Teknium 37524a574e docs: add PR review guides, rework quickstart, slim down installation 
Adds two complementary GitHub PR review guides from contest submissions:
- Cron-based PR review agent (from PR #5836 by @dieutx) — polls on a
  schedule, no server needed, teaches skills + memory authoring
- Webhook-based PR review (from PR #6503 by @gaijinkush) — real-time via
  GitHub webhooks, documents previously undocumented webhook feature
Both guides are cross-linked so users can pick the approach that fits.

Reworks quickstart.md by integrating the best content from PR #5744
by @aidil2105:
- Opinionated decision table ('The fastest path')
- Common failure modes table with causes and fixes
- Recovery toolkit sequence
- Session lifecycle verification step
- Better first-chat guidance with example prompts

Slims down installation.md:
- Removes 10-step manual/dev install section (already covered in
  developer-guide/contributing.md)
- Links to Contributing guide for dev setup
- Keeps focused on the automated installer + prerequisites + troubleshooting

2 Installation Install Hermes Agent on Linux, macOS, WSL2, or Android via Termux

Installation

Get Hermes Agent up and running in under two minutes with the one-line installer.

Quick Install

Linux / macOS / WSL2

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:

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.

:::warning Windows Native Windows is not supported. Please install WSL2 and run Hermes Agent from there. The install command above works inside WSL2. :::

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.

After Installation

Reload your shell and start chatting:

source ~/.bashrc   # or: source ~/.zshrc
hermes             # Start chatting!

To reconfigure individual settings later, use the dedicated commands:

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 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 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.
