+# LexAI for VS Code — Install & Deploy
+
+## Installable package (already built)
+
+| Item | Value |
+| --- | --- |
+| File | `packages/vscode/lexai-vscode-1.0.0.vsix` |
+| Extension id | `JuanKibin.lexai-vscode` |
+| Rebuild | from repo root: `npm run vscode:package` |
+
+---
+
+## A. Install on your machine (sideload)
+
+### VS Code
+
+1. Rebuild if needed: `npm run vscode:package` (repo root).
+2. Open VS Code → **Extensions** (`Ctrl+Shift+X`).
+3. `…` menu (top of Extensions) → **Install from VSIX…**
+4. Pick `packages/vscode/lexai-vscode-1.0.0.vsix`.
+5. Reload when prompted.
+6. **LexAI: Open Settings** → set provider + API key.
+
+### Cursor
+
+Same flow: **Extensions → … → Install from VSIX…** → select the `.vsix`.
+
+### CLI (optional)
+
+```powershell
+# VS Code
+code --install-extension packages\vscode\lexai-vscode-1.0.0.vsix
+
+# Cursor (if `cursor` CLI is on PATH)
+cursor --install-extension packages\vscode\lexai-vscode-1.0.0.vsix
+```
+
+### Share with teammates
+
+Send them the `.vsix` file (email, Drive, Slack, release artifact). They use **Install from VSIX…** — no Marketplace account required.
+
+---
+
+## B. Publish to the Visual Studio Marketplace (public)
+
+So anyone can install via search: “LexAI”.
+
+### 1. Create a publisher
+
+1. Go to [https://marketplace.visualstudio.com/manage](https://marketplace.visualstudio.com/manage)  
+   (sign in with a Microsoft account).
+2. Create a **publisher** whose id matches `package.json` → `"publisher": "JuanKibin"`.  
+   - The Marketplace publisher id must be exactly `JuanKibin` (case-sensitive).
+3. Under the publisher, create a **Personal Access Token** (Azure DevOps):
+   - Organization: all accessible / the one tied to Marketplace
+   - Scopes: **Marketplace → Manage**
+   - Copy the token once.
+
+### 2. Login & publish
+
+```powershell
+cd packages\vscode
+npx vsce login JuanKibin
+# paste the PAT when prompted
+
+npm run package
+npx vsce publish
+# or: npx vsce publish patch   # bumps 1.0.0 → 1.0.1 and publishes
+```
+
+`"private"` is `false` so Marketplace publish is allowed.
+
+### 3. After publish
+
+- Listing: `https://marketplace.visualstudio.com/items?itemName=JuanKibin.lexai-vscode`
+- Users install from Extensions search, or:
+
+```powershell
+code --install-extension JuanKibin.lexai-vscode
+```
+
+### 4. Version bumps
+
+Edit `version` in `packages/vscode/package.json` (or use `vsce publish patch|minor|major`), rebuild/package, publish again. Keep README/DEPLOY in sync with the version you ship.
+
+---
+
+## C. Optional: Open VSX (Cursor / VSCodium catalogs)
+
+Some editors prefer [Open VSX](https://open-vsx.org/) instead of (or in addition to) the Microsoft Marketplace.
+
+1. Create an account at [https://open-vsx.org](https://open-vsx.org).
+2. Create an access token in your profile.
+3. Publish:
+
+```powershell
+cd packages\vscode
+npm run package
+npx ovsx publish lexai-vscode-1.0.0.vsix -p <OPEN_VSX_TOKEN>
+```
+
+(`npx ovsx` uses the `ovsx` CLI; install once with `npm i -D ovsx` if you prefer.)
+
+---
+
+## D. Checklist before a public release
+
+- [ ] Manual smoke: Code Assist + one writing action + API key in Secret Storage  
+- [ ] `npm run vscode:typecheck` and `npm run vscode:package` succeed  
+- [ ] Publisher id is yours and matches `package.json`  
+- [ ] `"private": false` for Marketplace  
+- [ ] Add `"repository"` URL in `package.json` when the repo is public (clears the vsce warning)  
+- [ ] Confirm LICENSE is correct for your org
