+
+Femcode supports basic error handling using `Twink` (try) and `Bimboy` (except) blocks.
+
+```femcode
+Twink Femboycore
+    # Code that might cause an error
+    result is 10 / 0 # This will cause a division by zero error

+### Compound Assignment Operators
+
+Shorthand operators for common assignment operations:
+
+*   `+=` (add and assign)
+*   `-=` (subtract and assign)
+*   `*=` (multiply and assign)
+*   `/=` (divide and assign)

+### Increment/Decrement Operators
+
+*   `++` (increment by 1)
+*   `--` (decrement by 1)
+
+```femcode
+value is 10
+value++ # Equivalent to: value is value + 1
