+# How to update API docs
+
+Due to the rest handlers and related data structures are distributed in many sub-folds, currently there is no tool which can automatically extract all APIs information and generate API docs. So here we have to write APIs' docs manually.
+
+## Steps
+ 
+* Install the command line tool first.
+```
+go get github.com/rakyll/statik
+```
+* Directly Edit API docs: client/lcd/swaggerui/swagger.json
+
+* Edit API docs within this [website](https://app.swaggerhub.com). Please refer to this [link](https://app.swaggerhub.com/help/index) for how to use the about website to edit API docs.
+
+* Download swagger.json and replace the old swagger.json under client/lcd/swaggerui folds
+
+* Regenerate statik.go file
+```
+statik -src=client/lcd/swaggerui -dest=client/lcd
+```
