JetBrains Fleet has limited description for setting.json reference offered in link, where toolchains field is merely described as "Enable toolchains for the folder or its subfolders".
The auto-generated setting.json is something like this:
{
"toolchains": []
}
I wonder the usage of toolchains and how to configure it, or where can I find a more detailed reference.
You can select toolchains in the UI settings for your project. Here are some examples (language specific):
