+# Contributing to SFLabs Knowledge Base
+
+Welcome! This is the shared knowledge base for all SFLabs projects.
+
+## How to Contribute
+
+### Adding New Memories
+
+1. **Choose the right type:**
+   - `memories/user/` — About people, roles, expertise
+   - `memories/feedback/` — LLM guidance, preferences
+   - `memories/project/` — Project context, decisions
+   - `memories/reference/` — External resources, tools
+
+2. **Use templates:**
+   ```bash
+   # In Obsidian: Ctrl+P → Templates → Choose type
+   # Or copy from templates/ folder
+   ```
+
+3. **Follow the structure:**
+   ```yaml
+   ---
+   name: descriptive-name
+   description: One-line summary
+   type: user|feedback|project|reference
+   created: 2026-05-15
+   ---
+   ```
+
+4. **Add links:** Connect related memories with `[[wikilinks]]`
+
+### Commit Messages
+
+Use descriptive commit messages:
+- ✅ "Add feedback: no-summary-responses"
+- ✅ "Update project: tier2-setup - add timeline"
+- ❌ "fix stuff"
+
+### Syncing
+
+**Before starting work:**
+```bash
+sflabs-kdb pull
+```
+
+**After completing work:**
+```bash
+git add .
+git commit -m "Your descriptive message"
+sflabs-kdb push
+```
+
+## Best Practices
+
+1. **Be specific** — Clear rules, concrete examples
+2. **Include why** — Context helps with edge cases
+3. **Link generously** — Build the knowledge graph
+4. **Keep it current** — Archive outdated memories
+5. **One idea per file** — Easier to link and find
