OPENVPN client config

[cadteach]

I'm trying to setup a OPENVPN setup on my network, but don't really understand all the parts. My router (TPLINK 1750) has a OPENVPN setting, and I am trying to use that. I watched a video explanation, which showed an example setup. My question is on the client side. The router has a export for a .OVPN file, which is basically a text file. This file contains the first section which I assume is standard configuration stuff:

View OriginalClient config

client
dev tun
proto udp
float
nobind

..etc. It then contains a section:
<ca>
-----BEGIN CERTIFICATE-----
xxxxx
xxxxx
</ca>

and another section for <cert> </cert> and <key></key>. I assume these are all keys used as part of the configuration.

My question is, when setting up the client side, I used the full file as the .ovpn config file, but should I instead have saved these keys in a separate file or files? In otherwords, do I need to create a file called CA.CRT and put the key in there, and if so, exactly how is it formatted, and does it contain just that one key or all three keys?

I guess I thought it (the client side install) would create these from the config file, but I can't get it to run on any machine, windows based, linux based or otherwise (ARM type machine) I don't understand what files need to be created and what directories they go in.

The .OVPN file can be used as it is.
