 **Versioned plugin manifests**:
 - **GitHub Copilot** — `.github\plugin\plugin.json` is the Copilot marketplace manifest and points at the repo root.
-- **Claude Code** — `.claude-plugin\plugin.json` defines the Claude Code plugin package; `.claude-plugin\marketplace.json` defines Claude Code marketplace publishing metadata.
+- **Claude Code** — `.claude-plugin\plugin.json` defines the Claude Code plugin package; `.claude-plugin\marketplace.json` is the Claude Code marketplace index, generated by `apm pack` from the `marketplace:` block in `apm.yml`.
+- **APM** — `apm.yml` is the Agent Package Manager manifest at the repo root. It declares the package identity, version, targets, MCP dependencies, and marketplace metadata. The `marketplace:` block in `apm.yml` is the source of truth for the APM marketplace index; `apm pack` generates `.claude-plugin/marketplace.json` from it. APM follows the existing `plugin.json` pointers to locate skills and MCP config — no separate `.apm/` directory is needed.
 
 ## Sync rules
 
 - Event support is duplicated by design between the CLI and skill docs. When adding, removing, or renaming events, update `cli\src\config.ts`, the supported/default event guidance in `skills\microsoft-build\SKILL.md`, and affected tests/docs together.
 - Treat `skills\microsoft-build\SKILL.md` as the product contract for event-session behavior. For Build, Ignite, or event-session work: default "Build" to `build-2026`, get session metadata from the live catalog through `msevents` or the endpoint, get SDK/API facts from Microsoft Learn MCP, and never invent session IDs, speakers, schedules, or links.
-- Versioning gate: any meaningful `skills\microsoft-build\SKILL.md` change (agent behavior, commands/examples agents may follow, supported/default events, CLI/MCP/catalog usage, or user-facing workflow guidance) must bump both versioned plugin manifests to the same value; patch bumps are fine for guidance-only changes.
-- PR review gate: GitHub Copilot/code reviewers should flag meaningful `SKILL.md` changes without synced plugin version bumps, and any plugin version drift. Typo/format-only skill edits may skip the bump only when the PR explicitly says so.
+- Versioning gate: any meaningful `skills\microsoft-build\SKILL.md` change (agent behavior, commands/examples agents may follow, supported/default events, CLI/MCP/catalog usage, or user-facing workflow guidance) must bump all versioned plugin manifests (`.github\plugin\plugin.json`, `.claude-plugin\plugin.json`, and `apm.yml` including its `marketplace.packages[].version`) to the same value; patch bumps are fine for guidance-only changes.
+- PR review gate: GitHub Copilot/code reviewers should flag meaningful `SKILL.md` changes without synced plugin version bumps, and any plugin version drift across the three manifests. Typo/format-only skill edits may skip the bump only when the PR explicitly says so.
 - Keep README install/client guidance aligned with plugin manifest, skill, MCP, or CLI behavior changes.

+## Install with APM
+
+[APM (Agent Package Manager)](https://github.com/microsoft/apm) is to AI agent skills what npm is to JavaScript packages — it lets you install, version, and share reusable agent instructions, skills, and MCP configurations across projects with a single command.
+
+### Global install (all projects)
+
+```bash
+# Both Claude Code and GitHub Copilot
+apm install -g microsoft/Build-CLI#v1.0.5 --target claude,copilot
+
+# Claude Code only
+apm install -g microsoft/Build-CLI#v1.0.5 --target claude
+
+# GitHub Copilot only
+apm install -g microsoft/Build-CLI#v1.0.5 --target copilot
+```

+### Verify, update, and uninstall
+
+```bash

+apm outdated -g               # Check for updates
