+If you see any issues with the Pygments syntax highlighting for Nimrod (what github uses) please list them here so that somebody can fix them at some point.
+
+## Incorrect type suffix highlighting
+
+Type suffixes with an apostrophe are highlighted correctly, but the manual states that they are optional:
+
+```nimrod
+var x = 0f64 # This is red.
+```
