With the `tutor` command, you'll be able to learn a lot about how Nushell
works along with many fun tips and tricks to speed up everyday tasks.
To get started, you can use `tutor begin`.

Engine-q is the upcoming engine for Nushell. Build for speed and correctness,
it also comes with a set of changes from Nushell versions prior to 0.60. To
get ready for engine-q look for some of these changes that might impact your
current scripts:
* Engine-q now uses a few new data structures, including a record syntax
that allows you to model key-value pairs similar to JSON objects.
* Environment variables can now contain more than just strings. Structured
values are converted to strings for external commands using converters.
* `if` will now use an `else` keyword before the else block.
* We're moving from "config.toml" to "config.nu". This means startup will
now be a script file.
* `config` and its subcommands are being replaced by a record that you can
update in the shell which contains all the settings under the variable
`$config`.
* bigint/bigdecimal values are now machine i64 and f64 values
* And more, you can read more about upcoming changes in the up-to-date list
