+
+  * Don't hesitate to link to pages you wrote youself, if they are helpful to
+    a broader Perl 6 audience.
+
+  * If you have a Perl 6 blog, get it included in the planetsix.perl.org feed
+    instead. Talk to \[Coke\] on #perl6.
+
+  * If you intend to change the layout, consider what happens when:
+
+      - user's viewport is small (e.g. 800x600)
+      - user resizes window
+
+  * Test any layout changes on browsershots.org, with particular consideration
+    to badly broken browsers. IE6 still needs to be considered (2009-07).
+    IE5.5 and below can be ignored.
+
+  * We spell "Perl 6" consistently with a non-breaking space. If you don't have
+    already, go get an editor with decent Unicode support.
+
+  * Speaking of which, all pages are served as UTF-8.
+
+  * If you create a new page, please link to the URL without the
+    ".html" extension.
