==first== 
download+install putty to your pc
download+install winscp to your pc

start menu type PuttyGen
hit generate
hit save private key
hit save public key
to somewhere safe, this will be like your encrypted password to the server. 
don't share the private key with anyone

if you don't have a text editor i would suggest visual studio code

==ssh key setup (server authentication)==
click compute engine in menu
go to Metadata in left menu
click sshkeys tab

if you don't still have puttygen open... open it back up and load your key
where it says public key for pasting into openssh authorized_keys
copy that and paste it into the browser

replace that with your username seen on above keys

==installing valheim server==
we will use this tool to make install easy
https://linuxgsm.com/lgsm/vhserver/

you don't need to make a separate account like they say in tutorial, it will make everyting harder.
we already have our admin account that is perfect for this.

=install dependencies
sudo dpkg --add-architecture i386; sudo apt update; sudo apt install curl wget file tar bzip2 gzip unzip bsdmainutils python util-linux ca-certificates binutils bc jq tmux netcat lib32gcc1 lib32stdc++6 steamcmd
=install the linux gsm script
wget -O linuxgsm.sh https://linuxgsm.sh && chmod +x linuxgsm.sh && bash linuxgsm.sh vhserver
=install the server
./vhserver install

=install nodejs
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt update && sudo apt install -y nodejs
=install gamedig
npm install gamedig -g

woo that was easy!

==configuring valheim server==
since we are using linux gsm to run this we will use their config files

=look at the default config file (in winscp double click it)
lgsm/config/_default.cfg

=and copy these lines 

servername="Valheim Server"
# Minimum password length is 5.
serverpassword=""
port="2456"
gameworld="${selfname}"
public="1"

=open safe place to config
lgsm/config-lgsm/vhserver/common.cfg

paste from above
change the values to what you would like
here's mines for example:

# this is the name it shows up on game list
servername="EXAMPLE"
# Minimum password length is 5.
serverpassword="ilikegames"
# if you change this you will need to update firewall rules
port="2456"
#this is the name of the world file
gameworld="20200218"
public="1"

save the file and winscp should automatically upload to the server for you.

==valheim server details==
take note of these file locations

=home directory
/home/yourusername
this is where everything is

=valheim world files
.config/unity3d/IronGate/Valheim
here's your world files in case you want to back them up
also your admin, ban, whitelist

=valheim server files
serverfiles folder.. lol
this is where the actual valheim install is

==running server
in your putty console window type
to see what you can do
./vhserver help

./vhserver start
./vhserver stop
./vhserver details

are the most useful

if you get in some weird state where you don't know whats going on 
sudo reboot
will reboot your server and you can call ./vhserver start again

==using existing world files
=find your world files .db .fwl
in windows it's C:\Users\YOURUSERNAME\AppData\LocalLow\IronGate\Valheim\worlds
or get them from your existing server
for example:
myserver.db myserver.fwl

=open winscp, connect to server, and go to worlds folder
/home/SERVERUSERNAME/.config/unity3d/IronGate/Valheim/worlds
drag your myserver.db myserver.fwl world files into the server folder to upload them

=change your config to use new world files
make sure your server is stopped
./vhserver stop

open your config file lgsm/config-lgsm/vhserver/common.cfg
change 
gameworld="myserver" 
(or whatever your world filename is)

now start the server and it should be using your existing world
./vhserver start
