+  A long-term memory layer for VS Code Copilot.<br/>
+  Learns from your conversations. Stays local. Gets smarter over time.
+</p>
+
+---
+
+## What It Does
+
+HackLM Memory gives Copilot a persistent memory across sessions. It stores decisions, preferences, quirks, and security rules in plain Markdown files inside your project.
+
+- **Learns passively** — picks up preferences and rules from natural conversation
+- **Never stores duplicates** — deduplication runs on every write
+- **Self-cleaning** — periodic cleanup merges similar entries and prunes stale ones
+- **Workspace-scoped** — each project has its own `.memory/` folder
+- **Fully local** — no cloud sync, no telemetry
+
+---
+
+## Getting Started
+
+1. Install the extension
+2. Open a workspace — memory files are created automatically in `.memory/`
+3. Start chatting with Copilot — it will read and write memories automatically
+4. Click **Memory** in the status bar to open the control panel
+
+---
+
+## Memory Categories
+
+| Category | What It Stores |
+|----------|----------------|
+| **Instruction** | How Copilot should behave in this project |
+| **Quirk** | Non-obvious project-specific knowledge |
+| **Preference** | Style, tone, and design choices |
+| **Decision** | Architectural commitments |
+| **Security** | Rules that must never be broken |
+
+---
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `HackLM Memory: Open Control Panel` | Browse all actions in one place |
+| `HackLM Memory: List Memories` | View all stored entries |
+| `HackLM Memory: Delete Memory` | Remove a specific entry |
+| `HackLM Memory: Run Cleanup` | Merge duplicates and prune stale entries |
+| `HackLM Memory: Review Session` | Find decisions not yet captured |
+| `HackLM Memory: Open Memory Folder` | Browse `.memory/` files directly |
+
+---
+
+## Settings
+
+| Setting | Default | Description |

+| `hacklm-memory.categoryLimit.*` | `20` | Max entries per category |
+
+---
+
+## Privacy
+
+All memory is stored locally in your workspace `.memory/` folder. Nothing leaves your machine.  
+Add `.memory/` to `.gitignore` if any contents are sensitive.
