To add a custom namespace to the autoloader you need to define an alias for the base directory of the namespace using [[Yii::setAlias()]].
For example to load classes in the `foo` namespace that are located in the `path/to/foo` directory you will call `Yii::setAlias('@foo', 'path/to/foo')`.

In this guide all composer commands assume you have installed composer [globally](https://getcomposer.org/doc/00-intro.md#globally)
so that it is available as the `composer` command. If you are using the `composer.phar` in the local directory instead,
you have to adjust the example commands accordingly.
If you had Composer already installed before, make sure you use an up to date version. You can update Composer
by running `composer self-update`.
> Note: During the installation of Yii, Composer will need to request a lot of information from the Github API.
> The number of requests depends on the number of dependencies your application has and may be bigger than the
> **Github API rate limit**. If you hit this limit, Composer may ask for your Github login credentials to obtain
> a Github API access token. On fast connections you may hit this limit earlier than Composer can handle so we
> recommend to configure the access token before installing Yii.
> Please refer to the [Composer documentation about Github API tokens](https://getcomposer.org/doc/articles/troubleshooting.md#api-rate-limit-and-oauth-tokens)
Yii relies on [Bower](http://bower.io/) and/or [NPM](https://www.npmjs.org/) packages for the asset (CSS and JavaScript) libraries installation.
It uses Composer to obtain these libraries, allowing PHP and CSS/JavaScript package versions to resolve at the same time.
This can be achieved either by usage of [asset-packagist.org](https://asset-packagist.org) or [composer asset plugin](https://github.com/francoispluchino/composer-asset-plugin/).
Please refer to [Assets documentation](structure-assets.md) for more details.
You may want to either manage your assets via native Bower/NPM client, use CDN or avoid assets installation entirely.
In order to prevent assets installation via Composer, add the following lines to your 'composer.json':
```json
"replace": {
"bower-asset/jquery": ">=1.11.0",
"bower-asset/inputmask": ">=3.2.0",
"bower-asset/punycode": ">=1.3.0",
"bower-asset/yii2-pjax": ">=2.0.0"
},
```
> Note: in case of bypassing asset installation via Composer, you are responsible for the assets installation and resolving
> version collisions. Be prepared for possible inconsistencies among asset files from different extensions.
