-# Installing Understand-Anything for Antigravity
-
-## Prerequisites
-
-- Git
-
-## Installation
-
-1. **Clone the repository:**
-   ```bash
-   git clone https://github.com/Lum1104/Understand-Anything.git ~/.antigravity/understand-anything
-   ```
-
-2. **Create the skills symlinks:**
-   ```bash
-   mkdir -p ~/.gemini/antigravity/skills
-   ln -s ~/.antigravity/understand-anything/understand-anything-plugin/skills ~/.gemini/antigravity/skills/understand-anything
-   # Universal plugin root symlink — lets the dashboard skill find packages/dashboard/
-   # Skip if already exists (e.g. another platform was installed first)
-   [ -e ~/.understand-anything-plugin ] || [ -L ~/.understand-anything-plugin ] || ln -s ~/.antigravity/understand-anything/understand-anything-plugin ~/.understand-anything-plugin
-   ```
-
-   **Windows (PowerShell):**
-   ```powershell
-   New-Item -ItemType Directory -Force -Path "$env:USERPROFILE\.gemini\antigravity\skills"
-   cmd /c mklink /J "$env:USERPROFILE\.gemini\antigravity\skills\understand-anything" "$env:USERPROFILE\.antigravity\understand-anything\understand-anything-plugin\skills"
-   cmd /c mklink /J "$env:USERPROFILE\.understand-anything-plugin" "$env:USERPROFILE\.antigravity\understand-anything\understand-anything-plugin"
-   ```
-
-3. **Restart the chat or IDE** so Antigravity can discover the skills.
-
-## Verify
-
-```bash
-ls -la ~/.gemini/antigravity/skills/understand-anything
-```
-
-You should see a symlink pointing to the skills directory in the cloned repo.
-
-## Usage
-
-Skills activate automatically when relevant. You can also invoke directly by saying:
-- "Run the understand skill to analyze this codebase"
-- "Use the understand-dashboard skill to view the architecture map"
-- "Use understand-chat to answer a question about the graph"
-
-## Updating
-
-```bash
-cd ~/.antigravity/understand-anything && git pull
-```
-
-Skills update instantly through the symlink.
-
-## Uninstalling
-
-```bash
-rm ~/.gemini/antigravity/skills/understand-anything
-rm ~/.understand-anything-plugin
-rm -rf ~/.antigravity/understand-anything
-```

-
-### Skills not found
-
-1. Check that the symlinks exist: `ls -la ~/.agents/skills/ | grep understand`

-### Tool mapping
-
-When skills reference Claude Code tools:

-# Installing Understand-Anything for VS Code + GitHub Copilot
-
-## Prerequisites
-
-- [VS Code](https://code.visualstudio.com/) with the [GitHub Copilot](https://marketplace.visualstudio.com/items?itemName=GitHub.copilot) extension (v1.108+)
-- Git
-
-## Option A — Auto-discovery (recommended)
-
-Clone this repo and open it in VS Code. GitHub Copilot automatically discovers the plugin via `.copilot-plugin/plugin.json` — no manual steps required.
-
-```bash
-git clone https://github.com/Lum1104/Understand-Anything.git
-code Understand-Anything
-```
-
-Skills will appear when you type `/` in GitHub Copilot Chat.
-
-## Option B — Personal skills (available across all projects)
-
-1. **Clone the repository** (to any location you prefer):
-   ```bash
-   git clone https://github.com/Lum1104/Understand-Anything.git ~/understand-anything
-   ```
-
-2. **Create a symlink for each skill** into `~/.copilot/skills/`:
-   ```bash
-   mkdir -p ~/.copilot/skills
-   SKILLS_DIR=~/understand-anything/understand-anything-plugin/skills
-   for skill in "$SKILLS_DIR"/*/; do
-     ln -sf "$skill" ~/.copilot/skills/$(basename "$skill")
-   done
-   # Universal plugin root symlink — lets the dashboard skill find packages/dashboard/
-   # Skip if already exists (e.g. another platform was installed first)
-   [ -e ~/.understand-anything-plugin ] || [ -L ~/.understand-anything-plugin ] || \
-     ln -s ~/understand-anything/understand-anything-plugin ~/.understand-anything-plugin
-   ```
-
-   **Windows (PowerShell):**
-   ```powershell
-   New-Item -ItemType Directory -Force -Path "$env:USERPROFILE\.copilot\skills"
-   $skillsDir = "$env:USERPROFILE\understand-anything\understand-anything-plugin\skills"
-   Get-ChildItem $skillsDir -Directory | ForEach-Object {
-     cmd /c mklink /J "$env:USERPROFILE\.copilot\skills\$($_.Name)" $_.FullName
-   }
-   cmd /c mklink /J "$env:USERPROFILE\.understand-anything-plugin" "$env:USERPROFILE\understand-anything\understand-anything-plugin"
-   ```
-
-3. **Reload VS Code** (`Cmd+Shift+P` → `Developer: Reload Window`) so GitHub Copilot discovers the skills.
-
-## Verify
-
-Type `/` in GitHub Copilot Chat — you should see all six skills listed:
-
-- `understand` — build the knowledge graph
-- `understand-chat` — ask questions about the codebase
-- `understand-dashboard` — open the interactive dashboard
-- `understand-diff` — analyze impact of current changes
-- `understand-explain` — deep-dive into a file or function
-- `understand-onboard` — generate an onboarding guide
-
-## Usage
-
-Skills activate automatically when relevant. You can also invoke them directly by typing `/` in Copilot Chat and selecting a skill.
-
-## Updating
-
-```bash
-cd ~/understand-anything && git pull
-```
-
-Skills update instantly through the symlinks.
-
-## Uninstalling
-
-```bash
-for skill in understand understand-chat understand-dashboard understand-diff understand-explain understand-onboard; do
-  rm -f ~/.copilot/skills/$skill
-done
-rm -f ~/.understand-anything-plugin
-rm -rf ~/understand-anything
