# Installation

## Composer Installation

The only thing you have to do is to run this command, and you're ready to go.

```console
composer require codeigniter4/tasks
```

#### A composer error occurred?

If you get the following error:

```console
Could not find a version of package codeigniter4/tasks matching your minimum-stability (stable).
Require it with an explicit version constraint allowing its desired stability.
```

1. Run the following commands to change your [minimum-stability](https://getcomposer.org/doc/articles/versions.md#minimum-stability) in your project `composer.json`:

    ```console
    composer config minimum-stability dev
    composer config prefer-stable true
    ```

2. Or specify an explicit version:

    ```console
    composer require codeigniter4/tasks:dev-develop
    ```

   The above specifies `develop` branch.
   See <https://getcomposer.org/doc/articles/versions.md#branches>

## Manual Installation

In the example below we will assume, that files from this project will be located in `app/ThirdParty/tasks` directory.

Download this project and then enable it by editing the `app/Config/Autoload.php` file and adding the `CodeIgniter\Tasks` namespace to the `$psr4` array. You also have to add a companion project [Settings](https://github.com/codeigniter4/settings) in the same fashion, like in the below example:

```php
<?php

// ...

public $psr4 = [
    APP_NAMESPACE => APPPATH, // For custom app namespace
    'Config'      => APPPATH . 'Config',
    'CodeIgniter\Settings' => APPPATH . 'ThirdParty/settings/src',
    'CodeIgniter\Tasks'    => APPPATH . 'ThirdParty/tasks/src',
];

// ...

```

## Database Migration

Regardless of which installation method you chose, we also need to migrate the database to add new tables.

You can do this with the following command:

#### for Unix
```console
php spark migrate -n CodeIgniter\\Settings
```

#### for Windows
```console
php spark migrate -n CodeIgniter\Settings
```
