comes from the SSLlabs client API via ``update_client_sim_data.pl``
The whole process is done manually.
## Instructions how to add a client simulation:
* Start wireshark at a client or router. Best is during capture to filter for the target of your choice.
* Make sure you create a bit of encrypted traffic to your target. Attention, privacy: if you want to contribute, be aware that the ClientHello contains the target hostname (SNI).

* Make sure the client traffic is specific: For just "Android" do not use a browser! Be also careful with Google Apps, especially on older devices as they might has an own TLS stack
* Stop recording.
