+# Basic example
+
+This is a basic example of what can do Katenary with standard docker-compose file.
+
+In this example:
+
+- `depends_on` yield a `initContainer` in the webapp ddeployment to wait for database
+- so we need to declare the listened port inside `database` container as we don't use it with docker-compose- also, we needed to declare that `DB_HOST` is actually a service name
+
+Take a look on [chart/basic](chart/basic) directory to see what `katenary convert` command has generated.
