 # Changelog

 All notable changes to this project will be documented in this file.
 
 The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
 and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
 
-## [Unreleased]
+## 6.0.0
+
+- Make `elm-verify-examples.json` optional [#110](https://github.com/stoeffel/elm-verify-examples/pull/110)
+
+  - Run elm-verify-examples on all elm files in source directory by default.
+
+  - Add option `all` to `elm-verify-examples.json` to verify all elm files.
+
+    ```diff
+    + "tests": "all"
+    ```
+
+  - Remove `root` from elm-verify-examples.json. In addition it will respect source-directories defined in elm.json
+
+    To migrate, remove the "root" key in your config file and move it into `/tests`.
+
+    ```diff
+    - "root": "../src",
+    ```
+
+## 5.3.0
 
 - Do not run tests by default, only generate [#65](https://github.com/stoeffel/elm-verify-examples/issues/65)
 - Add --run-tests (-r) option to run generated tests [#65](https://github.com/stoeffel/elm-verify-examples/issues/65)
 
-
 ## 2.0.0
 
 - We have a changelog now :tada:

 ## Setup
 
+There is no need for any configuration. elm-verify-examples will run on all elm files in the specified `source-directories` (`elm.json`). It's possible to create a config file if you want to run it on only a subset of files or on additional markdown files.

 ```bash
 $ touch tests/elm-verify-examples.json
 ```

 }

+Alternatively you can run elm-verify-examples on all elm files in your source directories:
+
+```json
+{
+  "tests": "all"
+}
+```
+
+or
+
+```json
+{
+  "tests": ["all", "Some.md"]
+}
+```
+
 It's recommended to add `./tests/VerifyExamples` to your `.gitignore`.
 
 If you are building a _package_, you can pass the string `"exposed"` instead of an explicit list of modules,
