Small app. Open notebook.

Paper is a free, open-source texture overlay for Apple Silicon Macs. These guides cover the code, recipes, testing and releases. If you just want to use the app, start with the user guide.

• Build Paper — requirements and contribution checks.
• Understand the architecture — policy, state and native adapters.
• Make a recipe — Deckle-compatible imports and library backups.
• Test a change — automated evidence and real-device limits.
• Package a release — signing, updates and validation.
• Meet the upstream projects — starting with Deckle.

Source and release

The downloadable app is Paper 1.0.3. These docs follow source commit 8713988, including documentation changes after that release. A source change is not automatically a shipped app feature. See the source map and changelog.
