error: experimental Nix feature 'nix-command' is disabled; use '--extra-experimental-features nix-command' to override

[tintin10q]

Describe the bug
When I tried to install I get error: experimental Nix feature 'nix-command' is disabled; use '--extra-experimental-features nix-command' to override

To Reproduce
Steps to reproduce the behavior:

1. Install nix
2. Run nix profile install github:srid/emanote

Expected behavior
I would expect the command to work. You like you suggest it will on your how to install page here https://emanote.srid.ca/start/install

Desktop (please complete the following information):

• Ubuntu 18.04.6 LTS

[tintin10q]

I had to run nix profile install github:srid/emanote --extra-experimental-features nix-command --extra-experimental-features flakes for it to work. If this is now what is needed you should update the installation guide.

[srid]

I will update that documentation page, but you need to enable flakes by following the instructions here: https://nixos.wiki/wiki/Flakes#Installing_flakes

[srid]

This part I think,

[tintin10q]

Ok I will try that

Thanks for updating this. Could you explain what the Nix cache does?

[srid]

Using the Nix binary cache will generally avoid compiling the software and its dependencies ... and instead, pull the built binaries directly from the binary cache specified. I'll add this to docs.

Can someone please explain what needs to be appended where?
I've just tried running nix search librewolf and it yielded a similar error.
I've tried adding extra-experimental-features = flakes to ~/.config/nix/nix.conf, but it didn't do anything
it would be really helpful if nix had this functionality, which someone unfamiliar with the project would expect to work out of the box work out of the box
