+Experimental Docker file to run a Valheim server in a Raspberry Pi4
+
+## Requeriments:
+Raspberry Pi4: I only tested on a 8GB of RAM with the next requirements:
+- [RaspianOs 64 Bits](https://downloads.raspberrypi.org/raspios_arm64/images/raspios_arm64-2020-05-28/) updated.
+- Upgrade the distribution to Debian BullsEye (change the repositories to):
+
+    deb http://deb.debian.org/debian           bullseye main contrib non-free
+    deb http://deb.debian.org/debian-security/ bullseye-security main contrib non-free
+    deb http://deb.debian.org/debian           bullseye-updates main contrib non-free
+    
+    sudo apt update & sudo apt upgrade & sudo apt dist-upgrade
+    
+- Install [Podman](https://podman.io/getting-started/installation) v3.3.1 (Debian repository does not work correctly in my case).
+
+## Create the image (it will take around 1-2 hours)
+
+    podman build -f Valheim.dockerfile
+    podman 
+        
+## Execute the container
+In my case, I have my world from previous server in /home/pi/valheim_data.
+
+    podman run --name valheim --network host -v /home/pi/valheim_data:/root/valheim_data:rw -it valheim-base /bin/bash
+    
+Create a start.sh copy from the start_server.sh and modify the execution with box64 in front
+For example I execute my server with the next line to create a local network server to play at home.
+    
+    box64 ./valheim_server.x86_64 -public 0 -nographics -batchmode -name "Your server Name" -port 2456 -world "Your Workd Name" -savedir "/root/valheim_data"
+    
+## Considerations:
+Pi4 has a limited hardware, it this is emulating x86_64 over arm64, so don't expect so high performance. It works, I didn't have any problems playing some hours.
+When the game saves it freeze all connections during some seconds, take it into account!!!!!
+
+## This experiment can be done for the next projects:
+podman
