+## Wekan for RasPi3 arm64 and other CPU architectures
+
+- Ubuntu 18.04 Server arm64 for RasPi3
+- Has MongoDB 3.6.x running
+
+Note: Raspbian is not recommended, because it is 32bit and has 32bit MongoDB that has file size limit of 2 GB, if it grows bigger then it gets corrupted. That's why here is arm64 version of Ubuntu 18.04.
+
+### Download
+
+.7z size 876 MB, unarchived RasPi3 .img size of 4.5 GB:
+
+https://releases.wekan.team/raspi3/wekan-2.94-raspi3-ubuntu18.04server.img.7z
+
+Or alternatively Wekan Meteor 1.8.1 bundle for arm64:
+
+https://releases.wekan.team/raspi3/wekan-2.94-arm64-bundle.tar.gz
+
+### How to use .img
+
+1) Write image to SD card
+```
+sudo apt-get install p7zip-full
+7z x wekan-2.94-raspi3-ubuntu18.04server.img.7z
+sudo dd if=wekan-2.94-raspi3-ubuntu18.04server.img of=/dev/mmcblk0 conv=sync status=progress bs=100M
+```
+
+At first boot disk image expands to full SD card size.
+
+2) Login for Wekan files
+- Username wekan
+- Password wekan (for Wekan files)
+
+(Or for ubuntu user: username ubuntu password ubuntuubuntu)
+
+3) After login as wekan user, check IP address with command:
+```
+ip address
+```
+4) Change that IP addess to start-wekan.sh:
+```
+cd repos
+nano start-wekan.sh
+```
+There change ROOT_URL to have your IP address. Save and Exit: Ctrl-o Enter Ctrl-x Enter
+
+5) Start Wekan:
+```
+./start-wekan.sh
+```
+6) On other computer, with webbrowser go to http://192.168.0.12 (or other of your IP address you changed to start-wekan.sh)
+
+### How to use bundle
+
+1) On any Ubuntu 18.04 arm64 server:
+```
+wget https://releases.wekan.team/raspi3/wekan-2.94-arm64-bundle.tar.gz
+tar -xzf wekan-2.94-arm64-bundle.tar.gz
+sudo apt-get install build-essential curl make nodejs npm mongodb-clients mongodb-server
+sudo npm -g install npm
+sudo npm -g install n
+sudo n 8.16.0
+sudo systemctl start mongodb
+sudo systemctl enable mongodb
+wget https://releases.wekan.team/raspi3/start-wekan.sh
+nano start-wekan.sh
+```
+There edit [ROOT_URL to have your IP address or domain, and PORT for your localhost port](https://github.com/wekan/wekan/wiki/Settings). 
+
+You can also allow node to run on port 80, when you check where node is:
+```
+which node
+```
+and then allow it:
+```
+sudo setcap cap_net_bind_service=+ep /usr/local/bin/node
+```

+### How this was done
+
+1) Bundle at https://releases.wekan.team/raspi3/ was created this way originally on Xubuntu 19.10 x64:
+```
+git clone https://github.com/wekan/wekan
+cd wekan
+git checkout meteor-1.8
+./rebuild-wekan.sh
+# 1 and Enter to install deps
+./rebuild-wekan.sh
+# 2 and Enter to build Wekan
+cd .build
+```
+Then create tar.gz that included bundle directory, with name wekan-VERSION.tar.gz
+
+Ready-made bundles of Meteor 1.6 Wekan x64 at https://releases.wekan.team
+
+Ready-made bundle of Meteor 1.8 Wekan for arm64 at https://releases.wekan.team , works at RasPi3, and any other arm64 server that has Ubuntu 18.04 arm64.
+
+2) Ubuntu Server for RasPi3 from https://www.raspberrypi.org/downloads/
+
+Write to SD card.
+
+Boot:
+- Username ubuntu
+- Password ubuntu
+- It asks to change password at first boot.
+
+3) Create new user:
+```
+sudo adduser wekan
+```
+Add name wekan, password wekan, and then other empty with Enter, and accept with Y.
+
+4) Add passwordless sudo:
+```
+export EDITOR=nano
+sudo visudo
+```
+There below root add:
+```
+wekan  ALL=(ALL:ALL) NOPASSWD:ALL
+```
+Save and Exit: Ctrl-o Enter Ctrl-x Enter
+
+5) Logout, and login
+
+- Username wekan
+- Password wekan
+
+6) Download your Wekan x64 bundle
+
+```
+wget https://releases.wekan.team/wekan-VERSION
+
+sudo umount /dev/mmcblk0p1 /dev/mmcblk0p2
+ Requirements for any CPU architecture:
+- Has Node.js, NPM and MongoDB
+- https://github.com/wekan/wekan master branch has Meteor 1.6, requires Node 8.16.0, and MongoDB 3.2.x or earlier
+- https://github.com/wekan/wekan meteor-1.8 branch has Meteor 1.8.x, requires Node 8.16.0, MongoDB 3.6.x or newer, for example MongoDB 4.0.10 work too.

+## Unmount SD card partitions:
+# sudo umount /dev/mmcblk0p1 /dev/mmcblk02
+## Read SD card to image:
+# sudo dd if=/dev/mmcblk0 of=wekan-2.94-raspi3-ubuntu18.04server.img conv=sync status=progress
+## Resize image to smaller from 32 GB to 4.5 GB:
+# sudo ./resize.sh wekan-2.94-raspi3-ubuntu18.04server.img
+## Make .7z archive to pack about 4.5 GB to about 800 MB:
+# 7z a wekan-2.94-raspi3-ubuntu18.04server.img.7z wekan-2.94-raspi3-ubuntu18.04server.img
