+==== Loki
+
+Loki (https://grafana.com/oss/loki/) is a log aggregation system. The Decanter Loki appender is able to push collected data
+to Loki via the Push API.
+
+The Decanter Loki appender converts any kind of collected data (coming from the dispatcher) as a log string that can be stored in Loki.
+
+The `decanter-appender-loki` feature installs the Loki appender:
+
+----
+karaf@root()> feature:install decanter-appender-loki
+----
+
+This feature also adds `etc/org.apache.karaf.decanter.appender.loki.cfg` configuration file:

+
+* `loki.url` is the location of the Loki push API
+* `loki.tenant` is optional and define the tenant used to push data
+* `loki.username` and `loki.password` are used for basic authentication

+==== HDFS
+
+Decanter HDFS appender stores collected data into a HDFS file.
+
+The `decanter-appender-hdfs` feature installs the HDFS appender:
