+# Getting Started with devx
+
+This guide walks you through installing devx, configuring it for your project,
+and setting up a complete CI/CD pipeline.
+
+## Prerequisites
+
+- **Python 3.12+**
+- **A Gitea instance** with Actions enabled
+- **A Gitea API token** with repo, workflow, and organization scopes
+- **(Optional) Vikunja API token** for task tracking integration
+
+## Installation
+
+devx is published to the Gitea PyPI registry. Configure pip to use it:
+
+```bash
+# Configure Gitea PyPI registry
+pip config set global.extra-index-url https://git.oblachno.oblachno.fyi/api/packages/oblachno-oss/pypi/simple
+
+# Install devx
+pip install devx
+```
+
+Or install from source:
+
+```bash
+git clone https://git.oblachno.oblachno.fyi/oblachno-oss/devx.git
+cd devx
+make setup
+```
+
+## Quick Start
+
+### 1. Configure environment variables
+
+Create a `.env` file in your project root:
+
+```bash
+CI_GITEA_TOKEN=your_gitea_api_token
+VIKUNJA_TOKEN=your_vikunja_api_token  # optional
+```
+
+### 2. Add devx to your project
+
+Add devx to your `pyproject.toml`:
+
+```toml
+[project]
+dependencies = [
+    "devx>=0.26.0",
+]
+
+[project.optional-dependencies]
+dev = [
+    "devx[dev]>=0.26.0",
+]
+```
+
+### 3. Set up the Makefile
+
+devx provides a shared Makefile fragment. Add this to your `Makefile`:
+
+```makefile
+include devx.mak
+```
+
+Run `devx tools setup` to install all development tools (actionlint, git-cliff,
+tea CLI, etc.) and configure pre-commit hooks.
+
+### 4. Create the docs structure
+
+devx expects a `docs/` directory with at minimum:
+
+```
+docs/
+├── index.md          # Documentation home page
+├── mapping.json      # Wiki page title mappings
+├── user/             # User-facing documentation
+│   └── cli-commands.md
+└── tech/             # Technical documentation
+    ├── architecture.md
+    └── ci-cd-workflow.md
+```
+
+Example `docs/mapping.json`:
+
+```json
+{
+  "index.md": "Home",
+  "user/cli-commands.md": "CLI-Commands",
+  "tech/architecture.md": "Architecture",
+  "tech/ci-cd-workflow.md": "CI-CD-Workflow"
+}
+```
+
+### 5. Set up CI workflows
+
+Create `.gitea/workflows/ci.yml` and `.gitea/workflows/post-merge.yml` in your
+project. See the [CI/CD Workflow guide](../tech/ci-cd-workflow.md) for details.
+
+### 6. Configure release settings
+
+Add a `cliff.toml` for git-cliff-based versioning:
+
+```bash
+devx tools generate-cliff-config
+```
+
+Add `[tool.devx]` section to `pyproject.toml` for project-specific config:
+
+```toml
+[tool.devx]
+# Vikunja project ID for task tracking
+vikunja_project_id = 6
+
+[tool.devx.classify]
+# File patterns that are workflow-only (no release needed)
+workflow_only = [
+    ".gitea/**",
+    "docs/**",
+    "tests/**",
+    "AGENTS.md",
+    "README.md",
+    "CHANGELOG.md",
+]
+```
+
