This is already mentioned in our user guide: https://github.com/input-output-hk/cardano-wallet/wiki/Wallet-command-line-interface

Also, I'd rather give the command to generate the auto-completion scripts than the scripts themselves, don't you think ?

That's only for bash afais.

I think either is fine. I don't have a strong opinion, but it seems the upstream doc suggests to ship the output:
https://github.com/pcapriotti/optparse-applicative/wiki/Bash-Completion#introduction

Normally, the output of --bash-completion-script should be shipped with the program and copied to the appropriate directory (usually /etc/bash_completion.d/) during installation.

Personally, I think this makes more sense than having it in the wiki. Nice to have zsh + fish too! 🙏

We should generate the completion scripts for all shells for all programs when building the release archives. This could be done with nix or travis - choose your poison.

That will be more helpful to users than having these scripts in either the git repo or the wiki.

[hasufell]

@rvl are you gonna take a shot at that? I'm not familiar with either of those.

[rvl]

I can coach you if you have time. Travis is just glorified shell scripts embedded in YAML. Nix is just shell scripts embedded in an obscure functional language - start looking in nix/linux-release.nix.

Discussed in DMs with @hasufell on Slack. Approving my own changes on his behalf.
