# use

## Description

* Switch to (or activate) a specified platform version

## Syntax

`ern platform use <version>`

**Arguments**

`<version>`

* The Electrode Native platform version to activate.
* Sample values : `v0.18.0` / `0.18.0` / `latest`
* Using `latest` will switch to the latest version of Electrode Native

## Remarks

* If the target platform version is not installed locally, the `ern platform use <version>` command runs the [ern platform install](https://native.electrode.io/v0.43/cli-commands/platform/install) command, which installs the version—before switching to the specified version.
