 # Forge
 
-Forge automates the software development lifecycle from feature ideation through code delivery using AI-powered planning and execution. It connects Jira, GitHub, and Claude to transform tickets into shipped code with human approval gates at each stage.
+Forge automates the software development lifecycle from ticket creation through code delivery using AI-powered planning and execution. It connects Jira, GitHub, and Claude to transform tickets into shipped code with human approval gates at each stage.
+
+Forge supports three distinct, user-facing workflows depending on your ticket type and project requirements.

+## Supported Workflows
+
+### 🚀 Feature Workflow
+Used for long-term or large-scale product changes where requirements need detailed definition and structural design before writing code.
+* **Process**: Progresses from initial Jira Feature to automated PRD generation, Technical Spec creation, Epic decomposition, and task implementation with rigorous human review gates at every planning step.
+* **When to use**: Choose this workflow for net-new features, substantial architectural modifications, or projects requiring collaborative product/engineering alignment on requirements before any code is touched.
+* **More Info**: Read the [Feature Workflow Guide](guide/feature-workflow.md).
+
+### 🐛 Bug Workflow
+Designed specifically for triaging, diagnosing, and resolving software defects efficiently.
+* **Process**: Forge reproduces the issue inside an isolated sandbox, automatically drafts a detailed Root Cause Analysis (RCA) presenting alternative fix options, generates a concrete fix plan upon option selection, and implements the verified fix.
+* **When to use**: Choose this workflow for reported bugs, unexpected crashes, test regressions, or any ticket where the root cause is unknown or multiple fix strategies need to be evaluated first.
+* **More Info**: Read the [Bug Workflow Guide](guide/bug-workflow.md).
+
+### 🛠️ Task Workflow
+Tailored for already-scoped, standalone tickets or task takeovers that bypass the extended feature planning and decomposition phases.
+* **Process**: Forge takes existing, clear engineering instructions directly from a Jira Task or Epic, generates a direct implementation plan, executes the changes in a sandbox, repairs CI, and opens a review-ready Pull Request.
+* **When to use**: Choose this workflow for well-defined engineering chores, minor refactors, simple library upgrades, or whenever the technical implementation steps are already pre-determined and agreed upon.
+* **More Info**: Read the [Task Workflow Guide](guide/task-workflow.md).
