+
+                        ## Howto
+
+                        1. Open the project.apj file with AntOSDK (simply double Click on it)
+                        2. Modify the UI in *assets/scheme.html*
+                        3. Modify application code in *coffees/main.coffee*
+                        4. Modify CSS style in *css/main.css*
+                        5. Other files need to be copied: put in to assets
+
+                        ## Set up build target
+
+                        Click **Menu> Build > Build Option** or simply hit **ALT-Y**
+
+                        In the build options dialog, add or remove files that need to be
+                        included into the build
+
+                        Click **Save**
+
+                        ## Build application
+                        * To build: **Menu > Build > Build** or **ALT-C**
+                        * To build and run: **Menu > Build > Build and Run** or **CTRL-R**
