+Open Bioinformatics Foundation (OBF) main website
+=================================================
+
+This git repository hosts static HTML for the OBF website, which
+GitHub pages serves at http://obf.github.io/ and which we will
+later point https://open-bio.org to. This is designed to replace
+the WordPress site used until 2025.
+
+This repository will host:
+
+* The front-page ``index.html``
+* The ``/board/`` and other misc content originally in WordPress
+
+Separate repositories handle other parts of the website:
+
+* https://github.com/OBF/wiki hosts the historical ``/wiki/`` content,
+  originally hosted in MediaWiki but converted to Markdown.
+* https://github.com/OBF/bosc2000 to https://github.com/OBF/bosc2016
+  host the ``/bosc2000/`` to ``/bosc2016`` content, static HTML in the
+  earlier meetings, later on just the PDFs like abstracts.
+
+Pending:
+
+* The ``/bosc/`` content originally in WordPress
+* The ``/wp-content/`` like photos
