+# MemPalace Claude Code Plugin
+
+A Claude Code plugin that gives your AI a persistent memory system. Mine projects and conversations into a searchable palace backed by ChromaDB, with 19 MCP tools, auto-save hooks, and 5 guided skills.
+
+## Prerequisites
+
+- Python 3.9+
+
+## Installation
+
+### Claude Code Marketplace
+
+```bash
+claude plugin marketplace add milla-jovovich/mempalace
+claude plugin install --scope user mempalace
+```
+
+### Local Clone
+
+```bash
+claude plugin add /path/to/mempalace
+```
+
+## Post-Install Setup
+
+After installing the plugin, run the init command to complete setup (pip install, MCP configuration, etc.):
+
+```
+/mempalace:init
+```
+
+## Available Slash Commands
+
+| Command | Description |
+|---------|-------------|
+| `/mempalace:help` | Show available tools, skills, and architecture |
+| `/mempalace:init` | Set up MemPalace -- install, configure MCP, onboard |
+| `/mempalace:search` | Search your memories across the palace |
+| `/mempalace:mine` | Mine projects and conversations into the palace |
+| `/mempalace:status` | Show palace overview -- wings, rooms, drawer counts |
+
+## Hooks
+
+MemPalace registers two hooks that run automatically:
+
+- **Stop** -- Saves conversation context every 15 messages.
+- **PreCompact** -- Preserves important memories before context compaction.
+
+Set the `MEMPAL_DIR` environment variable to a directory path to automatically run `mempalace mine` on that directory during each save trigger.
+
+## MCP Server
+
+The plugin automatically configures a local MCP server with 19 tools for storing, searching, and managing memories. No manual MCP setup is required -- `/mempalace:init` handles everything.
+
+## Full Documentation
+
+See the main [README](../README.md) for complete documentation, architecture details, and advanced usage.
