Requirements

• macOS 27 or later
• A self-hosted WordPress site running WordPress 7.0 or later, served over HTTPS
• WordPress.com is not supported

Build

Building needs Swift 6.3.1 and a full Xcode install. build.sh compiles the asset catalog with actool, which the Command Line Tools alone do not provide.

./build.sh && open Quill.app

The test suite needs node and jsdom installed in Scripts/, not in the project root.

./test.sh

Architecture

Start with CLAUDE.md. It maps Sources/QuillKit, records the key design decisions, and indexes the per-directory gotcha files. Longer notes live in docs/.
