+## projectDataService
+`projectDataService` provides a way to get information about a NativeScript project.
+
+A common interface describing the results of a method is `IProjectData`:
+
+```TypeScript
+interface IProjectData extends IProjectDir {
+	projectName: string;
+	platformsDir: string;
+	projectFilePath: string;
+	projectId?: string;
+	dependencies: any;
+	devDependencies: IStringDictionary;
+	appDirectoryPath: string;
+	appResourcesDirectoryPath: string;
+	projectType: string;
+	nsConfig: INsConfig;
+	/**
+	 * Initializes project data with the given project directory. If none supplied defaults to cwd.
+	 * @param {string} projectDir Project root directory.
+	 * @returns {void}
+	 */
+	initializeProjectData(projectDir?: string): void;
+	/**
+	 * Initializes project data with the given package.json, nsconfig.json content and project directory. If none supplied defaults to cwd.
+	 * @param {string} packageJsonContent: string
+	 * @param {string} nsconfigContent: string
+	 * @param {string} projectDir Project root directory.
+	 * @returns {void}
+	 */
+	initializeProjectDataFromContent(packageJsonContent: string, nsconfigContent: string, projectDir?: string): void;
+	getAppDirectoryPath(projectDir?: string): string;
+	getAppDirectoryRelativePath(): string;
+	getAppResourcesDirectoryPath(projectDir?: string): string;
+	getAppResourcesRelativeDirectoryPath(): string;
+}
+
+interface IProjectDir {
+	projectDir: string;
+}
+
+interface INsConfig {
+	appPath?: string;
+	appResourcesPath?:string;
+}

+
+### getProjectData
+Returns an initialized IProjectData object containing data about the NativeScript project in the provided `projectDir`.
+
+* Definition:
+```TypeScript
+/**
+ * Returns an initialized IProjectData object containing data about the NativeScript project in the provided projectDir
+ * @param {string} projectDir The path to the project
+ * @returns {IProjectData} Information about the NativeScript project
+ */
+getProjectData(projectDir: string): IProjectData
+```
+
+### getProjectDataFromContent
+Returns an IProjectData object that is initialized with the provided package.json content, nsconfig.json content and `projectDir`.
+
+* Definition:
+```TypeScript
+/**
+ * Returns an initialized IProjectData object containing data about the NativeScript project in the provided projectDir
+ * @param {string} packageJsonContent The content of the project.json file in the root of the project
+ * @param {string} nsconfigContent The content of the nsconfig.json file in the root of the project
+ * @param {string} projectDir The path to the project
+ * @returns {IProjectData} Information about the NativeScript project

+getProjectDataFromContent(packageJsonContent: string, nsconfigContent: string, projectDir?: string): IProjectData
+```

 ## extensibilityService
 `extensibilityService` module gives access to methods for working with CLI's extensions - list, install, uninstall, load them. The extensions add new functionality to CLI, so once an extension is loaded, all methods added to it's public API are accessible directly through CLI when it is used as a library. Extensions may also add new commands, so they are accessible through command line when using NativeScript CLI.
