+# Contributing to Illuscape
+
+Thank you for helping make Inkscape more accessible to Illustrator migrants.
+
+## How to add a keyboard shortcut
+
+1. Open `config/keys/illustrator-cc.xml` and/or `config/keys/illustrator-cs6.xml`
+2. Add a `<bind>` element:
+   ```xml
+   <bind key="KEY" action="INKSCAPE_ACTION" modifiers="Primary,Shift" />
+   ```
+   Valid modifiers: `Primary` (Ctrl/Cmd), `Shift`, `Alt`. Omit `modifiers=""` for bare keys.
+3. Find Inkscape action names via `inkscape --action-list` on your system
+4. Update the shortcut table in `README.md`
+5. Update the shortcut comparison table in the spec if the shortcut differs between CC and CS6
+
+## How to add a color palette
+
+1. Create `config/palettes/YourPalette.gpl` following GPL format:
+   ```
+   GIMP Palette
+   Name: Your Palette Name
+   Columns: 8
+   #
+   255   0   0  Red
+   ...
+   ```
+2. Add the filename to `uninstall.sh`'s `remove_files()` function so it gets cleaned up
+3. The palette will be installed automatically by `install.sh` (it copies all `*.gpl` files)
+
+## How to add a document template
+
+1. Create an SVG at `config/templates/YourTemplate.svg`
+2. Include a `sodipodi:namedview` element with appropriate canvas settings
+3. Add the filename to `uninstall.sh`'s `remove_files()` function
+4. The template will be installed automatically by `install.sh` (copies all `*.svg` files)
+
+## How to add a preference
+
+Preferences live in `config/preferences-patch.xml`. The XML merge algorithm (in
+`scripts/merge_prefs.py`) does an upsert: it walks the patch tree, matches nodes
+by their `id` attribute, and sets only the attributes present in the patch. It
+never deletes nodes or attributes.
+
+To add a new preference:
+1. Find the relevant node in Inkscape's `preferences.xml` on a running install
+2. Add the node/attribute to `config/preferences-patch.xml` with the correct `id` values
+3. Write a test in `tests/test_merge_prefs.py` that verifies the attribute is set
+4. Run `conda run -n cf python3 -m pytest tests/test_merge_prefs.py -v` to verify
+
+## Running tests
+
+```bash
+# Python unit tests (merge algorithm)
+conda run -n cf python3 -m pytest tests/test_merge_prefs.py -v
+
+# Integration tests (requires bats-core)
+bats tests/test_install.bats
+
+# Validate all config files
+conda run -n cf python3 -c "
+from xml.etree import ElementTree as ET
+from pathlib import Path
+for f in [*Path('config/keys').glob('*.xml'), *Path('config/templates').glob('*.svg'),
+          *Path('config/symbols').glob('*.svg'), Path('config/preferences-patch.xml')]:
+    ET.parse(f)
+    print(f'OK {f}')
+"

+| Feature | Detail |
+|---------|--------|
+| Keyboard shortcuts | Adobe Illustrator CC or CS6 presets — your choice at install |
+| Scroll/zoom | Mouse wheel pans (not zooms); Ctrl+wheel zooms — matching Illustrator |
+| Canvas | White background, cyan guides, rubber-band selection (touching, not enclosed) |
+| Node handles | Square handles, rotation handles hidden until needed |
+| Palettes | Illustrator Defaults, Grays, and Earth Tones swatches |
+| Templates | Letter, A4, Web 1920x1080, Web 1280x720, Print CMYK Letter, Print CMYK A4 |
+| Symbols | Common symbol library (arrows, checkmark, star, cross) |
+| Recent files | 20 (matching Illustrator; Inkscape default is 4) |
+| Single-window mode | On by default |
