+## 10. Deploy the cert to HAProxy
+
+You must specify the path where you want the concatenated key and certificate chain written.
+```sh
+export DEPLOY_HAPROXY_PEM_PATH=/etc/haproxy
+```
+
+You may optionally define the command to reload HAProxy. The value shown below will be used as the default if you don't set this environment variable.
+
+```sh
+export DEPLOY_HAPROXY_RELOAD="/usr/sbin/service haproxy restart"
+```
+
+You can then deploy the certificate as follows
+```sh
+acme.sh --deploy -d haproxy.example.com --deploy-hook haproxy
+```
+
+The path for the PEM file will be stored with the domain configuration and will be available when renewing, so that deploy will happen automatically when renewed.
