+After using YAML for a long time, for many, many Kubernetes manifest files, I have today learnt that it contains two multiline value types (called scalars):
+
+```yaml
+scalarsExample:
+    literalScalar: |
+        Literal scalars use the pipe (`|`) to denote the start of the value with the scope indicated by indentation.
+        All content here is used literally, with newlines preserved.
+        <-- This is the start of the line, the spaces before this aren't included in the literal.
+        This should be used when storing things like file contents (e.g. in a ConfigMap)
+    foldedScalar: >
+        Folded scalars use the greater-than symbol (`>`) to denote the start of the value with the scope indicated by indentation.
+        Unlike literal scalars newlines aren't preserved and instead converted into spaces. 
+        <-- This is the start of the line, the spaces before this aren't included in the value.
+        This should be used when you'd normally use a string but the contents are long and wrapping makes it easier to read.
+```
