+## 7. Deploy the cert to local weechat IRC client through fifo plugin
+
+Before you can deploy your cert, you must [issue the cert first](https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert).
+
+Then you can deploy now:
+
+```sh
+export DEPLOY_WEECHAT_PEM=~/.weechat/ssl/relay.pem
+export DEPLOY_WEECHAT_HOME=~/.weechat
+acme.sh --deploy -d weechat.example.com --deploy --deploy-hook weechat
+
+Notes:
+* Run acme.sh under the same user as the weechat client
+* Weechat must be configured with ```plugins.var.fifo.fifo = on```
+
+On deploy, the weechat deploy hook copies the the relevant data to $DEPLOY_WEECHAT_PEM.
+Additionally, this hook attempts to issue a ```/relay sslcertkey``` command via the FIFO
+plugin.  The FIFO files are searched for within $DEPLOY_WEECHAT_HOME.  Both environment
+variables default to weechat's defaults listed above.
+
+If successful, this installs and reloads the new relay SSL certificate in the
+client requiring no user interaction whatsoever.
