 Graphouse
 ---------
 - Add ClickHouse debian repo. [See doc.](https://clickhouse.yandex/reference_en.html#Installing)
 - [Install JDK8.](https://tecadmin.net/install-oracle-java-8-ubuntu-via-ppa/)
 - Install Graphouse `sudo agt-get install graphouse`
-- Set `graphouse.clickhouse.retention-config` property in graphouse config /etc/graphouse/graphouse.properties. You can skip this step, then [default config](../src/main/java/ru/yandex/market/graphouse/retention/DefaultRetentionProvider.java#L29) will be used
-- Start graphouse `sudo /etc/init.d/graphouse start`

 Graphite-web
 ------------
 - Install [graphite-web](http://graphite.readthedocs.io/en/latest/), if you don't have it already. You don't need carbon or whisper, Graphouse and ClickHouse completely replace them.
-- Add graphouse plugin `/opt/graphouse/bin/graphouse.py` to your graphite webapp root dir.
+- Add Graphouse plugin `/opt/graphouse/bin/graphouse.py` to your Graphite webapp root dir.
 For example, if you dir is `/opt/graphite/webapp/graphite/` use command below
 ```bash
 sudo ln -fs /opt/graphouse/bin/graphouse.py /opt/graphite/webapp/graphite/graphouse.py
