+Instructions to use
+To enable it you will need to configure Nginx Proxy Manager as Below then do the following
+
+Enable the following environment Variable by setting it to 1.
+| Variable       | Description                                  | Default |
+|----------------|----------------------------------------------|---------|
+|`CROWDSEC_BOUNCER`| When set to `1`, Crowdsec bouncer will be enabled.  This is needed when you want to block hosts using crowdsec. | `0` |
+
+Starting the container at this point will start Nginx-Proxy-Manager as before but will create a new file in /config/ called crowdsec-openresty-bouncer.conf
+
+You will need to edit this file with at least the following changes
+
+```
+API_URL=http://<crowdsecserver>:8080
+API_KEY=<APIKEY>
+```
+
+the crowdsec api key can be generated on the crowdsec instance using the following command 
+
+```
+cscli bouncers add npm-proxy
+```
+
+Currently this is a side project and I will try keep this up to date
