 ## Features
 
-- Draw keymap representations consisting of multiple layers, hold-tap keys and combos
+- **Draw keymap representations** consisting of multiple layers, hold-tap keys and combos
   - Uses a human-editable YAML format for specifying the keymap
   - Non-adjacent or 3+ key combos can be visualized by specifying its positioning relative to the keys, with automatically drawn dendrons to keys
   - Alternatively, output a separate diagram per combo if you have tricky key position combinations
-- Bootstrap the YAML representation by automatically parsing QMK or ZMK keymap files
-- Arbitrary physical keyboard layouts (with rotated keys!) supported, along with parametrized ortho layouts
-- Both parsing and drawing are customizable with a config file, see ["Customization" section](#customization)
-- Custom glyph support: render custom SVG icons and not just unicode text
