 Format: [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
 
+## [1.6.2] - 2026-07-11
+
+### Changed
+
+- **`task ci` now runs `go tool staticcheck ./...`** — runs between `go vet` and `go test`; matches the step already present in the Gitea CI workflow
+
+### Fixed
+
+- **SA4006 in `TestLatestTagTagsIterFails`** — `err` from `gogit.PlainOpen` was assigned then immediately overwritten without being read; added the missing `if err != nil { t.Fatalf(...) }` check
+
+## [1.6.1] - 2026-07-11
+
+### Fixed
+
+- **CI root-permission failures** — four tests that used `os.Chmod` to force error paths were failing in Docker CI (which runs as root, where chmod has no enforcement effect); each now skips with `os.Getuid() == 0`; the gitutil test had broken skip logic that only fired if `Chmod` itself errored — replaced with the same upfront UID check
+
+## [1.6.0] - 2026-07-11
+
+### Added
+
+- **Gradle support** — new `internal/gradle` package; reads and writes the version assignment in `build.gradle` (Groovy DSL, single-quoted) and `build.gradle.kts` (Kotlin DSL, double-quoted); original quote style preserved on write; `regexp.QuoteMeta` ensures version strings with dots or special chars are safe
+- **`gradle.build_file` / `gradle.build_files` config** — opt-in, no default; `build_files` list overrides `build_file` for multi-module projects; follows the same multi-value pattern as `maven.pom_paths` and `node.package_jsons`
+- **`--gradle <path>` flag** — overrides `gradle.build_file` from config and clears `gradle.build_files`; mirrored in verbose config table as `gradle.paths`
+- **`FuzzReadVersion` / `FuzzWriteVersion`** in `internal/gradle` — 100% per-package statement coverage maintained across all 13 packages
+
+## [1.5.1] - 2026-07-11
+
+### Added
+
+- **Documentation site** — Hugo + Geekdoc theme; content covers installation, CLI reference, configuration, CI integration, and changelog; deployed to `gh-pages` via Gitea CI on push to `main`
+- **`docs:setup` / `docs:serve` / `docs:build` Taskfile tasks** — `docs:setup` downloads the Geekdoc theme bundle (idempotent); `docs:serve` runs Hugo with live reload; `docs:build` produces a minified static site
+- **`FuzzUpdate`** in `internal/changelog` — fuzzes arbitrary existing file content paired with a commit message, covering the `\n## [` insertion logic and idempotency guard
+- **`FuzzWriteVersion`** in `internal/node` — mirrors `FuzzReplaceProjectVersion` in `internal/maven`; fuzzes arbitrary JSON content with arbitrary old/new version strings
+
+### Changed
+
+- **CLAUDE.md** — new "Fuzzing" section: authoritative table of which packages require fuzz tests and why, list of exempt packages with rationale, seed corpus guidelines
+
+## [1.5.0] - 2026-07-11
+
+### Added
+
+- **Multi-module Maven support** — `maven.pom_paths: [...]` lists multiple `pom.xml` paths (e.g. root + sub-modules); overrides `pom_path`; each path is updated and committed in the same release commit
+- **Node.js `package.json` support** — opt-in via `node.package_json` (single path) or `node.package_jsons` (list, overrides the single path); version is bumped in-place alongside `pom.xml` and `CHANGELOG.md`
+- **`git.bump_rules` config** — controls which version component each commit type bumps: `breaking`, `feat`, `fix` each accept `"patch"` (default) or `"minor"`; allows e.g. `feat: "minor"` to bump the minor component instead of patch
+- **Injectable function vars in `cmd/main.go`** — `absPath`, `gitAllCommits`, `gitCommitsSince`, `gitCommitFiles` are now package-level vars overridable in tests to inject errors, enabling 100% per-package statement coverage across all 12 packages
+
+### Changed
+
+- **`--pom` flag** now clears `maven.pom_paths` before setting `maven.pom_path`, ensuring the CLI flag always wins over a multi-path config file entry
+- **`version.Next()` signature** — accepts a `map[commits.Type]semver.BumpLevel` bump-rules map as a sixth parameter; `nil` defaults to all-patch (no change to existing behaviour)
+- **Verbose config table** — now includes `git.bump_rules.breaking/feat/fix`, `maven.pom_paths` (effective list), and `node.paths` rows
+
+## [1.4.0] - 2026-07-11
+
+### Added
+
+- **GitHub release support** — new `internal/ghclient` package (minimal HTTP client, no SDK); configured via `github.token` + `github.repo` in `.releaser.yml` or `GITHUB_TOKEN` env var; GitHub takes precedence over GitLab when both are configured
+- **SSH agent push** — `gitutil.Push()` now attempts go-git SSH agent auth (`gitssh.NewSSHAgentAuth`) for `git@` / `ssh://` remotes before falling back to the system `git` binary; no extra configuration needed
+- **`--release-env-file` flag** — override the dotenv artifact path (relative to repo root; default `release.env`); pass `""` to disable writing the file entirely (e.g. for local runs)
+- **`git.releasable_types` config** — opt-in list of commit types that count as releasable (`fix`, `feat`, `breaking`); defaults to all three; useful for maintenance branches where some types should not trigger a release
+- **`commits.Group()`, `ExtractSubject()`, `ReleasableSet()`** — exported helpers in `internal/commits`; shared by `notes` and `changelog`, eliminating duplicated grouping and subject-extraction logic
+- **CHANGELOG deduplication guard** — `changelog.Update()` is now idempotent; skips the write if a `## [version]` section already exists, preventing duplicate entries on CI reruns
+- **Publisher interface** — `releasePublisher` interface + `buildPublisher()` in `cmd/main.go`; GitLab and GitHub are now interchangeable backends; new providers can be added without touching the orchestration logic
+- **`artifacts: reports: dotenv: release.env`** in `.releaser.gitlab-ci.yml` — exposes `NEXT_VERSION` to downstream GitLab CI jobs out of the box
+
+### Changed
+
+- **Always load config sources** — `LoadWithSources()` is now called unconditionally instead of only in `--verbose` mode; single code path, no behavioural difference
+- **`version.Next()` signature** — accepts a `map[commits.Type]bool` releasable set as a fifth parameter; `nil` defaults to all three types (no change to existing behaviour)
+- **Verbose config table** — now includes `git.releasable_types`, `github.token`, and `github.repo` rows
+
+## [1.3.0] - 2026-07-07
+
+### Added
+
+- **`release.env` dotenv artifact** — on every real release (not `--dry-run`) a `release.env` file is written to the repository root containing `NEXT_VERSION=<tag>`; the file is never committed, allowing GitLab CI to expose it as a dotenv artifact and pass the version to downstream jobs (deploy, notify, etc.)
+
+## [1.2.0] - 2026-07-07
+
+### Added
+
+- **`--verbose` flag** — prints a configuration table (each key, its value, and source: `default` / `config file` / `env: VARNAME` / `flag: --name`), lists every commit since the last tag with its parsed type and bump decision, and shows the final version choice; all output goes to stderr
+- **Colored, structured CLI output** — progress lines use `·` / `✓` / `!` prefix symbols; `--verbose` mode uses `▸` section headers (configuration / branch / commits / version); commit type column colored by kind (cyan=feat, green=fix, red=breaking); config source tags colored; respects `NO_COLOR` and `TERM=dumb`; auto-disabled when stderr is not a TTY
+- **Name and version header** — `releaser  vX.Y.Z` printed to stderr at the start of every invocation
+
+### Changed
+
+- **Default `tag_prefix` is now empty** — tags are bare version numbers (`1.2.3`) by default; add `tag_prefix: "v"` to `.releaser.yml` or pass `--tag-prefix v` to opt in to the `v`-prefixed convention
+
+## [1.1.0] - 2026-07-07
+
+### Added
+
+- **CHANGELOG.md auto-update** — every release now writes a new dated section to `CHANGELOG.md` (grouped by Breaking Changes / Added / Fixed), committed alongside `pom.xml` in the release commit; file is created if it does not exist
+- **`--changelog-file` flag** — override the default `CHANGELOG.md` path (e.g. `--changelog-file CHANGES.md`)
+- **`--init` flag** — scaffolds a fully-commented default `.releaser.yml` in the repository root; errors if the file already exists
+- **`CommitFiles`** in `gitutil` — internal helper that stages multiple files before a single commit, used to bundle `pom.xml` + `CHANGELOG.md` in one release commit
+
+### Fixed
+
+- **Push without token** — go-git's HTTPS transport does not use the system credential store; when `GITLAB_TOKEN` is unset the push now delegates to the `git` CLI so credential helpers, SSH agents, and `netrc` all work as expected
+
+## [0.4.2] - 2026-07-07
+
+### Fixed
+
+- **CI build step** — `go build ./cmd/...` failed with "output already exists and is a directory" because Go tried to write a binary named `cmd`, conflicting with the source directory; fixed by passing `-o /dev/null`
+- **Optional pom.xml** — releaser no longer fails when `pom.xml` (or the configured `maven.pom_path`) does not exist; it logs a notice and proceeds directly to tag and push, making the tool usable in non-Maven projects
+
 ## [0.4.0] - 2026-07-07

+# CLAUDE.md — project guidelines for releaser
+
+## Overview
+
+`releaser` is a single-binary Go tool for GitFlow-based release automation. It targets Conventional Commits, versioned release branches (`release/X.Y`), and GitLab / GitHub release creation.
+
+## Architecture
+
+```
+cmd/main.go          — CLI entrypoint (cobra), run() pipeline, verbose output
+internal/branch/     — branch name parser → major/minor
+internal/changelog/  — CHANGELOG.md writer
+internal/commits/    — Conventional Commits parser (non-strict)
+internal/config/     — .releaser.yml loader + env var overlay + source tracking
+internal/ghclient/   — minimal GitHub Releases API client
+internal/gitutil/    — go-git helpers: tag discovery, commit walker, push
+internal/glclient/   — minimal GitLab Releases API client
+internal/maven/      — pom.xml version reader/writer
+internal/node/       — package.json version reader/writer
+internal/notes/      — release notes body generator
+internal/version/    — semver next-version calculator
+```
+
+## Code conventions
+
+- **No third-party test frameworks** — stdlib `testing` only.
+- **No interfaces for mocking** — inject function variables (`var absPath = filepath.Abs`) to test error paths.
+- **No comments explaining what** — only comments explaining *why* (hidden constraints, invariants, non-obvious workarounds).
+- **No error handling for impossible paths** — trust internal invariants; only validate at system boundaries.
+- **No abstractions ahead of need** — three similar lines beats a premature helper.
+
+## Test coverage
+
+**100% per-package statement coverage is required** across all packages. Run:
+
+```bash
+go test ./... -cover
+```
+
+Every package must show `coverage: 100.0% of statements`.
+
+Strategies used in this project:
+- **Error path injection**: override `var absPath`, `var gitAllCommits`, etc. to return injected errors.
+- **Filesystem tricks**: `os.Mkdir` where a file is expected (invisible to go-git dirty check; fails os.WriteFile/os.ReadFile); `os.Chmod(..., 0444)` to make files read-only.
+- **Null byte paths**: `"path\x00name"` causes `os.Stat` to return `EINVAL` (not `ErrNotExist`), useful for testing stat-error paths that differ from file-not-found.
+- **In-memory git repos**: use go-git `PlainInit` + local bare remote for push tests.
+- **Direct function calls**: call unexported helpers (e.g. `printVerboseConfig`) directly with crafted inputs to cover branches that are dead via normal CLI flow.
+
+## Fuzzing
+
+**Every package that parses free-form text or reads/writes arbitrary file content must have at least one fuzz test.** Run the full seed corpus with:
+
+```bash
+go test -run='^Fuzz' ./...
+```
+
+All seed cases must pass. The table below is authoritative — keep it in sync when adding packages or parsers:
+
+| Package | Fuzz target(s) | Why |
+|---------|---------------|-----|
+| `internal/branch` | `FuzzParse` | parses branch name strings |
+| `internal/changelog` | `FuzzUpdate` | rewrites arbitrary existing file content |
+| `internal/commits` | `FuzzParse` | parses arbitrary commit message strings |
+| `internal/gradle` | `FuzzReadVersion`, `FuzzWriteVersion` | reads/rewrites arbitrary Gradle build file content |
+| `internal/glclient` | `FuzzEncodeProjectPath` | encodes arbitrary project path strings |
+| `internal/maven` | `FuzzReadVersion`, `FuzzReplaceProjectVersion` | reads/rewrites arbitrary XML file content |
+| `internal/node` | `FuzzReadVersion`, `FuzzWriteVersion` | reads/rewrites arbitrary JSON file content |
+| `internal/notes` | `FuzzGenerate` | generates notes from arbitrary commit messages |
+
+Packages **not** requiring fuzz tests (no free-form text parsing): `internal/config` (yaml.v3 handles parsing), `internal/ghclient` (HTTP client, no text parsing), `internal/gitutil` (git operations), `internal/version` (typed inputs only), `cmd` (CLI orchestration). When adding a new package, check whether it parses text or rewrites files — if yes, add a row above.
+
+Fuzz seed corpus guidelines:
+- Include a realistic happy-path input as the first seed.
+- Include empty string, binary/non-UTF-8 bytes (`"\x00\xff"`), and inputs that stress known branches (e.g. existing `## [version]` heading for changelog).
+- The fuzz body must never assert on return values — only verify no panic.
+
+## Dependency rules
+
+- **No new external dependencies** unless absolutely necessary. The project deliberately avoids pulling in large ecosystems.
+- go-git (`github.com/go-git/go-git/v5`) for all git operations.
+- cobra for CLI parsing.
+- gopkg.in/yaml.v3 for config.
+
+## Config design
+
+- New config fields go in the appropriate `*Config` struct in `internal/config/config.go`.
+- `defaultSources()` must be updated to include every new key.
+- `LoadWithSources` overlay detection must cover every new field.
+- `printVerboseConfig` in `cmd/main.go` must show every new config value.
+
+## Multi-value config pattern
+
+When a config supports both a single value and multiple values (like `pom_path` / `pom_paths`):
+- Single field: `PomPath string`
+- Multi field: `PomPaths []string`
+- `EffectivePomPaths()` method: `PomPaths` wins if non-empty, else `PomPath` if set, else default.
+- `--pom` CLI flag clears `PomPaths` and sets `PomPath` only.

 A CI-friendly release automation tool for GitFlow workflows using Conventional Commits.
 
+**[Documentation](https://releaser.k3nny.fr)**
+
 ## Problem
 
 Standard tools like `semantic-release` are designed for trunk-based development. In a GitFlow setup with versioned release branches (`release/1.1`, `release/1.2`), they either fail to respect the branch's version range or require brittle configuration.
 
-`releaser` is built for this exact workflow: it reads the branch name to pin the `major.minor`, parses Conventional Commits to determine the patch increment, and handles everything from `pom.xml` update to GitLab tag+release creation.
+`releaser` is built for this exact workflow: it reads the branch name to pin the `major.minor`, parses Conventional Commits to determine the patch increment, and handles everything from `pom.xml` update to GitLab/GitHub tag+release creation.
 
 ## How it works
 
 ```
 release/1.2 branch
-  └─ last tag: v1.2.3 (or none → start at v1.2.0)
+  └─ last tag: 1.2.3 (or none → start at 1.2.0)
        └─ commits since tag → Conventional Commits analysis
-            └─ next version: v1.2.4
+            └─ next version: 1.2.4
 ```
 
 1. **Branch parsing** — extracts `major.minor` from branch name (e.g. `release/1.2` → `1.2`)
 2. **Tag discovery** — finds the latest tag matching `major.minor.*` on the current branch
 3. **Commit analysis** — parses Conventional Commits between last tag and HEAD
 4. **Version bump** — increments patch (the minor is owned by the branch)
-5. **Release** — updates `pom.xml`, commits, tags, creates GitLab release
+5. **Release** — updates `pom.xml` / `package.json` / `build.gradle`, commits, tags, creates GitLab or GitHub release
 
 ## Version bump rules
 
-| Commit type      | Bump    | Notes                                      |
-|------------------|---------|--------------------------------------------|
-| `fix:`           | patch   |                                            |
-| `feat:`          | patch   | minor is pinned to branch                  |
-| `feat!:` / `BREAKING CHANGE` | patch | same — branch defines the minor boundary |
-| `chore:`, `docs:`, etc. | none |                                        |
-| unparseable msg  | none    | non-strict mode: silently ignored          |
+By default, all releasable commits bump the **patch** component (minor is pinned to the branch). You can override this per commit type via `git.bump_rules` in `.releaser.yml`:
+
+| Commit type      | Default | Configurable via `bump_rules`                  |
+|------------------|---------|------------------------------------------------|
+| `fix:`           | patch   | `fix: "minor"` to bump minor instead           |
+| `feat:`          | patch   | `feat: "minor"` to bump minor instead          |
+| `feat!:` / `BREAKING CHANGE` | patch | `breaking: "minor"` to bump minor  |
+| `chore:`, `docs:`, etc. | none   | —                                       |
+| unparseable msg  | none    | non-strict mode: silently ignored              |

+- [x] ~~`--verbose` flag~~ — ✓ shipped v1.2.0 (shows config sources, commit analysis, version decision)
+- [x] ~~Colored, structured CLI output~~ — ✓ shipped v1.2.0 (`·` / `✓` / `!` symbols, `▸` section headers in verbose, TTY-aware ANSI colors)
+- [x] ~~Name and version header on every run~~ — ✓ shipped v1.2.0
+- [x] ~~Default tag prefix changed to empty~~ — ✓ shipped v1.2.0 (bare `1.2.3` tags by default; opt in to `v` prefix via config)
+- [x] ~~`release.env` dotenv artifact~~ — ✓ shipped v1.3.0 (`NEXT_VERSION=<tag>` written on every release for GitLab CI downstream jobs)
+- [x] ~~GitHub release support~~ — ✓ shipped v1.4.0 (`internal/ghclient`, `GITHUB_TOKEN` env, `github.token`/`github.repo` config; GitHub takes precedence over GitLab)
+- [x] ~~SSH agent push~~ — ✓ shipped v1.4.0 (go-git `gitssh.NewSSHAgentAuth` for `git@`/`ssh://` remotes)
+- [x] ~~Configurable bump rules~~ — ✓ shipped v1.4.0 (`git.releasable_types` config; filter which commit types trigger a release)

+- [x] Configurable bump rules per commit type (`git.bump_rules.breaking/feat/fix: "minor" | "patch"`)
+- [x] 100% per-package statement coverage across all 12 packages
 
 ## Future / backlog
 
-- GitHub release support (parity with GitLab)
-- Multi-module Maven support (multiple `pom.xml` paths)
-- Gradle support (`build.gradle` / `build.gradle.kts`)
-- `package.json` version bump support (Node.js projects)
+- ~~Gradle support (`build.gradle` / `build.gradle.kts`)~~ — ✓ shipped v1.6.0 (`internal/gradle`; Groovy + Kotlin DSL; multi-module via `gradle.build_files`; `--gradle` flag)

+title: releaser
+---
+
+**CI-friendly release automation for GitFlow workflows using Conventional Commits.**
+
+Standard tools like `semantic-release` are designed for trunk-based development. In a GitFlow setup with versioned release branches (`release/1.1`, `release/1.2`), they either fail to respect the branch's version range or require brittle configuration.
+
+`releaser` is built for this exact workflow: it reads the branch name to pin the `major.minor`, parses Conventional Commits to determine the patch increment, and handles everything from `pom.xml` / `package.json` update to GitLab/GitHub tag and release creation.
+
+## How it works
+
+```
+release/1.2 branch
+  └─ last tag: 1.2.3 (or none → start at 1.2.0)
+       └─ commits since tag → Conventional Commits analysis
+            └─ next version: 1.2.4
+```
+
+1. **Branch parsing** — extracts `major.minor` from branch name (`release/1.2` → `1.2`)
+2. **Tag discovery** — finds the latest tag matching `major.minor.*` on the current branch
+3. **Commit analysis** — parses Conventional Commits between last tag and HEAD
+4. **Version bump** — increments patch (or minor, if configured via `bump_rules`)
+5. **Release** — updates `pom.xml` / `package.json`, commits, tags, creates GitLab or GitHub release

+title: Changelog
+weight: 50
+---
+
+## v1.6.0 — 2026-07-11
+
+### Added
+
+- **Gradle support** — opt-in via `gradle.build_file` (single path) or `gradle.build_files` (list, overrides single); supports both Groovy DSL (`version = '1.2.3'`) and Kotlin DSL (`version = "1.2.3"`); original quote style preserved on write; `--gradle <path>` CLI flag for one-off overrides
+
+## v1.5.1 — 2026-07-11
+
+### Added
+
+- **Documentation site** — Hugo + Geekdoc; installation, CLI reference, configuration, CI integration, and changelog pages; deployed to `gh-pages` via Gitea CI on push to `main`
+- **`FuzzUpdate`** in `internal/changelog` and **`FuzzWriteVersion`** in `internal/node` — complete fuzz coverage for all file-rewriting packages
+
+### Changed
+
+- **CLAUDE.md** — fuzzing completeness guidelines with authoritative table
+
+## v1.5.0 — 2026-07-11
+
+### Added
+
+- **Multi-module Maven support** — `maven.pom_paths: [...]` lists multiple `pom.xml` paths; overrides `pom_path`; each path is updated and committed in the same release commit
+- **Node.js `package.json` support** — opt-in via `node.package_json` (single path) or `node.package_jsons` (list); version bumped in-place alongside `pom.xml` and `CHANGELOG.md`
+- **`git.bump_rules` config** — controls which version component each commit type bumps: `breaking`, `feat`, `fix` each accept `"patch"` (default) or `"minor"`
+- **100% per-package statement coverage** across all 12 packages via injectable function vars
+
+### Changed
+
+- **`--pom` flag** now clears `maven.pom_paths` before setting `maven.pom_path`
+- **`version.Next()` signature** — accepts a bump-rules map as a sixth parameter; `nil` defaults to all-patch
+- **Verbose config table** — now includes `git.bump_rules.*`, `maven.pom_paths`, and `node.paths` rows
+
+## v1.4.0 — 2026-07-11
+
+### Added
+
+- **GitHub release support** — `internal/ghclient` package; configured via `github.token` + `github.repo`; GitHub takes precedence over GitLab when both are configured
+- **SSH agent push** — go-git `gitssh.NewSSHAgentAuth` for `git@` / `ssh://` remotes
+- **`--release-env-file` flag** — override dotenv artifact path; pass `""` to disable
+- **`git.releasable_types` config** — opt-in list of commit types that count as releasable
+- **CHANGELOG deduplication guard** — `changelog.Update()` is idempotent; skips write if section already exists
+
+## v1.3.0 — 2026-07-07
+
+### Added
+
+- **`release.env` dotenv artifact** — written on every real release containing `NEXT_VERSION=<tag>`; never committed; exposes the version to downstream GitLab CI jobs
+
+## v1.2.0 — 2026-07-07
+
+### Added
+
+- **`--verbose` flag** — prints config table, commit list with parsed types, and version decision
+- **Colored, structured CLI output** — `·` / `✓` / `!` prefix symbols; TTY-aware ANSI colors; respects `NO_COLOR` and `TERM=dumb`
+- **Name and version header** on every invocation
+
+### Changed
+
+- **Default `tag_prefix` is now empty** — bare version numbers (`1.2.3`) by default; add `tag_prefix: "v"` to opt in
+
+## v1.1.0 — 2026-07-07
+
+### Added
+
+- **CHANGELOG.md auto-update** — new dated section written on every release, grouped by commit type
+- **`--changelog-file` flag** — override changelog path
+- **`--init` flag** — scaffolds a fully-commented `.releaser.yml`

+title: CI Integration
+weight: 40
+---
+
+## GitLab CI
+
+The simplest setup uses the reusable job template shipped alongside `releaser`:
+
+```yaml
+# .gitlab-ci.yml
+include:
+  - project: releaser/releaser
+    file: .releaser.gitlab-ci.yml
+
+release:
+  extends: .releaser
+  variables:
+    GITLAB_TOKEN: $RELEASE_TOKEN   # project/group variable with api + write_repository scope
+```
+
+Or write it inline:
+
+```yaml
+release:
+  stage: release
+  image: registry.example.com/releaser:latest
+  rules:
+    - if: $CI_COMMIT_BRANCH =~ /^release\/.+$/
+  variables:
+    GITLAB_TOKEN: $RELEASE_TOKEN
+  script:
+    - releaser
+  artifacts:
+    reports:
+      dotenv: release.env          # exposes NEXT_VERSION to downstream jobs
+```
+
+### Consuming `NEXT_VERSION` downstream
+
+The `release.env` dotenv artifact exports `NEXT_VERSION=<tag>` automatically. Downstream jobs can use it:
+
+```yaml
+deploy:
+  stage: deploy
+  needs:
+    - job: release
+      artifacts: true
+  script:
+    - echo "Deploying version $NEXT_VERSION"
+```
+
+Disable the dotenv artifact (e.g. for local runs):
+
+```bash
+releaser --release-env-file ""
+```
+
+Write it to a custom path:
+
+```bash
+releaser --release-env-file deploy/version.env
+```
+
+## GitHub Actions / Gitea Actions
+
+```yaml
+name: release
+on:
+  push:
+    branches:
+      - 'release/**'
+
+jobs:
+  release:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+        with:
+          fetch-depth: 0          # full history needed for tag discovery
+
+      - name: Run releaser
+        env:
+          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+        run: |

+          chmod +x /usr/local/bin/releaser
+          releaser
+```
+
+{{< hint warning >}}
+`fetch-depth: 0` is required. A shallow clone (`--depth 1`) hides the previous tag, causing `releaser` to treat every commit as the first release.
+{{< /hint >}}
+
+## Detached HEAD
+
+In CI environments where `git checkout` leaves the repository in detached HEAD state, pass the branch name explicitly:
+
+```yaml
+script:
+  - releaser --branch "$CI_COMMIT_BRANCH"
+```
+
+## SSH push
+
+When pushing over SSH (`git@host:...` or `ssh://...` remotes), `releaser` attempts go-git SSH agent auth automatically — no extra configuration needed as long as the CI runner has an SSH agent socket available.
+
+For HTTPS remotes without a token, `releaser` delegates to the system `git` binary so credential helpers and `netrc` work as expected.

+## Environment variables
+
+| Variable | Used for |
+|----------|----------|
+| `GITLAB_TOKEN` | GitLab API auth + HTTPS push auth |
+| `CI_SERVER_URL` | GitLab instance URL |
+| `CI_PROJECT_ID` | GitLab project identifier (numeric) |
+| `CI_PROJECT_PATH` | GitLab project identifier (fallback) |
+| `GITHUB_TOKEN` | GitHub API auth |
+
+## Config sources
+
+Run `releaser --verbose --dry-run` to see every config key, its resolved value, and where it came from (`default` / `config file` / `env: VARNAME` / `flag: --name`).
+
+## `git.releasable_types`
+
+By default `fix`, `feat`, and `breaking` commits all trigger a release. Use `releasable_types` to restrict this — for example, on a maintenance branch where you want only bug fixes to release:
+
+```yaml
+git:
+  releasable_types:
+    - fix
+```
+
+## `git.bump_rules`
+
+By default every releasable commit bumps the **patch** component. The `bump_rules` map lets you promote specific types to bump **minor** instead. This is useful on a branch that manages its own minor versioning:
+
+```yaml
+git:
+  bump_rules:
+    feat: "minor"      # feat: commits bump minor, not patch
+    breaking: "minor"  # breaking changes bump minor too
+    fix: "patch"       # fix: stays patch (this is the default)
+```
+
+## Multi-module Maven
+
+`pom_paths` accepts a list and overrides `pom_path`. All listed files are updated and committed in the same release commit:
+
+```yaml
+maven:
+  pom_paths:
+    - "pom.xml"
+    - "module-a/pom.xml"
+    - "module-b/pom.xml"
+```
+
+The `--pom` CLI flag sets a single path and clears `pom_paths`.
+
+## Node.js support
+
+The `node` section is opt-in — if omitted, no `package.json` is touched. Use `package_jsons` for monorepos:
+
+```yaml
+node:
+  package_jsons:
+    - "packages/frontend/package.json"
+    - "packages/backend/package.json"
+```
+
+## Gradle support
+
+The `gradle` section is opt-in — if omitted, no build file is touched. Both Groovy DSL (`version = '1.2.3'`) and Kotlin DSL (`version = "1.2.3"`) are supported; the original quote style is preserved on write.
+
+```yaml
+gradle:
+  build_file: "build.gradle"
+```
+
+Use `build_files` for multi-module projects:
+
+```yaml
+gradle:
+  build_files:
+    - "build.gradle"
+    - "module-a/build.gradle"
+    - "module-b/build.gradle"
+```
+
+The `--gradle <path>` CLI flag sets a single build file path and clears `build_files`.
