+# Projects
+These projects should all run on the Cardputer in CircuitPython. Extra libraries may be needed from the CircuitPython library bundle - import errors will tell you what you need :P
+
+When using a file in CircuitPython, it needs to be renamed to "code.py" as this is what cPy will look for when running. 
+
+## Text Editor
+A mostly functional, but incredibly basic text editor.
+### Features
+- Cursor-less text editing (remember how Minecraft book writing used to feel like? Yeah. That.)
+- Save file - You have to type in the filename and extension yourself. The good news is the "." key works on this screen.
+- Open file - You can select from a list of files in the SD card. Still no line scrolling here, so only the first 7 files will be visible
+- If you open a file, the save menu conveniently fills in the filename for you, so you don't have to write it again to re-save.
+### Dependencies
+- Keyboard library from this repository
+- adafruit_display_text from the bundle
+### Issues
+- No line scrolling. Once you exceed 7 lines, you're guessing, bud
+- No folder support. Selecting folders in the SD card folder will break it.
+- There are no confirmation or warning messages. Use with caution and be sure that you aren't using a repeat filename, or it will overwrite the file without warning.
