# Markdown Architectural Decision Records



> "Markdown Architectural Decision Records" (MADR) `[ˈmæɾɚ]` – decisions that [matter `[ˈmæɾɚ]`](https://en.wiktionary.org/wiki/matter#Pronunciation).



For user documentation, please head to .



## Quick start



* [`adr-template.md`](template/adr-template.md) has all sections, with explanations about them.

* [`adr-template-minmal.md`](template/adr-template-minimal.md) only contains mandatory sections, with explanations about them. 

* [`adr-template-bare.md`](template/adr-template-bare.md) has all sections, which are empty (no explanations).

* [`adr-template-bare-minimal.md`](template/adr-template-bare-minimal.md) has the mandatory sections, without explanations. 



Copy it into `docs/decisions`.

For each ADR, copy the template to `nnnn-title.md` and adapt.

Longer explanation: Head to .



## Development hints



* MADR follows [Semantic Versioning 2.0.0](https://semver.org/) and documents changes in a `CHANGELOG.md` following [keep a changelog 1.0.0](http://keepachangelog.com/en/1.0.0/).

* Issues can be reported at .

* Suggestions can be contributed via pull requests. MADR offers pre-configured VS Code web environment at [Gitpod](https://gitpod.io/#https://github.com/adr/madr).

* MADR uses [markdownlint](https://github.com/DavidAnson/markdownlint) as Linter for Markdown files. Use [markdownlint](https://marketplace.visualstudio.com/items?itemName=DavidAnson.vscode-markdownlint) for checking for linting issues in VS Code.

* `template/adr-template.md` is mirrored to `docs/decisions/adr-template`.

  However, following YAML front matter is added to make it handled properly by the [Just the Docs Jekyll Template](https://just-the-docs.github.io/just-the-docs/). 

  ```markdown

  parent: Decisions

  nav_order: 100

## How to start Jekyll locally



For rendering the `docs` directory, Jekyll is needed.



For local development, follow the [Jekyll installation instructions](https://jekyllrb.com/docs/installation/).

Installing the latest version of ruby followed by `gem install bundler` should be enough.



Afterwards, run



```terminal

bundle install

jekyll serve --livereload

```



and go to  in your browser.



On Windows, using a dockerized environment is recommended:



```terminal

docker run -p 4000:4000 --rm -v "C:\git-repositories\adr.github.io\madr\docs":/site bretfisher/jekyll-serve

```



In case you get errors regarding `Gemfile.lock`, just delete `Gemfile.lock` and rerun.



## Updating just-the-docs



* Adapt `docs/Gemfile` to use newer just-the-docs version. Thereby check  for versions.

* Delete `docs/Gemfile.lock`. Start `bundle install`.

* Check .

* Check .



## Releasing a new version



1. Update the examples at `docs/index.md` and `docs/examples.md`.

2. Update the concrete decisions in `docs/decisions/*` with the new template.

3. Commit ("Update examples and decisions") and push. Possibly as pull request.

4. Adapt the version reference in `template/0000-use-markdown-architectural-decision-records.md`.

5. Update "template" files in `docs/decisions`:

   * Copy `template/0000-use-markdown-architectural-decision-records.md` to `docs/decisions/0000-use-markdown-architectural-decision-records.md`.

   * Adapt content of `docs/decisions/adr-template.md` based on `template/adr-template.md`.

     Thereby, ensure that the YAML front matter in `docs/decisions/adr-template.md` is kept.

6. Add link to `docs/index.md` at "Older versions" (for the homepage).

7. Copy `.markdownlint.yml` to `template/.markdownlint.yml` (and possibly to `docs/.markdownlint.yml`).

8. Update `CHANGELOG.md`.

9. Commit.

10. Update `package.json` and publish to [npmjs](https://www.npmjs.com/package/madr) using [release-it](https://www.npmjs.com/package/release-it) (do not create a release on GitHub). This also does a commit.

11. Create GitHub release using [github-release-from-changelog](https://www.npmjs.com/package/github-release-from-changelog).

12. Merge `develop` into `gh-pages`
