+
+Gradle plugin that lets you visualize your dependencies in a graph.
+
+# Set up
+
+```groovy
+buildscript {
+  repositories {
+    mavenCentral()
+  }
+  dependencies {
+    classpath "com.vanniktech:gradle-dependency-graph-generator-plugin:0.1.0"
+  }
+}
+
+apply plugin: "com.vanniktech.dependency.graph.generator"
+```
+
+Note that this plugin can be applied at the root of the project or at a specific project. Both cases will just work.
+
+This plugin is using the `dot` command line tool for generating the graphs hence you need to install it. Mac users can use `brew install graphviz`. Ubuntu users can `sudo apt-get install graphviz`.
+
+Information: [This plugin is also available on Gradle plugins](https://plugins.gradle.org/plugin/com.vanniktech.dependency.graph.generator)
+
+### Snapshots
+
+Can be found [here](https://oss.sonatype.org/#nexus-search;quick~gradle-dependency-graph-generator-plugin). Current one is:
+
+```groovy
+classpath "com.vanniktech:gradle-dependency-graph-generator-plugin:0.2.0-SNAPSHOT"
+```
+
+## Usage
+
+By default this plugin will generate a `generateDependencyGraph` task that can be used to generate a dependency graph that could look like this. This graph was generated from my [chess clock app](https://play.google.com/store/apps/details?id=com.vanniktech.chessclock).
+
+![Example graph.](example.png)
+
+There are extension points to be able to generate graphs which only include some dependencies and their transitive ones. The trick is to hook a [Generator](./src/main/kotlin/com/vanniktech/dependency/graph/generator/DependencyGraphGeneratorExtension.kt) in over the `dependencyGraphGenerator` extension. Note that this is extremely experimental and will likely change between releases. It's still fun though.
+
+### Generator Example
+
+We only want to show which Firebase libraries we're using and give them the typical Firebase orange.
+
+```groovy
+import com.vanniktech.dependency.graph.generator.DependencyGraphGeneratorPlugin
+import com.vanniktech.dependency.graph.generator.DependencyGraphGeneratorExtension.Generator
+import com.vanniktech.dependency.graph.generator.dot.GraphFormattingOptions
+import com.vanniktech.dependency.graph.generator.dot.Color
+import com.vanniktech.dependency.graph.generator.dot.Shape
+import com.vanniktech.dependency.graph.generator.dot.Style
+
+plugins.apply(DependencyGraphGeneratorPlugin)
+
+def firebaseGenerator = new Generator(
+  "firebaseLibraries", // Suffix for our Gradle task.
+  "", // Root suffix that we don't want in this case.
+  { dependency -> dependency.getModuleGroup().startsWith("com.google.firebase") }, // Only want Firebase.
+  { dependency -> true }, // Include transitive dependencies.
+  { dependency -> new GraphFormattingOptions(Shape.BOX, Style.FILLED, Color.fromRgb(255, 203, 43)) }, // Give them some color.
+)
+
+dependencyGraphGenerator {
+  generators = [ firebaseGenerator ]
+}
+```
+
+This will generate a new task `generateDependencyGraphFirebaseLibraries` which when run will yield this graph:
+
+![Example Firebase graph.](example-firebase.png)
+
+Note that when using the `dependencyGraphGenerator` extension with custom generators you loose the default one, to add it back simply use the `Generator.ALL` instance:
+
+```groovy
+dependencyGraphGenerator {
+  generators = [ Generator.ALL, firebaseGenerator ]
+}
+```
