+
+The most loved spec framework.
+
+Our philosophy:
+
+```
+→ fluid not rigid
+→ iterative not waterfall
+→ easy not complex
+→ built for brownfield not just greenfield
+→ scalable from personal projects to enterprises
+```
+
+> [!TIP]
+> **New workflow now available!** We've rebuilt OpenSpec with a new artifact-guided workflow. Run `/opsx:onboard` to get started. → [Learn more here](docs/opsx.md)

+
+## Quick Start
+
+**Requires Node.js 20.19.0 or higher.**
+
+Install OpenSpec globally:
+
+```bash
+npm install -g @fission-ai/openspec@latest
+```
+
+Then navigate to your project directory and initialize:
+
+```bash
+cd your-project
+openspec init
+```
+
+Now tell your AI: `/opsx:new <what-you-want-to-build>`
+
+> [!NOTE]
+> Not sure if your tool is supported? [View the full list](docs/supported-tools.md) – we support 20+ tools and growing.
+
+> [!NOTE]
+> Also works with pnpm, yarn, bun, and nix. [See installation options](docs/installation.md).

+
+## Why OpenSpec?
+
+AI coding assistants are powerful but unpredictable when requirements live only in chat history. OpenSpec adds a lightweight spec layer so you agree on what to build before any code is written.
+
+- **Agree before you build** — human and AI align on specs before code gets written
+- **Stay organized** — each change gets its own folder with proposal, specs, design, and tasks
+- **Work fluidly** — update any artifact anytime, no rigid phase gates
+- **Use your tools** — works with 20+ AI assistants via slash commands
+
+### How we compare
+
+**vs. [Spec Kit](https://github.com/github/spec-kit)** (GitHub) — Thorough but heavyweight. Rigid phase gates, lots of markdown, Python setup. OpenSpec is lighter and lets you iterate freely.
+
+**vs. [Kiro](https://kiro.dev)** (AWS) — Powerful but you're locked into their IDE and limited to Claude models. OpenSpec works with the tools you already use.
+
+**vs. nothing** — AI coding without specs means vague prompts and unpredictable results. OpenSpec brings predictability without the ceremony.
+
+## Updating OpenSpec
+
+1. **Upgrade the package**
+   ```bash
+   npm install -g @fission-ai/openspec@latest
+   ```
+2. **Refresh agent instructions**
+   - Run `openspec update` inside each project to regenerate AI guidance and ensure the latest slash commands are active.
