+# What are plugins? 
 
+## Code ran before a command to modify output.
+
+
+sern has a bunch of premade plugins thanks to our awesome community, which you can install via the cli!
+
+
+```sh
+sern plugins
+```
+Run this to see all community plugins.
+
+Lets make a command only meant to be run in a *nsfw channel!*
+
+- Install the nsfwOnly plugin.
+- Thank the creator of the plugin. (Thank you)
+- Read the doucmentation that comes with it.
+- Use it!
+```ts 
+export default commandModule({ 
+    type: CommandType.Slash,
+    description: "post very nsfw stuff",
+    //WE CALL THE PLUGIN IN THE PLUGINS FIELD.
+    plugins: [nsfwOnly("You cannot use this command here.", true)]
+})
+
+```
+Keep in mind some plugins cannot run for every type of interaction sern handles.
+For example, nsfwOnly plugin will probably not work in a modal.
+
+To create custom plugins, view [here](../../../guide/walkthrough/plugins).
+
+## Moving forward:
+Download the `channelType` plugin, because we'll be using that for this tutorial.
