@ -3,4 +3,14 @@ Amaranth is a small drawing app written in Haskell. It was
created as a small learning project, and it probably won't
be continued.
This code is licensed with The Unlicense. Learn more at
https://unlicense.org/.
# ⚙️ How to use
Amaranth comes with two modes with which you can draw on
the screen:
- **brush mode**, which you can use by hitting B on the keyboard, and
- **eraser mode**, which you can use by pressing E.
# 📸 Screenshots
None by now. 😥
