+A reimplementation of the [Kilo](https://viewsourcecode.org/snaptoken/kilo/index.html)
+tutorial in Rust. 
 
 ## Implementation notes:
 * The `editor` prefix has been removed from all the editor methods. Since this implementation
@@ -10,6 +10,9 @@ uses `impl`s on a shared `Editor` struct, the prefix is redundant
 implemented in a more idiomatic Rust fashion.
 * Row structs are referenced by their index in the Editor struct, rather than as a direct reference in method calls. 
 This generally simplifies dealing with the rules of Rust (borrow checker).
+* The `prompt` method of the editor can not take an arbitrary formatting string, due to Rust requiring a string literal 
+for string formatting macros.
 
-### Known issues:
-* Tab key does not expand to an indent
+### Additions / Changes
+* Reverse coloring for search results, so comment types can have different colors
+* Two separate vectors are used to define the two types of keywords, rather than the weird pipe suffix
