+collection.cgi
+--------------
+ Sample CGI script that creates graphs on the fly. The Perl modules `RRDs'
+(Debian package `librrds-perl'), `URI:Escape' (package liburi-perl),
+`HTML::Entities' (package libhtml-parser-perl) and a CGI capable web server
+(e.g. apache2 or boa) are needed. Simply install the script to a place where
+the webserver will treat it as a CGI script (/usr/lib/cgi-bin/ by default) and
+visit that page in a browser (http://localhost/cgi-bin/collection.cgi by
+default). Please refer to your webserver's documentation for more details.
+
+ Starting with version 4, collection.cgi requires a small config file, which
+should look something like this:
+
+ datadir: "/var/lib/collectd/rrd/"
+ libdir: "/usr/lib/collectd/"
+
+docker/
+-------
+Sample docker setup using an LD_PRELOAD wrapper to redirect system calls
+accessing /proc and /sys to prefixed bind-mounts inside the container.
+
+Drop your collectd configuration snippets in the
+contrib/docker/collectd.conf.d/ directory, and build an image including them:
+ $ docker build -t my_collectd ./contrib/docker/
+
+Then run it with the required bind-mounts:
+ $ docker run -it --rm \
+ -v /proc:/rootfs/proc:ro -v /sys:/rootfs/sys:ro \
+ --name collectd my_collectd
+ $ docker exec -it collectd collectdctl listval
