1. Go to the extension page:
2. Make sure the relevant settings are set:
## Standalone
In case you are using an unsupported browser, or if you have other specific needs (for example your application is in Electron), you can use the standalone application.
Install the package globally:
```bash
npm install -g @vue/devtools
```
Or locally as project dependency:
```bash
npm install --save-dev @vue/devtools
```
### Using global package
Once you installed the package globally, run:
```bash
vue-devtools
```
Then add this code to the `` section of your application HTML file:
```html
```
Or if you want to debug your device remotely:
```html
```
**(Don't forget to remove it before deploying to production!)**
`` usually looks like this: `192.168.x.x`.
Then start your development server like you are used to, *without* killing the `vue-devtools` command (for example, open a new terminal). Both need to run in parallel.
```bash
yarn dev
#or
yarn serve
```
### Using dependency package
Once you installed the package as project dependency, run:
```bash
./node_modules/.bin/vue-devtools
```
You can also use the global `vue-devtools` to start the app, but you might want to check if the local version matches the global one in this scenario to avoid any incompatibilities.
Then import it directly in your app:
```js
import devtools from '@vue/devtools'
// import Vue from 'vue'
```
> Make sure you import devtools before Vue, otherwise it might not work as expected.
And connect to host:
```js
if (process.env.NODE_ENV === 'development') {
devtools.connect(/* host, port */)
}
```
**host** - is an optional argument that tells your application where devtools middleware server is running, if you debug your app on your computer you don't have to set this (the default is `http://localhost`), but if you want to debug your app on mobile devices, you might want to pass your local IP (e.g. `http://192.168.1.12`).
**port** - is an optional argument that tells your application on what port devtools middleware server is running. If you use proxy server, you might want to set it to `null` so the port won't be added to connection URL.

## Legacy
If something is broken with the new devtools, please [submit a new issue](https://github.com/vuejs/devtools/issues/new/choose)!
Meanwhile, you can install the legacy version (v5) of the devtools:
Make sure you disable any other versions of the Vue devtools. Only one version should be enabled at a time.
