+# SC-55 Tools
+Simple ass tools for creating Roland SC-55 (and maybe SC-88(Pro/20)??? Don't have emulator for that.) exclusive SysEx commands for art and text.
+
+## Installation
+It's as simple as cloning this repository or downloading the ZIP file.
+
+sc55text.py - should work right out of the box.
+
+sc55art.py - requires Pillow to be installed. (not doing requirements.txt for one fricking thing)
+
+## Usage
+Using sc55text.py:
+`python sc55text.py [your text here]`
+
+Using sc55art.py:
+`python sc55text.py <path to your image>`
+
