+== What is Apache Druid?
+Apache Druid is a fast and modern analytics database.
+Druid is designed for workflows where fast ad-hoc analytics, instant data visibility, or supporting high concurrency is important.
+As such, Druid is often used to power UIs where an interactive, consistent user experience is desired.
+
+== Druid High Level Architecture
+
+Druid’s core design combines ideas from data warehouses, timeseries databases, and search systems to create a high performance real-time analytics database for a broad range of use cases. Druid merges key characteristics of each of the 3 systems into its ingestion layer, storage format, querying layer, and core architecture.

Review comment:
       However it might be a good idea not to reference these images on the website cause this way the presentation only works online and if the website ever changes, the presentation will be broken.
