+Homebrew formula for v8 JavaScript engling and semi-automated script to update it
+==============================
+
+Prerequisites
+-------------
+
+You need up to date homebrew and supported OS X
+
+Refreshing formula
+------------------
+
+The process is very much automated and the following command can be used to update formula to desired v8 version.
+
+    ./load_deps.py <v8 version>
+
+Installing v8
+-------------
+
+You can install it a same way as other Hombrew formulae:
+
+    brew install v8.rb
