+# Behavioral Modes
+
+Ready-to-use behavioral mode files for Claude Code. Copy to `~/.claude/` and reference in your `CLAUDE.md`.
+
+## Available Modes
+
+| Mode | File | Purpose |
+|------|------|---------|
+| **Learning** | [MODE_Learning.md](./MODE_Learning.md) | Just-in-time explanations when techniques are first used |
+
+## Installation
+
+### 1. Copy the mode file
+
+```bash
+cp MODE_Learning.md ~/.claude/
+```
+
+### 2. Reference in your CLAUDE.md
+
+Add to `~/.claude/CLAUDE.md`:
+
+```markdown
+# Behavioral Modes
+@MODE_Learning.md
+```
+
+### 3. Add flags (optional)
+
+Add to `~/.claude/FLAGS.md` for flag-based activation:
+
+```markdown
+**--learn**
+- Trigger: User requests learning mode, "why/how" questions
+- Behavior: Enable just-in-time explanations with first-occurrence tracking
+
+**--no-learn**
+- Trigger: User wants pure execution without educational offers
+- Behavior: Suppress all learning mode offers
+```
+
+## Usage
+
+```bash
+# Activate for entire session
+claude --learn
+
+# Focus on specific domain
+claude --learn focus:git
+claude --learn focus:architecture
+
+# Batch explanations at task end
+claude --learn batch
+```
+
+## More Modes: SuperClaude Framework
+
+This guide includes only **Learning Mode**. For a complete behavioral framework with additional modes, check out [SuperClaude](https://github.com/SuperClaude-Org/SuperClaude_Framework):
+
+| Mode | Purpose |
+|------|---------|
+| **Orchestration** | Smart tool selection, parallel execution optimization |
+| **Task Management** | Hierarchical task tracking with persistent memory |
+| **Token Efficiency** | Symbol-enhanced compression (30-50% token reduction) |
+| **Learning** | Just-in-time skill development (included here) |
+
+SuperClaude also includes:
+- `FLAGS.md` — Behavioral flags (`--think`, `--ultrathink`, `--delegate`, etc.)
+- `PRINCIPLES.md` — Engineering principles (SOLID, DRY, evidence-based)
+- `RULES.md` — Actionable rules with priority system
+- MCP server documentation (Context7, Sequential, Serena)
