**To set up Lum1104/Understand-Anything locally, clone the repository, install dependencies using pnpm, build the core TypeScript package and React dashboard, and launch the development server to visualize interactive knowledge graphs.**

Understand-Anything is a multi-agent, tree-sitter and LLM hybrid tool that transforms codebases into interactive knowledge graphs. Whether you are analyzing a new project or integrating the tool into your development workflow, this guide walks you through the exact steps to configure and run Lum1104/Understand-Anything on your local machine using the official monorepo structure.

## Prerequisites

Before you begin, ensure your environment meets the following requirements:

- **Node.js ≥ 22** (tested on v24) – Required by the TypeScript build scripts.
- **pnpm ≥ 10** – The monorepo workspace manager, pinned in the root [`package.json`](https://github.com/Lum1104/Understand-Anything/blob/main/package.json).
- **git** – To clone the repository.
- **git-lfs** (optional) – Recommended for tracking large knowledge-graph JSON files exceeding 10 MB.

## Clone the Repository

Start by cloning the repository and navigating into the project directory:

```bash
git clone https://github.com/Lum1104/Understand-Anything.git
cd Understand-Anything

```

The repository is organized as a pnpm workspace, with all packages located under the `understand-anything-plugin/` directory.

## Install Dependencies

Run the following command to install all workspace dependencies:

```bash
pnpm install

```

This command reads the workspace manifest ([`pnpm-workspace.yaml`](https://github.com/Lum1104/Understand-Anything/blob/main/pnpm-workspace.yaml)) and installs:

- **Core dependencies** – Tree-sitter parsers and `web-tree-sitter` as defined in [`understand-anything-plugin/packages/core/package.json`](https://github.com/Lum1104/Understand-Anything/blob/main/understand-anything-plugin/packages/core/package.json).
- **Dashboard dependencies** – React, Zustand, and Tailwind v4 as defined in [`understand-anything-plugin/packages/dashboard/package.json`](https://github.com/Lum1104/Understand-Anything/blob/main/understand-anything-plugin/packages/dashboard/package.json).

## Build the Core Package

Compile the core TypeScript library using the workspace filter command:

```bash
pnpm --filter @understand-anything/core build

```

This executes the TypeScript compiler (`tsc`) and outputs the compiled files to the `dist/` directory. The export map in the core [`package.json`](https://github.com/Lum1104/Understand-Anything/blob/main/package.json) ensures the dashboard only imports browser-safe sub-paths (`./search`, `./types`, `./schema`).

## Build the Dashboard Package

Build the React-based visualization interface:

```bash
pnpm --filter @understand-anything/dashboard build

```

The dashboard build process generates a static bundle in `dist/`, ready for deployment or local development.

## Run Tests (Optional)

Verify the installation by running the test suite:

- **Core tests only**:

  ```bash
  pnpm --filter @understand-anything/core test
  ```

- **Full test suite** (including skill plugins):

  ```bash
  pnpm test
  ```

Tests utilize **Vitest** and cover the core engine and skill definitions. Example fixtures are located in `tests/skill/understand/`, including files like [`scan-result-large-community.json`](https://github.com/Lum1104/Understand-Anything/blob/main/scan-result-large-community.json).

## Start the Development Server

Launch the hot-reload development server to access the dashboard:

```bash
pnpm dev:dashboard

```

The server typically starts at `http://localhost:3000` (check console output for the exact port). The dashboard reads the generated knowledge graph from [`.understand-anything/knowledge-graph.json`](https://github.com/Lum1104/Understand-Anything/blob/main/.understand-anything/knowledge-graph.json) via the [`/file-content.json`](https://github.com/Lum1104/Understand-Anything/blob/main//file-content.json) endpoint.

## Run the Analyzer

To analyze a target project and generate the knowledge graph, run the CLI from the repository root:

```bash
node ./understand-anything-plugin/dist/cli.js understand

```

The analyzer creates [`.understand-anything/knowledge-graph.json`](https://github.com/Lum1104/Understand-Anything/blob/main/.understand-anything/knowledge-graph.json) in your target directory. Subsequent runs are incremental, scanning only files that have changed since the last execution.

## One-Line Installer (Optional)

For a platform-native CLI experience similar to Claude Code or other integrations, use the automated installer:

**macOS / Linux:**

```bash
curl -fsSL https://raw.githubusercontent.com/Lum1104/Understand-Anything/main/install.sh | bash

```

**Windows PowerShell:**

```powershell
iwr -useb https://raw.githubusercontent.com/Lum1104/Understand-Anything/main/install.sh | iex

```

The installer script ([`install.sh`](https://github.com/Lum1104/Understand-Anything/blob/main/install.sh) or `install.ps1`) clones the repository to `~/.understand-anything/repo` and creates the necessary symlinks for your specific platform.

## Summary

Setting up Lum1104/Understand-Anything locally involves several key steps:

- Install **Node.js ≥ 22** and **pnpm ≥ 10** before starting.
- Build both the **core** (`@understand-anything/core`) and **dashboard** (`@understand-anything/dashboard`) packages using `pnpm --filter`.
- Use `pnpm dev:dashboard` to start the development server at `localhost:3000`.
- Generate knowledge graphs using the CLI entry point or the one-line installer.
- Store generated graphs in [`.understand-anything/knowledge-graph.json`](https://github.com/Lum1104/Understand-Anything/blob/main/.understand-anything/knowledge-graph.json), optionally tracked with git-lfs for large files.

## Frequently Asked Questions

### What are the minimum system requirements to run Understand-Anything locally?

You need **Node.js version 22 or higher** and **pnpm version 10 or higher**. The TypeScript compiler and React dashboard build processes rely on modern Node features, while pnpm manages the monorepo workspace dependencies defined across [`understand-anything-plugin/packages/core/package.json`](https://github.com/Lum1104/Understand-Anything/blob/main/understand-anything-plugin/packages/core/package.json) and [`understand-anything-plugin/packages/dashboard/package.json`](https://github.com/Lum1104/Understand-Anything/blob/main/understand-anything-plugin/packages/dashboard/package.json).

### How do I update the knowledge graph after modifying my code?

Simply re-run the analyzer command. The system performs incremental updates, scanning only changed files to regenerate [`.understand-anything/knowledge-graph.json`](https://github.com/Lum1104/Understand-Anything/blob/main/.understand-anything/knowledge-graph.json). For automatic updates on every commit, enable the post-commit hook using `/understand --auto-update` after installing the CLI via [`install.sh`](https://github.com/Lum1104/Understand-Anything/blob/main/install.sh).

### Can I use npm or yarn instead of pnpm?

No, the repository is configured specifically as a **pnpm workspace** using [`pnpm-workspace.yaml`](https://github.com/Lum1104/Understand-Anything/blob/main/pnpm-workspace.yaml). The dependency hoisting and workspace linking are optimized for pnpm, and the build scripts in the root [`package.json`](https://github.com/Lum1104/Understand-Anything/blob/main/package.json) assume pnpm's filtering syntax (`--filter`).

### Where is the generated knowledge graph stored?

By default, the analyzer outputs to [`.understand-anything/knowledge-graph.json`](https://github.com/Lum1104/Understand-Anything/blob/main/.understand-anything/knowledge-graph.json). The dashboard reads from this location via the [`/file-content.json`](https://github.com/Lum1104/Understand-Anything/blob/main//file-content.json) endpoint. For graphs larger than 10 MB, the documentation recommends using **git-lfs** to track this file while excluding `intermediate/` directories and [`diff-overlay.json`](https://github.com/Lum1104/Understand-Anything/blob/main/diff-overlay.json) from version control.
