## What is Calcium++?

Calcium++ is a programming environment for learning to build code by blocks. If you are familiar with block-based programming such as Scratch, it is easy to begin coding in this app. The app can make a Python-like program.

Usage:
- This app needs internet connection.
- Drag blocks and tap the "Run" button on the upper left to execute a program.
- Long-tapping a block shows "duplicate" on the menu. It's useful for copying blocks.

For developers:
This app depends on open-source projects. Thank you, Blockly and Pyodide teams!
