 Make sure to browse the help messages of these commands. They contain fully functional examples thanks to pointing at www.example.com.
 
+## Examples results are now shown in `help` pages ([amtoine](https://github.com/nushell/nushell/pull/8189))
+
+When commands define expected results for their examples, the output is now shown just below the associated examples.
+
+Let's take the `merge` command as an example!
+
+Before the change, the output of `help merge` would give
+
+```bash
+Examples:
+  Add an 'index' column to the input table
+  > [a b c] | wrap name | merge ( [1 2 3] | wrap index )
+
+  Merge two records
+  > {a: 1, b: 2} | merge {c: 3}
+
+  Merge two tables, overwriting overlapping columns
+  > [{columnA: A0 columnB: B0}] | merge [{columnA: 'A0*'}]
+```
+
+Now, it gives the output of all the example commands:
+
+```bash
+Examples:
+  Add an 'index' column to the input table
+  > [a b c] | wrap name | merge ( [1 2 3] | wrap index )
