+Can you ever image build a gui application like play Lego blocks? kivyblocks just try to provide programmer a tool to build a application like play lego blocks
+
+kivyblocks base on the python package 'kivy', which is a cross platform GUI package and can play on window, linux, mac OS x, android and iphone
 
 ## Requirement
+
+[appPublic](https://github.com/yumoqing/appPublic)
+[kivycalendar](https://github.com/yumoqing/kivycalendar)
+[kivy](https://github.com/kivy/kivy)
+...
 see the [requirements.txt]('./requirements.txt')
 
 ## Principle
 
-There is a blocksapp(inherited from App) contains a toppage widget to hold all the top widget create by Blocks, and the Blocks can create widgets which is specified in a dictionary data, and a HttpClient to get data or weiget spec file for web server.
+There is a BlocksApp(inherited from App) in kivyblocks contains a all widgets can be created by Blocks, and the Blocks creates widgets according a customized json data, the data can download from application server or local filesystem. 
+The Customized json data has it own format to descript the UI and it's interaction. please see the "Customized json data" section for further information.
 
-the widget specifiction file  
+## installation
+```
+pip install git+https://github.com/yumoqing/kivy-blocks
+```
+Use above command to install the newest version of kivyblocks
+the widget specification file  
 ## How to use
 see the simple example below:
 ```
-```
+import sys
+import os
+from appPublic.folderUtils import ProgramPath
+from appPublic.jsonConfig import getConfig
+
+from kivyblocks.blocksapp import BlocksApp
+from kivyblocks.blocks import Blocks
+
+class TestApp(BlocksApp):
+	def build(self):
+		b = super(TestApp, self).build()
+		widget_desc = {
+			"widgettype":"VBox",
+			"options":{},
+			"subwidgets":[
+				{
+					"widgettype":"Title1",
+					"options":{
+						"text":"Say Hello",
+						"i18n":True,
+						"size_hint_y":None,
+						"height":"py::CSize(2)"
+					}
+				},
+				{
+					"widgettype":"Text",
+					"options":{
+						"text":"Hello KivyBlocks"
+					}
+				}
+			]
+		}
+		blocks = Blocks()
+		x = blocks.widgetBuild(widget_desc)
+		return x
+
+
+if __name__ == '__main__':
+	pp = ProgramPath()
+	workdir = pp
+	if len(sys.argv) > 1:
+		workdir = sys.argv[1]
+	print('ProgramPath=',pp,'workdir=',workdir)
+
+	config = getConfig(workdir,NS={'workdir':workdir,'ProgramPath':pp})
+	myapp = TestApp()
+	myapp.run()
+```
+if you running it on window, it will show the following:

+# Blocks
+Blocks是kivyblocks的核心类，负责将字典类型的数据转化为GUI的Widget。
+Blocks也注册到了kivy.factory.Factory中，可以使用
+```
+blocks = Factory.Blocks()
+```
+初始化实例
+
+## 方法
+### widgetBuild(desc)
+#### 参数
+* desc 	1) 字典类型， Widget描述的字典数据
+		2) 字符串，可通过json导入的字符串
+
+#### 返回值
+成功返回创建的widget实例 
+失败返回空
+
+#### 事件
+如果创建widget成功，触发”on_built"事件，
+如果创建widget失败，将触发“on_failed”事件
+
+事件处理函数的例子如下：
+创建成功：
+```
+def on_built(o, w):
+	pass
+```
+其中，o为Blocks实例， w为新建widget的实例
+创建失败
+```
+def on_failed(o,e):
+	pass
+```
+其中， o为Blocks实例， e为例外实例
+
+#### 功能描述
+此方法按照desc字典数据构建一个Widget，首先按照desc['options']中的参数初始化“widgettype”属性指定的类，并将“subwidgets”中的子Widget创建，并添加到Widget中，并且将非“options”，“subwidgets“和”binds“的其他属性也创建完成，并作为Widget的属性变量，最后创建”binds“中的事件处理。
+
+widgetBuild按照执行结果的状态，会触发两个事件中的一个，如果创建成功，会触发"on_built"
+
+### getWidgetById(id, from_widget=None)
+查找指定id的widget，可以指定从整个widget树上的哪个节点开始查找。
+#### 参数
+id：字符串，其中‘.'用于分割，节点id，如果id中存在‘.'，那么
