+# 🌱 Spec Kit
+
+*Build high-quality software faster.*
+
+**An effort to allow organizations to focus on product scenarios rather than writing undifferentiated code with the help of Spec-Driven Development.**
+
+## 🤔 What is Spec-Driven Development?
+
+Spec-Driven Development **flips the script** on traditional software development. For decades, code has been king — specifications were just scaffolding we built and discarded once the "real work" of coding began. Spec-Driven Development changes this: **specifications become executable**, directly generating working implementations rather than just guiding them.
+
+## Getting Started
+
+- [Installation Guide](installation.md)
+- [Quick Start Guide](quickstart.md)
+
+## 📚 Core Philosophy
+
+Spec-Driven Development is a structured process that emphasizes:
+
+- **Intent-driven development** where specifications define the "_what_" before the "_how_"
+- **Rich specification creation** using guardrails and organizational principles
+- **Multi-step refinement** rather than one-shot code generation from prompts
+- **Heavy reliance** on advanced AI model capabilities for specification interpretation
+
+## 🌟 Development Phases
+
+| Phase | Focus | Key Activities |
+|-------|-------|----------------|
+| **0-to-1 Development** ("Greenfield") | Generate from scratch | <ul><li>Start with high-level requirements</li><li>Generate specifications</li><li>Plan implementation steps</li><li>Build production-ready applications</li></ul> |
+| **Creative Exploration** | Parallel implementations | <ul><li>Explore diverse solutions</li><li>Support multiple technology stacks & architectures</li><li>Experiment with UX patterns</li></ul> |
+| **Iterative Enhancement** ("Brownfield") | Brownfield modernization | <ul><li>Add features iteratively</li><li>Modernize legacy systems</li><li>Adapt processes</li></ul> |
+
+## 🎯 Experimental Goals
+
+Our research and experimentation focus on:
+
+### Technology Independence
+- Create applications using diverse technology stacks
+- Validate the hypothesis that Spec-Driven Development is a process not tied to specific technologies, programming languages, or frameworks
+
+### Enterprise Constraints
+- Demonstrate mission-critical application development
+- Incorporate organizational constraints (cloud providers, tech stacks, engineering practices)
+- Support enterprise design systems and compliance requirements
+
+### User-Centric Development
+- Build applications for different user cohorts and preferences
+- Support various development approaches (from vibe-coding to AI-native development)
+
+### Creative & Iterative Processes
+- Validate the concept of parallel implementation exploration
+- Provide robust iterative feature development workflows
+- Extend processes to handle upgrades and modernization tasks

+# Installation Guide
+
+## 🔧 Prerequisites
+
+- **Linux/macOS** (or WSL2 on Windows)
+- AI coding agent: [Claude Code](https://www.anthropic.com/claude-code), [GitHub Copilot](https://code.visualstudio.com/), or [Gemini CLI](https://github.com/google-gemini/gemini-cli)
+- [uv](https://docs.astral.sh/uv/) for package management
+- [Python 3.11+](https://www.python.org/downloads/)
+- [Git](https://git-scm.com/downloads)
+
+## Installation
+
+### Initialize a New Project
+
+The easiest way to get started is to initialize a new project:
+
+```bash
+uvx --from git+https://github.com/github/spec-kit.git specify init <PROJECT_NAME>
+```
+
+Or initialize in the current directory:
+
+```bash
+uvx --from git+https://github.com/github/spec-kit.git specify init --here
+```
+
+### Specify AI Agent
+
+You can proactively specify your AI agent during initialization:
+
+```bash
+uvx --from git+https://github.com/github/spec-kit.git specify init <project_name> --ai claude
+uvx --from git+https://github.com/github/spec-kit.git specify init <project_name> --ai gemini
+uvx --from git+https://github.com/github/spec-kit.git specify init <project_name> --ai copilot
+```
+
+### Ignore Agent Tools Check
+
+If you prefer to get the templates without checking for the right tools:
+
+```bash
+uvx --from git+https://github.com/github/spec-kit.git specify init <project_name> --ai claude --ignore-agent-tools
+```
+
+## Verification
+
+After initialization, you should see the following commands available in your AI agent:
+- `/specify` - Create specifications
+- `/plan` - Generate implementation plans  
+- `/tasks` - Break down into actionable tasks
+
+## 🔍 Troubleshooting
+
+### Git Credential Manager on Linux
+
+If you're having issues with Git authentication on Linux, you can install Git Credential Manager:
+
+```bash
+#!/usr/bin/env bash
+set -e
+echo "Downloading Git Credential Manager v2.6.1..."
+wget https://github.com/git-ecosystem/git-credential-manager/releases/download/v2.6.1/gcm-linux_amd64.2.6.1.deb
+echo "Installing Git Credential Manager..."
+sudo dpkg -i gcm-linux_amd64.2.6.1.deb
+echo "Configuring Git to use GCM..."
+git config --global credential.helper manager
+echo "Cleaning up..."
+rm gcm-linux_amd64.2.6.1.deb
+```

+# ⚡ Quick Start Guide
+
+This guide will help you get started with Spec-Driven Development using Spec Kit.
+
+## The 4-Step Process
+
+### 1. Install Specify
+
+Initialize your project depending on the coding agent you're using:
+
+```bash
+uvx --from git+https://github.com/github/spec-kit.git specify init <PROJECT_NAME>
+```
+
+### 2. Create the Spec
+
+Use the `/specify` command to describe what you want to build. Focus on the **what** and **why**, not the tech stack.
+
+```bash
+/specify Build an application that can help me organize my photos in separate photo albums. Albums are grouped by date and can be re-organized by dragging and dropping on the main page. Albums are never in other nested albums. Within each album, photos are previewed in a tile-like interface.
+```
+
+### 3. Create a Technical Implementation Plan
+
+Use the `/plan` command to provide your tech stack and architecture choices.
+
+```bash
+/plan The application uses Vite with minimal number of libraries. Use vanilla HTML, CSS, and JavaScript as much as possible. Images are not uploaded anywhere and metadata is stored in a local SQLite database.
+```
+
+### 4. Break Down and Implement
+
+Use `/tasks` to create an actionable task list, then ask your agent to implement the feature.
+
+## Detailed Example: Building Taskify
+
+Here's a complete example of building a team productivity platform:
+
+### Step 1: Define Requirements with `/specify`
+
+```text
+Develop Taskify, a team productivity platform. It should allow users to create projects, add team members,
+assign tasks, comment and move tasks between boards in Kanban style. In this initial phase for this feature,
+let's call it "Create Taskify," let's have multiple users but the users will be declared ahead of time, predefined.
+I want five users in two different categories, one product manager and four engineers. Let's create three
+different sample projects. Let's have the standard Kanban columns for the status of each task, such as "To Do,"
+"In Progress," "In Review," and "Done." There will be no login for this application as this is just the very
+first testing thing to ensure that our basic features are set up. For each task in the UI for a task card,
+you should be able to change the current status of the task between the different columns in the Kanban work board.
+You should be able to leave an unlimited number of comments for a particular card. You should be able to, from that task
+card, assign one of the valid users. When you first launch Taskify, it's going to give you a list of the five users to pick
+from. There will be no password required. When you click on a user, you go into the main view, which displays the list of
+projects. When you click on a project, you open the Kanban board for that project. You're going to see the columns.
+You'll be able to drag and drop cards back and forth between different columns. You will see any cards that are
+assigned to you, the currently logged in user, in a different color from all the other ones, so you can quickly
+see yours. You can edit any comments that you make, but you can't edit comments that other people made. You can
+delete any comments that you made, but you can't delete comments anybody else made.
+```
+
+### Step 2: Refine the Specification
+
+After the initial specification is created, clarify any missing requirements:
+
+```text
+For each sample project or project that you create there should be a variable number of tasks between 5 and 15
+tasks for each one randomly distributed into different states of completion. Make sure that there's at least
+one task in each stage of completion.
+```
+
+Also validate the specification checklist:
+
+```text
+Read the review and acceptance checklist, and check off each item in the checklist if the feature spec meets the criteria. Leave it empty if it does not.
+```
+
+### Step 3: Generate Technical Plan with `/plan`
+
+Be specific about your tech stack and technical requirements:
+
+```text
+We are going to generate this using .NET Aspire, using Postgres as the database. The frontend should use
+Blazor server with drag-and-drop task boards, real-time updates. There should be a REST API created with a projects API,
+tasks API, and a notifications API.
+```
+
+### Step 4: Validate and Implement
+
+Have your AI agent audit the implementation plan:
+
+```text
+Now I want you to go and audit the implementation plan and the implementation detail files.
+Read through it with an eye on determining whether or not there is a sequence of tasks that you need
+to be doing that are obvious from reading this. Because I don't know if there's enough here.
+```
+
+Finally, implement the solution:
+
+```text
+implement specs/002-create-taskify/plan.md
+```
+
+## Key Principles
+
+- **Be explicit** about what you're building and why
+- **Don't focus on tech stack** during specification phase
+- **Iterate and refine** your specifications before implementation
+- **Validate** the plan before coding begins
+- **Let the AI agent handle** the implementation details
+
+## Next Steps
+
+- Read the [complete methodology](../spec-driven.md) for in-depth guidance
+- Check out more examples in the repository
+- Explore the source code on GitHub
