Minimum Requirements you will need to be able to run a server and play it from the same machine=
8gb of ram
2 cores 2.7ghz
ssd with 1.5gb space

you will need to google steam cmd download
then download it
make a folder on your desktop named gone fishing server
drag the steam cmd exe you have just downloaded into the folder you made on the desktop
run the exe and it will auto download and add files needed into the folder
once it gets to 100%
you can type this
login anonymous
then type this
update_app 3645890
hit enter
it will the update the gone fishing app on your steam adding the server files into the folder you have made
once it gets to 100% and says app updated
just type exit and hit enter and it will close down
right click on the server config and open with note pad or with note ++
you will see values you can change
server name
public
players
change these to whatever you want and then save and exit
run the server bat.exe and a console will open with server starting
once its started you will be able to join your server

Port forwarding so others can join

login to your router and add ports, google the gone fishing ports if unsure
restart router and they will be added
and finally go to your windows security and add inbound and outbound ports for gone fishing
hope this helps
