Create .tool-versions it is the asdf version manager config file

[am0o0]

the current FE is compatible with nodejs 16.14.2 so it is good to use this version with asdf version manager for having easier setup
the asdf setup instruction that I suggest we should add to README:

1. install it with help of https://asdf-vm.com/guide/getting-started.html
2. install nodejs plugin for asdf

asdf plugin add nodejs https://github.com/asdf-vm/asdf-nodejs.git

3. install compatible nodejs version with asdf

asdf install nodejs 16.14.2

4. reset the current terminal session to apply changes.

after setup asdf, if you enter node -v in dnsFookup dirs and subdirs, it must give you v16.14.2 in output.

we can skip having this config file and instead in the instructions we add one more step:

asdf local nodejs 16.14.2

do you want to i add a RunFE.sh file to automate running the FE?
