+i18n
+====
+
+Package i18n is for app Internationalization and Localization.
+
+## Introduction
+
+This package provides multiple-language options to improve user experience. Sites like [Go Walker](http://gowalker.org) and [gogs.io](http://gogs.io) are using this module to implement Chinese and English user interfaces.
+
+You can use following command to install this module:
+
+    go get github.com/Unknwon/i18n
+
+## Usage
+
+First of all, you have to import this package:
+
+```go
+import "github.com/Unknwon/i18n"
+```
+
+The format of locale files is very like INI format configuration file, which is basically key-value pairs. But this module has some improvements. Every language corresponding to a locale file, for example, under `conf/locale` folder of [gogsweb](https://github.com/gogits/gogsweb/tree/master/conf/locale), there are two files called `locale_en-US.ini` and `locale_zh-CN.ini`.
+
+The name and extensions of locale files can be anything, but we strongly recommend you to follow the style of gogsweb.
+
+## Minimal example
+
+Here are two simplest locale file examples:
+
+File `locale_en-US.ini`:
+
+```ini
+hi = hello, %s
+bye = goodbye
+```
+
+File `locale_zh-CN.ini`:
+
+```ini
+hi = 您好，%s
+bye = 再见
+```
+
+### Do Translation
+
+There are two ways to do translation depends on which way is the best fit for your application or framework.
+
+Directly use package function to translate:
+
+```go
+i18n.Tr("en-US", "hi", "Unknwon")
+i18n.Tr("en-US", "bye")
+```
+
+Or create a struct and embed it:
+
+```go
+type MyController struct{
+    // ...other fields
+    i18n.Locale
+}
+
+//...
+
+func ... {
+    c := &MyController{
+        Locale: i18n.Locale{"en-US"},
+    }
+    _ = c.Tr("hi", "Unknwon")
+    _ = c.Tr("bye")
+}
+```
+
+Code above will produce correspondingly:
+
+- English `en-US`：`hello, Unknwon`, `goodbye`
+- Chinese `zh-CN`：`您好，Unknwon`, `再见`
+
+## Section
+
+For different pages, one key may map to different values. Therefore, i18n module also uses the section feature of INI format configuration to achieve section.
+
+For example, the key name is `about`, and we want to show `About` in the home page and `About Us` in about page. Then you can do following:
+
+Content in locale file:
+
+```ini
+about = About
+
+[about]
+about = About Us
+```
+
+Get `about` in home page:
+
+```go
+i18n.Tr("en-US", "about")
+```
+
+Get `about` in about page:
+
+```go
+i18n.Tr("en-US", "about.about")
+```
+
+### Ambiguity
+
+Because dot `.` is sign of section in both [INI parser](https://github.com/go-ini/ini) and locale files, so when your key name contains `.` will cause ambiguity. At this point, you just need to add one more `.` in front of the key.
+
+For example, the key name is `about.`, then we can use:
+
+```go
+i18n.Tr("en-US", ".about.")
+```
+
+to get expect result.
+
+## Helper tool
+
+Module i18n provides a command line helper tool beei18n for simplify steps of your development. You can install it as follows:
+
+	go get github.com/Unknwon/i18n/ui18n
+
+### Sync locale files
+
+Command `sync` allows you use a exist local file as the template to create or sync other locale files:
+
+	ui18n sync srouce_file.ini other1.ini other2.ini
+
+This command can operate 1 or more files in one command.
+
+## More information
+
+If the key does not exist, then i18n will return the key string to caller. For instance, when key name is `hi` and it does not exist in locale file, simply return `hi` as output.
