-# Update persistent memory
-opencode run "use core_memory_update to set my goal"

-# Add important items to working memory

-- Track memory pressure and warn when approaching compaction

-- Preserve important context during compaction

 # Installation Guide
 
-## Prerequisites
+## Quick Install
 
-- **OpenCode** 1.0.0 or higher
+Add to your `~/.config/opencode/opencode.json`:
-- **Node.js** 18+ (for development only)
-
-## Quick Install (For Users)
-
-### Option 1: Install from npm (Recommended)
-
-```bash
-npm install opencode-working-memory
-```
-
-Then add to your `.opencode/package.json`:
 
 ```json
 {
-  "plugins": [
+  "plugin": ["opencode-working-memory"]
-    "opencode-working-memory"
-  ]
 }
 ```
 
-### Option 2: Install from GitHub
+Restart OpenCode. The plugin is downloaded and installed automatically — no `npm install` needed.
 
-Add to your `.opencode/package.json`:
+> **Note**: The correct key is `plugin` (singular), not `plugins`.

-Then run:
+1. Edit `~/.config/opencode/opencode.json`
-
+2. Add `"opencode-working-memory"` to the `plugin` array
-```bash
+3. Verify the config file was saved correctly
-cd .opencode
-npm install
-```
-
-### Option 3: Local Development Install
-
-Clone the repository:
-
-```bash
-git clone https://github.com/sdwolf4103/opencode-working-memory.git
-cd opencode-working-memory
-npm install
-```
-
-Link to your OpenCode project:
-
-```bash

 ## Verification
 
-After installation, start an OpenCode session and run:
+After restarting OpenCode, ask your agent:
 
 ```
-core_memory_update goal "Test installation"
