+# Language repository
+
+This repository contains small examples for a simple function in several
+different programming languages. Feel free to play around with them, and modify
+them somehow!
+
+## Change ideas
+
+Here are some examples of how you can try to play around with these languages.
+What you decide to do is entirely up to you! These are just some examples for
+you to take inspiration from.
+
+- Change the manipulate-function to only add items if the value is even
+- Change the manipulate-function to print the values while adding them
+- Implement Fizz Buzz:
+  - A function takes a container with integers
+    - Loop through the container
+      - If the value is evenly sivisible with 3 and 5:
+        - Print "Fizz Buzz"
+      - If the value is only evenly divisible with 3:
+        - Print "Fizz"
+      - If the value is only evenly divisible with 5:
+        - Print "Buzz"
+      - Else, print the number itself
+- Take the container of integers, and returns the same values in a new container
+  but converted to strings
