 Examples
 --------
 
+1. Create new project in the current working directory
+
 .. code-block:: bash
 
-    # Change directory to the future project
-    $ cd /path/to/empty/directory
     $ platformio init
-    Project has been initialized!
-    Please put your source code to `src` directory, external libraries to `lib`
-    and setup environments in `platformio.ini` file.
-    Then process project with `platformio run` command.
+    The current working directory *** will be used for the new project.
+    You can specify another project directory via
+    `platformio init -d %PATH_TO_PROJECT_DIR%` command.
+
+    The next files/directories will be created in ***
+    platformio.ini - Project Configuration File
+    src - a source directory. Put your source code here
+    lib - a directory for the project specific libraries
+    Do you want to continue? [y/N]: y
+    Project has been successfully initialized!
+    Now you can process it with `platformio run` command.
+
+
+2. Create new project in the specified directory
+
+.. code-block:: bash
+
+    $ platformio init -d %PATH_TO_DIR%
+    The next files/directories will be created in ***
+    platformio.ini - Project Configuration File
