+# Docker examples for lamassu
+
+This directory contains docker-compose examples for lamassu.
+
+## Usage
+
+Make sure you have built lamassu (check for jar file in `..target/`).
+
+Edit `application-config/feedproviders.yml` so that it contains at least one source feed.
+
+The run docker-compose:
+
+    docker-compose -f docker-compose-simple.yml up
+
+or
+
+    docker-compose -f docker-compose-advanced.yml up
+
+The difference between simple and advanced is that simple runs a single instance of lamassu, whereas
+advanced runs two instances, one which is responsible for fetching data from upstream sources and updating
+caches (leader), and one which responds to API requests. The second instance may be scaled horizontally, but
+the leader can only have one instance, and must be scaled vertically if needed.
