+```
+docker run --name falcon-redis -p6379:6379 -d redis:4-alpine3.8
+```
 
-## Stop and Remove containers
+##### 3. Start falcon-plus modules in one container
+
+```
+    ## pull images from hub.docker.com/openfalcon
+    docker pull openfalcon/falcon-plus:v0.2.1
+    
+    ## run falcon-plus container
+    docker run -itd --name falcon-plus \

+
+    ## check status of backend modules
+    docker exec falcon-plus ./open-falcon check
+
