+swagger-codegen-maven-plugin
+============================
+
+A Maven plugin to support the [swagger](http://swagger.io) code generation project
+
+Usage
+============================
+
+Add to your `build->plugins` section (default phase is `generate-sources` phase)
+```xml
+<plugin>
+    <groupId>io.swagger</groupId>
+    <artifactId>swagger-codegen-maven-plugin</artifactId>
+    <version>${project.version}</version>
+    <executions>
+        <execution>
+            <goals>
+                <goal>generate</goal>
+            </goals>
+            <configuration>
+                <inputSpec>src/main/resources/api.yaml</inputSpec>
+                <language>java</language>
+                <configOptions>
+                   <sourceFolder>src/gen/java/main</sourceFolder>
+                </configOptions>
+            </configuration>
+        </execution>
+    </executions>
+</plugin>
+```
+
+Followed by:
+
+```
+mvn clean compile
+```
+
+### General Configuration parameters
+
+- `inputSpec` - swagger spec file path
+- `language` - target generation language
+- `output` - target output path (default is `${project.build.directory}/generated-sources/swagger`)
+- `templateDirectory` - directory with mustache templates
+- `addCompileSourceRoot` - add the output directory to the project as a source root (`true` by default)
+- `modelPackage` - the package to use for generated model objects/classes
+- `apiPackage` - the package to use for generated api objects/classes
+- `invokerPackage` - the package to use for the generated invoker objects
+- `configOptions` - a map of language-specific parameters (see below)
+
+### Java-specific parameters (under configOptions)
+
+- `sourceFolder` - the folder to use for generated sources under the output folder
+- `groupId` - groupId in generated pom.xml
+- `artifactId` - artifactId in generated pom.xml
+- `artifactVersion` - artifact version in generated pom.xml
