+This started as a little experiment, how far I can go with just a C

 ## Features
 
-* Load/Save/create text files
+* Load/Save/Create text files
 * Common keyboard controls
 * Search
-* Syntax Highlighting
+* Syntax Highlighting for C (so you can edit fuNote source IN fuNote)
+* Super small (23k binary)
+* No dependencies
+
+## Limitations
+
+* No UTF-8. If you open an UTF-8 file with only characters from the ASCII
+  table (most of English texts and source code), it works just fine
+  (because ASCII and UTF-8 are compatible in the "upper part" of the table),
+  but you will mess up your file when you are edit files with special
+  chars like ö in it.
