How do I build the QField source

I ran https://github.com/opengisch/QField build for Android using Powershell
with the following steps:
1.Install docker for windows
2.Execute Pull command at
https://hub.docker.com/r/opengisch/qfield-sdk/tags/
3. Run [git clone https://github.com/opengisch/QField.git] to download the
source locally
4. Execute [cd QField] and move to the downloaded folder
5. Run [git submodule init]
6. Run [git submodule update]
7. Run [docker run -v $(pwd):/usr/src/qfield docker.io/opengisch/qfield-sdk:
$TAG /usr/src/qfield/scripts/docker-build.sh --rm] , Enter the 2 QField SDK
tags in "$TAG"

7. I get the error "*** ERROR MISSING APP_VERSION OR APP_VERSION_CODE
ENVIRONMENT VARIABLE".
What kind of settings are needed to solve this?
