+Build the Collectd containers
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This is an optional step, if you do not wish to build the containers locally, please continue to `Download and run Collectd+Influxdb+Grafana containers`_.
+This step will build the container images locally, allowing for testing of new changes to collectd.
+This is particularly useful for the ``experimental`` flavour for testing PRs, and for building a ``collectd-6`` container.
+
+To run the playbook and build the containers, run::
+ sudo ansible-playbook docker/ansible/collectd_build.yml
+
+By default, all contaienrs will be built.
+Since this can take a while, it is recommended that you choose a flavor to build using tags::
+
+ sudo ansible-playbook docker/ansible/collectd_build.yml --tags='collectd-6,latest'
+
+The available tags are:
+
+* *stable* builds the ``barometer-collectd`` image
+* *latest* builds the ``barometer-collectd-latest`` image
+* *experimental* builds the ``barometer-collectd-experimental`` container, with optional PRs
+* *collectd-6* builds the ``baromter-collectd-6`` container, with optional PR(s)
+
+* *flask_test* builds a small webapp that displays the metrics sent via the write_http plugin
+
+.. note::
+ The flask_test tag must be explicitly enabled.
+ This can be done either through the ``--tags='flask_test'`` (to build just
+ this container) or with ``--tags=all`` to build this and all the other
+ containers as well.

+Anuket Barometer testing guide
+==============================
+
+This document will describe how to use different tests in this repo.
+
+There are a number of tools and scripts in Barometer that can be used for testing, whether that is during development, building, code reviews, or run regularly in CI.
+Some of the tests are automated, and cover building collectd, others cover particular plugins.
+
+.. TODO: This guide should also include how to manually verify that collectd plugins are working as expected.
+
+.. TODO: There might be some troubleshooting guide in here too.
+
+Porting collectd to version 6
+=============================
+
+Thre is an ansible playbook for building and running collectd 5 and 6 together to compare the collected metrics.
+This is intended to help test porting from collectd 5 to 6, and confirm equivalency across the versions.
+
+The playbook will::
+
+ * build collectd-6, collectd-latest and flask app containers
+ * generate a set of collectd configs
+ * launch the collectd-6, collectd-latest with the generated configs
+ * run the flask app which has a http server that receives metrics from
+ collectd v5 and collectd v6
+ * display the received metrics from both versions of collectd
+ Collectd v5 shows PUTVAL
+ Collectd v6 shows PUTMETRIC
+
+To run this comparison, use the following command::
+
+ $ cd docker/ansible/
+ $ sudo ansible-playbook -i default.inv collectd6_test.yml
+
+The playbook takes the following parameters:
+
+ * PR (optional)
+ The PRID for an upstream collectd pull request that will be
+ passed to the collectd 6 container build
+
+ * plugin (optional)
+ The name of the plugin that is bneing ported
+ This will filter the received metrics to show the value passed.
+
+To run the playbook with these configs, pass the extra var to ansible::
+
+ sudo ansible-playbook -i default.inv -e PR=<PR_ID> -e plugin=<plugin_name> collectd6_test.yml
+
+The metrics can then be viewed by inspecting the container logs or attaching to the container to view the output::
+
+ $ docker attach <webserver-container>
+ $ #OR
+ $ docker logs <webserver-container>
+
+Metrics from collectd 5 will appear preceeded with ``PUTVAL``, and metrics from collectd 6 will appear preceeded by ``PUTMETRIC``.
