Hello dear members,
Since yesterday, I have been trying to install open VPN server on my droplet in vain.
This is what I wanted to with it.

I wanted to have a VPN that can allow me to access different website with different IP addresses.
However, I'm not sure how to implement this. I'm a first year IT student(I'm yet to master a few tricks).
I was able to install openvpn and RSA, but I was** not able to extract **server.conf file to edit on a text editor using

apt-get update
apt-get upgrade
apt-get install openvpn easy-rsa

The command I used to extract the file:

gunzip -c /usr/share/doc/openvpn/examples/sample-config-files/server.conf.gz > /etc/openvpn/server.conf

Output: bash: / : is a directory.

My question is where does the extracted file go? How can access it?
How can I implement the VPN such that I can use a new ip of a droplet of my choice?
How can I add new users with/without root access?
which plan should I use for better speeds?
I'm running windows operating system

Sorry for my poor grammar.

Thanks in advance for your assistance.
