Contributing developers upgrade modules and extensions by specifying their versions in the Adobe Commerce or Magento Open Source composer.json file. If you are not a contributing developer, see Perform an upgrade.

You can either add a require section to the composer.json file or you can use the composer require command as follows:

Log in to your server.
Switch to the file system owner.
Change to the directory where you cloned the application. For example,
```
cd /var/www/magento2
```

You have the following options:

Get available module versions

Command usage:

composer show --all <vendor>/<name>

For example:

composer show --all example/module

Use the `composer require` command

Command usage:

composer require <vendor>/<name>:<version>

For example:

composer require example/module:1.0.0

Wait while Composer updates dependencies and installs the module.

Add a `require` section to the composer.json file

Open the composer.json in a text editor.

Add a require section.

"require": {
  "<vendor>/<name>": "<version>",
  "<vendor>/<name>": "<version>"
}

Save your changes to the composer.json file and exit the text editor.
Resolve dependencies and write exact versions to the composer.lock file.
```
composer update
```
