+The exporter (r69 and earlier) has been completely replaced. Please ensure you have removed the io_three_mesh addon from your Blender addons directory before installing the current addon (io_three).
 
 ## Installation
 
-Copy the io_mesh_threejs folder to the scripts/addons folder. If it doesn't exist, create it. The full path is OS-dependent (see below).

 Once that is done, you need to activate the plugin. Open Blender preferences, look for
 Addons, search for `three`, enable the checkbox next to the `Import-Export: three.js format` entry.

utils/exporters/blender/tests/README.md

+# Running tests
+In order to use the test scripts you must have your shell setup to execute Blender from the command line using `$ blender`. This either done by setting up your own wrapper scripts or by symlinking /usr/bin/python directly to $BLENDER_ROOT/blender. 
+
+## OS X
+Make sure your do not point to blender.app as it will not pass the arguments corrently. It is required to execute on $BLENDER_ROOT/blender.app/Contents/MacOS/blender in order for the tests to execute correctly.
+
+# Testing
+Each test script focuses on a specific context and feature of the exporter. 
+
+## Context
+Context determines whether an entire scene is being exported or a single mesh node.
+
+## Features
+Features should be tested separately (whenever possible), example: animations should be tested separately from bump maps.
+
+## Review
+When a test is executed a new root directory, if it doesn't already exist, is created at three.js/utils/exporters/blender/tests/review. Inside will contain subdirectories of each test (named the same as the script but with the `test_` prefix removed. The test directory will contain the exported JSON file(s), index.html, and textures (if textures are being tested). The index.html is already setup to source the required libraries and load the JSON file. There is nothing else that a user should need to do in order to test their export.
+
+The review directory has been added to the .gitignore and will not be included when committing changes.
