title: Using a different Node.js version

Now that you've got Node.js setup, we can start setting up the FreeSewing
development environment.
But before doing so, let's look at how `nvm` can help you juggle different
Node.js versions.
### nvm ls
To see the different Node.js versions on your system, run this command:
```bash
nvm ls
```
It will show you a list of local Node.js versions,
either the version number or an _alias_ that points to a specific version.
You should see the `lts/*` alias in the list which is what we've just installed.
### nvm ls-remote
To see all Node.js versions that are available, not just those you have locally,
run this command:
```bash
nvm ls-remote
```
It will spit out a long list of Node.js versions that you can install.
### nvm install
For any of these versions, either local or remote, you can install them
by making a note of the version or alias and running this command:
```bash
nvm install <version-or-alias>
```
### nvm use
With multiple Node.js versions installed, `nvm` allows you to switch between different
versions. Just tell it which version you want to use:
```bash
nvm use lts/iron
```
If you picked a version that is not installed, `nvm` will simply tell you
and even suggest the command you should type to install it. Handy!
