# Installation
Get Hermes Agent up and running in under two minutes with the one-line installer.
## Quick Install
### Desktop App (macOS + Windows)
Prefer a native installer? Use the desktop release channel that matches your risk tolerance:
- **Stable (recommended):** [GitHub Releases](https://github.com/NousResearch/hermes-agent/releases/latest)
- **Nightly (rolling prerelease):** [desktop-nightly](https://github.com/NousResearch/hermes-agent/releases/tag/desktop-nightly)
Stable desktop builds ship signed/notarized macOS artifacts and Windows installers with checksum files.
### Linux / macOS / WSL2
```bash
curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash
```
### Android / Termux
Hermes now ships a Termux-aware installer path too:
```bash
curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash
```
The installer detects Termux automatically and switches to a tested Android flow:
- uses Termux `pkg` for system dependencies (`git`, `python`, `nodejs`, `ripgrep`, `ffmpeg`, build tools)
- creates the virtualenv with `python -m venv`
- exports `ANDROID_API_LEVEL` automatically for Android wheel builds
- installs a curated `.[termux]` extra with `pip`
- skips the untested browser / WhatsApp bootstrap by default
If you want the fully explicit path, follow the dedicated [Termux guide](./termux.md).
:::warning Windows
Native Windows for the **CLI installer path** is still not supported. Please install [WSL2](https://learn.microsoft.com/en-us/windows/wsl/install) and run Hermes Agent from there if you want the CLI flow.
For native Windows, use the desktop installers from [GitHub Releases](https://github.com/NousResearch/hermes-agent/releases/latest).

### What the Installer Does
The installer handles everything automatically — all dependencies (Python, Node.js, ripgrep, ffmpeg), the repo clone, virtual environment, global `hermes` command setup, and LLM provider configuration. By the end, you're ready to chat.
#### Install Layout
Where the installer puts things depends on whether you're installing as a normal user or as root:
| Installer | Code lives at | `hermes` binary | Data directory |
|---|---|---|---|
| Per-user (normal) | `~/.hermes/hermes-agent/` | `~/.local/bin/hermes` (symlink) | `~/.hermes/` |
| Root-mode (`sudo curl … \| sudo bash`) | `/usr/local/lib/hermes-agent/` | `/usr/local/bin/hermes` | `/root/.hermes/` (or `$HERMES_HOME`) |
The root-mode **FHS layout** (`/usr/local/lib/…`, `/usr/local/bin/hermes`) matches where other system-wide developer tools land on Linux. It's useful for shared-machine deployments where one system install should serve every user. Per-user config (auth, skills, sessions) still lives under each user's `~/.hermes/` or explicit `HERMES_HOME`.
### After Installation
Reload your shell and start chatting:
```bash
source ~/.bashrc # or: source ~/.zshrc
hermes # Start chatting!
```
To reconfigure individual settings later, use the dedicated commands:
```bash
hermes model # Choose your LLM provider and model
hermes tools # Configure which tools are enabled
hermes gateway setup # Set up messaging platforms
hermes config set # Set individual config values
hermes setup # Or run the full setup wizard to configure everything at once
```

## Prerequisites
The only prerequisite is **Git**. The installer automatically handles everything else:
- **uv** (fast Python package manager)
- **Python 3.11** (via uv, no sudo needed)
- **Node.js v22** (for browser automation and WhatsApp bridge)
- **ripgrep** (fast file search)
- **ffmpeg** (audio format conversion for TTS)
:::info
You do **not** need to install Python, Node.js, ripgrep, or ffmpeg manually. The installer detects what's missing and installs it for you. Just make sure `git` is available (`git --version`).

:::tip Nix users
If you use Nix (on NixOS, macOS, or Linux), there's a dedicated setup path with a Nix flake, declarative NixOS module, and optional container mode. See the **[Nix & NixOS Setup](./nix-setup.md)** guide.

## Manual / Developer Installation
If you want to clone the repo and install from source — for contributing, running from a specific branch, or having full control over the virtual environment — see the [Development Setup](../developer-guide/contributing.md#development-setup) section in the Contributing guide.

## Troubleshooting
| Problem | Solution |
|---------|----------|
| `hermes: command not found` | Reload your shell (`source ~/.bashrc`) or check PATH |
| `API key not set` | Run `hermes model` to configure your provider, or `hermes config set OPENROUTER_API_KEY your_key` |
| Missing config after update | Run `hermes config check` then `hermes config migrate` |
For more diagnostics, run `hermes doctor` — it will tell you exactly what's missing and how to fix it.
