 ------------------
 
 To use a mirror of the node binaries, set `$NVMW_NODEJS_ORG_MIRROR`.
 
 e.g.: In China, you use this mirror:
 
 ```bash
-set "NVMW_NODEJS_ORG_MIRROR=http://dist.u.qiniudn.com"
-nvmw install 0.11.12
+set "NVMW_NODEJS_ORG_MIRROR=http://npm.taobao.org/mirrors/node"
+set "NVMW_IOJS_ORG_MIRROR=http://npm.taobao.org/mirrors/iojs"
+
+nvmw install 0.11.14
+nvmw install node/v0.11.15
+nvmw install iojs/v1.0.2
+nvmw install iojs/latest
