+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
+  at: https://github.com/nushell/engine-q/issues/522

 # Nu-Engine
+
 Nu-engine handles most of the core logic of nushell. For example, engine handles:
-    - Passing of data between commands
-    - Evaluating a commands return values
-    - Loading of user configurations
+
+- Passing of data between commands
+- Evaluating a commands return values
+- Loading of user configurations
 
 ## Top level introduction
 The following topics shall give the reader a top level understanding how various topics are handled in nushell.
