 Setup
 =====
-This section is incomplete.
+#. Install and run Elasticsearch and Gearman
+#. Install ``php-gearman``
+#. Get a local copy of the code::
+
+     $ git clone https://git.cweiske.de/phinde.git phinde
+
+#. Install dependencies via composer::
+
+     $ composer install
+
+#. Point your webserver's document root to phinde's ``www`` directory
+#. Copy ``data/config.php.dist`` to ``data/config.php`` and adjust it.
+   Make sure your add your domain to the crawl whitelist.
+#. Run ``bin/setup.php`` which sets up the Elasticsearch schema
+#. Put your homepage into the queue::
+
+     $ ./bin/process.php http://example.org/
+
+#. Start at least one worker to process the crawl+index queue::
+
+     $ ./bin/phinde-worker.php
+
+#. Check phinde's status page in your browser.
+   The number of open tasks should be > 0, the number of workers also.
+
+
+Re-index when your site changes
+===============================
+When your site changed, the search engine needs to re-crawl and re-index
+the pages.
+
+Simply tell phinde that something changed by running::
+
+    $ ./bin/process.php http://example.org/foo.htm
+
+phinde supports HTML pages and Atom feeds, so if your blog has a feed
+it's enough to let phinde reindex that one.
+It will find all linked pages automatically.
+
+
+Website integration
+===================
+Adding a simple search form to your website is easy.
+It needs two things:
+
+- ``<form>`` tag with an action that points to the phinde instance
+- Search text field with name of ``q``.
+
+Example::
+
+  <form method="get" action="http://phinde.example.org">
+    <input type="text" name="q" placeholder="Search text"/>
+    <button type="submit">Search</button>
+  </form>
+
+
+System service
+==============
+When using systemd, you can let it run multiple worker instances when
+the system boots up:
+
+#. Copy files ``data/systemd/phinde*.service`` into ``/etc/systemd/system/``
+#. Adjust user and group names, and the work directories
+#. Enable three worker processes::
+
+     $ systemctl daemon-reload
+     $ systemctl enable phinde@1
+     $ systemctl enable phinde@2
+     $ systemctl enable phinde@3
+     $ systemctl enable phinde
+     $ systemctl start phinde
+#. Now three workers are running. Restarting the ``phinde`` service also
+   restarts the workers.
+
+
 
 Cron job
 ========
 Run ``bin/renew-subscriptions.php`` once a day with cron.
+It will renew the WebSub subscriptions.
+
+
+=====
+Howto
+=====
+
+Delete index data from one domain::
+
+    $ curl -iv -XDELETE -H 'Content-Type: application/json' -d '{"query":{"term":{"domain":"example.org"}}}' http://127.0.0.1:9200/phinde/_query
+
+That's delete-by-query 2.0, see
+https://www.elastic.co/guide/en/elasticsearch/plugins/2.0/delete-by-query-usage.html
