-#### 介绍
-Implementation of Bitcoin BIP-0039
+Reference implementation of BIP-0039: Mnemonic code for generating
+deterministic keys
 
-#### 软件架构
-软件架构说明
+Abstract
+--------
 
+This BIP describes the implementation of a mnemonic code or mnemonic sentence --
+a group of easy to remember words -- for the generation of deterministic wallets.
 
-#### 安装教程
+It consists of two parts: generating the mnenomic, and converting it into a
+binary seed. This seed can be later used to generate deterministic wallets using
+BIP-0032 or similar methods.

+   from mnemonic import Mnemonic
+
+Initialize class instance, picking from available dictionaries:
+
+- english
+- chinese_simplified
+- chinese_traditional
+- french
+- italian
+- japanese
+- korean 
+- spanish
+
+
+   mnemo = Mnemonic(language)
+   mnemo = Mnemonic("english")
+
+Generate word list given the strength (128 - 256):
+
+   words = mnemo.generate(strength=256)
+  
+Given the word list and custom passphrase (empty in example), generate seed:
+
+   seed = mnemo.to_seed(words, passphrase="") 
+
+Given the word list, calculate original entropy:
+
+   entropy = mnemo.to_entropy(words)
