-# grails-spring-restdocs-example
-Example of using Spring REST Docs with Grails
+# rest-notes-grails
+
+## Overview
+
+This is a sample project using Grails 3, Spock, and Spring REST docs. For more
+information about the Grails framework please see [grails.org](http://grails.org).
+
+Grails is built on top of Spring Boot and Gradle so there are a few different ways to
+run this project including:
+
+### Gradle Wrapper (recommended)
+
+The gradle wrapper allows a project to build without having Gradle installed locally. The
+executable file will acquire the version of Gradle and other dependencies recommended for
+this project. This is especially important since some versions of Gradle may cause
+conflicts with this project.
+
+On Unix-like platforms, such as Linux and Mac OS X:
+
+```
+$ ./gradlew run
+```
+
+On Windows:
+
+```
+$ gradlew run
+```
+
+*Please note*, if you are including integration tests in Grails, they will not run as
+part of the `gradle test` task.  Run them via the build task or individually as
+`gradle integrationTest`
+
+### Gradle Command Line
+
+Clean the project:
+
+```
+$ gradle clean
+```
+
+Build the project:
+
+```
+$ gradle build
+```
+
+Run the project:
+
+```
+$ gradle run
+```
+
+### Grails Command Line
+
+Grails applications also have a command line feature useful for code generation and
+running projects locally. The  command line is accessible by typing `grails` in the
+terminal at the root of the project.  Please ensure you are running  the correct version
+of Grails as specified in [gradle.properties](gradle.properties)
+
+Similar to `gradle clean`, this task destroys the `build` directory and cached assets.
+
+```
+grails> clean
+```
+
+The 'test-app' task runs all of the tests for the project.
+
+```
+grails> test-app
+```
+
+The `run-app` task is used to run the application locally.  By default, the project is
+run in development mode including  automatic reloading and not caching static assets. It
+is not suggested to use this in production.
+
+```
+grails> run-app
+```
+
+### Building and Viewing the Docs
+
+This is an example of the Grails API profile.  Therefore, there is no view layer to
+return the docs as static assets.  The result of running `asciidoctor` or `build` is that
+the docs are sent to `/build/asciidoc/`.  You can then publish them to a destination of
+your choosing using the  [gradle github-pages](https://github.com/ajoberstar/gradle-git)
+plugin or similar.
+
+To just generate documentation and not run the application use:
+
+```
+$ ./gradlew asciidoctor
+```
