+### 怎么加入
+
+```
+# 先 fork 此项目
+# checkout 自己的项目后操作：
+$ git remote -v # 查看主机源，如果只有自己的 origin 那还没有设置 upstream
+$ git remote add upstream https://github.com/omniaccountcorp/reapal
+$ git fetch upstream
+$ git checkout master
+$ git merge --no-ff upstream/master
+# 如果有冲突解决...
+$ git add 修改的文件
+$ git commit -m 'merge from origin-git'
+$ git push origin [自己开发的分支]
+```
+
+### 开发新 api 指南
+1. 根据 service 名字，确定好 module ，新 api 文件名，方法名，比如：
+    ``` ruby
+    # 假如服务名: reapal.trust.mobileModify
+    # 文件名：lib/reapal/api/trust/mobile_modify.rb
+    module Reapal
+      module Api
+        module MobileModify
+          def mobile_modify(...)
+             # ...
+          end
+        end
+      end
+    end
+    
+    ```
+2. 新 api 文件中写好注释（记得标明是文档中的哪一节），确定好函数输入输出
+3. 写 spec
+4. 实现 api
+5. 测试通过后向作者提交 spec
 
 After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
 
 To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
