+# MVP Plan: Doodle Addon for Plone
+
+This document outlines the atomic steps for implementing a minimal Doodle-like addon for Plone, focusing on folderish and date content types, permissions, and a doodle-style view.
+
+---
+
+## Atomic Commit Steps
+
+1. **Add schema interface for `experimental.doodle.folder`**
+   - File: `src/experimental/doodle/interfaces.py`
+2. **Implement `experimental.doodle.folder` content type**
+   - File: `src/experimental/doodle/content/folder.py`
+3. **Register `experimental.doodle.folder` in ZCML**
+   - File: `src/experimental/doodle/configure.zcml`
+4. **Add type info XML for folder**
+   - File: `src/experimental/doodle/profiles/default/types/experimental.doodle.folder.xml`
+5. **Add custom permissions for folder**
+   - File: `src/experimental/doodle/permissions.zcml`
+6. **Add schema interface for `experimental.doodle.date`**
+   - File: `src/experimental/doodle/interfaces.py`
+7. **Implement `experimental.doodle.date` content type**
+   - File: `src/experimental/doodle/content/date.py`
+8. **Register `experimental.doodle.date` in ZCML**
+   - File: `src/experimental/doodle/configure.zcml`
+9. **Add type info XML for date**
+   - File: `src/experimental/doodle/profiles/default/types/experimental.doodle.date.xml`
+10. **Add custom permissions for date**
+    - File: `src/experimental/doodle/permissions.zcml`
+11. **Implement user selection logic (`participants` field) in date type**
+12. **Implement doodle-style browser view**
+    - File: `src/experimental/doodle/browser/doodleview.py`
+13. **Add tests for type creation and permissions**
+14. **Update documentation**
+    - Files: `README.md`, `docs/concepts/plan.md`
+

+
+## Key Decisions
+- Two types: `experimental.doodle.folder` (folderish), `experimental.doodle.date` (date, non-folderish)
+- `participants` field for user selection
+- Custom permissions for each type
+- Doodle-style view for folder
+
+---
+
+## Verification
+- Addon installs, both types available
+- Permission separation works
+- Dates can be added, users can select dates
+- Doodle view displays sorted dates and user selections
+- Tests and lint pass after each step
