+# AirPlan-ParaV2 Deployment Bundle
+
+This bundle packages the Air workflow suite plus the standalone AirContext component for deployment on another computer.
+
+## Included components
+
+### Air workflow suite
+- plugins: airarc, aireng, airdo, airdbg, airxdb, airndb, airsdb
+- `lib/air_runtime`
+- `.agents/skills/*`
+- `.agents/plugins/marketplace.json`
+- `install_to_home.ps1`
+- `init_project_airplan.ps1`
+
+### AirContext
+- `AirContextServer/`
+- `install_aircontext_local.ps1`
+- `aircontext-settings-snippet.json`
+
+## Quick install
+
+### Install the Air workflow suite
+Run in PowerShell from this extracted folder:
+
+```powershell
+.\install_to_home.ps1
+```
+
+### Stage AirContext on the target machine
+Run:
+
+```powershell
+.\install_aircontext_local.ps1
+```
+
+This copies `AirContextServer` to `%USERPROFILE%\AirContextServer` and prints the settings snippet path to enable the plugin in Claude Code.
+
+### Install everything in one step
+Run:
+
+```powershell
+.\install_all.ps1
+```
+
+## Notes
+
+- `aireng` is packaged from the current updated implementation and no longer keeps `air-engine` as a public entrypoint.
+- AirContext is shipped as a separate component because it is not part of the `plugins/` development tree.
+- The bundled `aircontext-settings-snippet.json` shows the Claude settings shape needed to enable the local AirContext marketplace.
