 ## Installation
 
-### Quick Install (Recommended)
+### Homebrew (Recommended)
+
+```bash
+brew install llbbl/tap/upkeep
+```

+### Install Script
 
 ```bash
 curl -fsSL https://raw.githubusercontent.com/llbbl/upkeep/main/scripts/install.sh | bash
 ```
 
-This installs:
-- The `upkeep` CLI binary to `~/.local/bin/` (or `~/.upkeep/bin/` if that doesn't exist)
-- Claude Code skills to `~/.claude/skills/` for AI-powered workflows
+This installs the `upkeep` CLI binary to `~/.local/bin/` (or `~/.upkeep/bin/` if that doesn't exist). It no longer installs the skills — those come from the plugin marketplace (see [Claude Code Skills](#claude-code-skills)).
 
 To install a specific version:

+UPKEEP_VERSION=v0.2.0 curl -fsSL https://raw.githubusercontent.com/llbbl/upkeep/main/scripts/install.sh | bash

 ## Claude Code Skills
 
-upkeep includes skills for Claude Code that provide AI-powered maintenance workflows. Each skill has access to the upkeep binary:
+upkeep ships its Claude Code skills as a plugin distributed through its own marketplace. Install them with:
+
+```text
+/plugin marketplace add llbbl/upkeep
+/plugin install upkeep@llbbl-upkeep
+```
 
-### `/upkeep-deps`
+This installs all three skills, namespaced under the `upkeep` plugin. The skills shell out to the `upkeep` CLI, so make sure the binary is installed and on your `PATH` first (see [Installation](#installation)).
+
+### `/upkeep:deps`
 
 Upgrade dependencies with intelligent risk assessment:
 - Prioritizes Dependabot PRs and security fixes
 - Assesses risk before each upgrade
 - Runs tests and rolls back on failure
 
-### `/upkeep-audit`
+### `/upkeep:audit`
 
 Security audit with fix recommendations:
 - Explains each vulnerability
 - Shows dependency paths
 - Guides through safe fixes
 
-### `/upkeep-quality`
+### `/upkeep:quality`

 - Explains quality metrics
