 # OpenWifi OWLS Docker Compose
 ## Deployment with self-signed certificates
-To run a load simulation you need to generate a Digicert-signed AP certificate which will be used to connect to the gateway. The certificate common name (which will be your simulator ID) has to start with the digits `53494d`, so therefore when you generate your AP certificate the mac address has to start with `53:49:4d`. The rest of the address and the specified redirector URL can be chosen randomly. You only need to generate one AP certificate for your simulations.  
+To run a load simulation you need to generate a specific Digicert-signed AP certificate which will be used to connect to the gateway. The certificate serial number has to start with the digits `53494d` since otherwise the gateway won't allow a load simulation. The rest of the serial number and the specified redirector URL can be chosen randomly. You only need to generate one AP certificate for your simulations.  
 Be aware that since the OWLS deployment partly exposes the same ports on the host as the OpenWifi deployment, it is not intended that both run on the same host.
 1. Copy or move your AP load simulation certificate into the `docker-compose/certs` directory. Don't forget to name the files `device-cert.pem` and `device-key.pem` or adapt the path names in the OWLS configuration if you're using different file names.
-2. To be able to run load simulation tests against your OpenWifi SDK deployment, you'll have to [allow your simulator ID in the OWGW configuration](https://github.com/Telecominfraproject/wlan-cloud-owls#prepare-your-openwifi-gateway). You can do that by either editing [owgw.env](../owgw.env) or doing the changes directly in your OWGW configuration file if it is exposed on your Docker host.
+2. To be able to run load simulation tests against your OpenWifi SDK deployment, you'll have to [add the serial number of your generated AP certificate to the gateway configuration](https://github.com/Telecominfraproject/wlan-cloud-owls#prepare-your-openwifi-gateway). You can do that by either editing [owgw.env](../owgw.env) or doing the changes directly in your OWGW configuration file if it is exposed on your Docker host.
 3. Switch into the project directory with `cd docker-compose/owls`.
 4. Add an entry for `openwifi-owls.wlan.local` in your hosts file which points to `127.0.0.1` or whatever the IP of the host running the OWLS deployment is.
 5. Spin up the deployment with `docker-compose up -d`.
