From 243ce68ac6958c85856d4081b7ae08bbaed25047 Mon Sep 17 00:00:00 2001 From: Logan Campbell Date: Wed, 23 Jul 2014 22:47:03 +1000 Subject: [PATCH] Changed the README to Github markdown I've introduced syntax highlighting and headings. This should make the README easier for people to skim through to grab the code that they need to get started with this great project. --- README => README.markdown | 44 +++++++++++++++++++++++++++++++-------- 1 file changed, 35 insertions(+), 9 deletions(-) rename README => README.markdown (70%) diff --git a/README b/README.markdown similarity index 70% rename from README rename to README.markdown index 4758475..5781b48 100644 --- a/README +++ b/README.markdown @@ -1,4 +1,4 @@ -The Clojure debug-repl +# The Clojure debug-repl Every time I stick a println into some Clojure code to debug it, I think to myself, "This is Lisp!
