 ### Docker Hub image
 
 - pull docker image from docker hub: `docker pull diogopms/monit-docker-kubernetes`
 - start monit: `docker run -ti -p 2812:2812 -v $(pwd)/monitrc:/etc/monitrc diogopms/monit-docker-kubernetes`
 - create a docker container:
 
 ```
+#Normal mode (support slack and pushover)
 docker run -it \
   -p 2812:2812 \
   -v $(pwd)/monitrc:/etc/monitrc \
   -e "SLACK_URL=<SLACK_URL>" \

 ### Troubleshooting
 
 If when starting Monit returns the following message: `The control file '/etc/monitrc' permission 0755 is wrong, maximum 0700 allowed`, simply give the appropriate permissions to _monitrc_: `chmod 700 monitrc`.
