 On distributions which have SELinux enabled out-of-the-box you will need to either re-context the files or set SELinux into Permissive mode in order for docker-elk to start properly.
 For example on Redhat and CentOS, the following will apply the proper context:
 
-````bash
+```bash
 .-root@centos ~
--$ chcon -R system_u:object_r:admin_home_t:s0 fig-elk/
-````
+-$ chcon -R system_u:object_r:admin_home_t:s0 docker-elk/

+## Increase max_map_count on your host
+
+You need to increase `max_map_count` on your Docker host:
+
+```bash
+$ sudo sysctl -w vm.max_map_count=262144
+```
