-# hyprcursor
+## hyprcursor
 The hyprland cursor format, library and utilities.
+
+Please note it's in very early development.
+
+## Why?
+
+XCursor sucks, and we still use it today.
+ - Scaling of XCursors is horrible
+ - XCursor does not support vector cursors
+ - XCursor is ridiculously space-inefficient
+
+Hyprcursor fixes all three. It's an efficient cursor theme format that
+doesn't suck as much.
+
+### Notable advantages over XCursor
+ - Automatic scaling according to a configurable, per-cursor method.
+ - Support for SVG cursors (soon, see todo)
+ - Way more space-efficient. As an example, Bibata-XCursor is 44.1MB, while it's 6.6MB in hyprcursor.
+
+## Tools
+
+### hyprcursor-util
+
+Utility for creating hyprcursor themes. See its readme in `hyprcursor-util/`
+
+### libhyprcursor
+
+The library to use for implementing hyprcursors in your compositor or app.

+
+## TODO
+
+Library:
+ - [ ] Support animated cursors
+ - [ ] Support SVG cursors
+
+Util:

+ - [ ] Support decompiling animated cursors
