# Using a plugin
You can use a plugin by simply installing it using npm
.
npm i @chitchatjs/plugin-ax-common
and then, importing it into the state where you want to add that experience in your skill.
import { common } from "@chitchatjs/plugin-ax-common";
let state1 = ax
.state()
.block(
ax
.compound()
.add(ax.say("This is plugin usage example"))
.add(common.defaultHandlers()) // from common plugin
.build()
)
.build();
