+# stamp
+
+A language-agnostic, changesets-style versioning and changelog tool. Works with any project type and supports monorepos.
+
+## Overview
+
+`stamp` is inspired by the [Changesets](https://github.com/changesets/changesets) workflow, but without the Node.js dependency. It works by having contributors add small **stamp files** (`.stamp/*.md`) alongside their code changes. When it's time to release, `stamp` consumes those files, bumps versions, updates changelogs, creates git tags, and publishes releases to GitHub or Gitea.
+
+## Installation
+
+Via [Mise](https://mise.jdx.dev/):
+
+```toml
+# mise.toml
+[tools]
+"go:github.com/thokra/stamp/cmd/stamp" = "latest"
+```
+
+Or with `go install`:
+
+```sh
+go install github.com/thokra/stamp/cmd/stamp@latest
+```
+
+Or build from source:
+
+```sh
+git clone https://github.com/thokra/stamp
+cd stamp
+go build -o bin/stamp ./cmd/stamp
+```
+
+## Quick Start
+
+### 1. Create `stamp.toml` at the root of your repository
+
+```toml
+[[projects]]
+name    = "my-app"
+path    = "."
+version = "0.1.0"
+
+  [projects.publish]
+  tags      = true
+  releases  = true
+  artifacts = ["dist/my-app-*"]
+```
+
+See [`examples/stamp.toml`](examples/stamp.toml) for a fully annotated example.
+
+### 2. Add a stamp file when making a change
+
+```sh
+# Interactive
+stamp add
+
+# Non-interactive (great for scripts and AI agents)
+stamp add --project=my-app --bump=minor --message="Added new feature"
+```
+
+This creates a `.stamp/<random-slug>.md` file. Commit it alongside your code.
+
+### 3. Check pending stamps
+
+```sh
+stamp status
+```
+
+```
+📦 Pending stamps: 2
+
+  PROJECT   CURRENT  NEXT   BUMP   STAMPS
+  -------   -------  ----   ----   ------
+  my-app    1.2.3    1.3.0  minor  2
+```
+
+### 4. Release
+
+```sh
+# Bump versions and update changelogs
+stamp version
+
+# Create git tags, GitHub/Gitea releases, and upload artifacts
+STAMP_REPO=owner/repo stamp publish
+```
+
+## Commands
+
+### `stamp add`
+
+Creates a new stamp file describing a change.
+
+| Flag | Description |
+|------|-------------|
+| `--project` | Project name to include (repeatable) |
+| `--bump` | Bump type: `major`, `minor`, `patch`, `premajor`, `preminor`, `prepatch`, `prerelease` |
+| `--message` | Description of the change |
+| `--no-interactive` | Disable interactive prompts (requires `--project`, `--bump`, `--message`) |
+| `--slug` | Custom filename slug (default: auto-generated, e.g. `brave-river`) |
+
+### `stamp status`
+
+Shows all pending stamp files and the projected next version for each project.
+
+| Flag | Description |
+|------|-------------|
+| `--json` | Output as JSON |
+
+### `stamp version`
+
+Consumes all pending stamp files, bumps versions in `stamp.toml`, and prepends a new entry to each project's `CHANGELOG.md`. Then stages and commits the changes via git.
+
+| Flag | Description |
+|------|-------------|
+| `--snapshot <id>` | Create a pre-release with the given identifier (e.g. `alpha`, `rc`) |
+| `--no-commit` | Apply changes without creating a git commit |
+
+### `stamp publish`
+
+Creates git tags and publishes releases (with optional artifact uploads) to GitHub or Gitea.
+
+| Flag | Description |
+|------|-------------|
+| `--dry-run` / `-n` | Print what would happen without executing |
+| `--project` | Only publish a specific project |
+
+Requires `STAMP_REPO=owner/repo` to be set. Detects GitHub vs Gitea automatically via the `GITEA_BASE_URL` environment variable.
+
+Tag format: `<name>@v<version>` (e.g. `my-app@v1.3.0`).
+
+### `stamp comment`
+
+Posts or updates a PR comment summarising pending stamps. Useful in CI to remind contributors to add stamp files or to show reviewers what versions will change.
+
+- **No stamps found** → warns the author with instructions on how to add one.
+- **Stamps found** → shows a table of affected projects and their next versions.
+
+| Flag | Description |
+|------|-------------|
+| `--pr` | Pull request number (required) |
+| `--repo` | Repository slug `owner/repo` (defaults to `STAMP_REPO` or `GITHUB_REPOSITORY`) |
+
+## Stamp File Format
+
+Stamp files live in `.stamp/` and use Markdown with YAML or TOML frontmatter.
+
+### YAML (default)
+
+```markdown
+---
+bumps:
+  my-app: minor
+  my-lib: patch
+---
+
+Short description used as the changelog entry.
+
+- Optional bullet points for more detail.
+```
+
+### TOML
+
+```markdown
++++
+[bumps]
+my-app = "minor"
++++
+
+Short description.
+```
+
+### Bump types
+
+| Type | Description |
+|------|-------------|
+| `major` | Breaking change — `1.2.3` → `2.0.0` |
+| `minor` | New feature — `1.2.3` → `1.3.0` |
+| `patch` | Bug fix — `1.2.3` → `1.2.4` |
+| `premajor` | Pre-release major — `1.2.3` → `2.0.0-alpha.0` |
+| `preminor` | Pre-release minor — `1.2.3` → `1.3.0-alpha.0` |
+| `prepatch` | Pre-release patch — `1.2.3` → `1.2.4-alpha.0` |
+| `prerelease` | Increment pre-release — `1.2.4-rc.0` → `1.2.4-rc.1` |
+
+## Configuration Reference (`stamp.toml`)
+
+```toml
+# Global settings (all optional)
+[config]
+base_branch   = "main"   # Base branch for PR change detection (default: main)
+changeset_dir = ".stamp" # Directory for stamp files (default: .stamp)
+
+[[projects]]
+name      = "my-app"
+path      = "apps/my-app"    # Path relative to repo root
+version   = "1.2.3"          # Current version — updated by `stamp version`
+changelog = "CHANGELOG.md"   # Relative to path (default: CHANGELOG.md)
+
+  [projects.publish]
+  tags      = true
+  releases  = true
+  artifacts = [
+    "apps/my-app/dist/my-app-linux-amd64",
+    "apps/my-app/dist/my-app-darwin-arm64",
+  ]
+```
+
+## Environment Variables
+
+| Variable | Purpose |
+|----------|---------|
+| `STAMP_REPO` | Repository slug `owner/repo` — required for `publish` and `comment` |
+| `GITHUB_TOKEN` | GitHub personal access token for releases and PR comments |
+| `GITEA_TOKEN` | Gitea access token |
+| `GITEA_BASE_URL` | Gitea instance URL (e.g. `https://gitea.example.com`) — also enables Gitea mode |
