+# Kusaba X Database Migration
+
+## About
+This script pulls board information, posts and images from an already existing [Kusaba X][k] installation and replicates them in [Tinyboard][o]. It should be helpful for those who already use Kusaba X][k], and want to switch over to Tinyboard.
+[o]: http://tinyboard.org/
+[k]: http://kusabax.cultnet.net/
+
+## Requirements
+ 1. [Tinyboard][o] >= v0.9.2
+
+## Use
+ 1. Install Tinyboard (>= v0.9.2) normally.
+ 2. Download and place `kusabax.php` in the root folder of Tinyboard.
+ 3. Edit the script and fill in your Kusaba X configuration. You can find KU_RANDOMSEED from Kusaba X's config.php file.
+ 4. Run the script in a web browser.
+
+## Documentation
+Visit the Tinyboard development wiki at <http://tinyboard.org/wiki/> for help.

+## License
+See [LICENSE.md][l] for the license.
