 ## How To Start
 
+You have 2 different alternatives: Using our [Packagist project](https://packagist.org/packages/codelytv/php-bootstrap) with Composer, or manually cloning [this repo](https://github.com/CodelyTV/php-bootstrap/):
+
+### Using Composer
+
+Start completely from scratch without having to delete this bootstrap project Git history:
+
 1. If you don't have it already, [install Composer](https://getcomposer.org/download/).
-2. Create your project based on this bootstrap repo: `composer create-project codelytv/php-bootstrap your-kata-name`.
-3. Run all the checks: `composer test`. This will do some checks that you can perform with isolated commands: 
+2. Create your project based on the [Packagist project](https://packagist.org/packages/codelytv/php-bootstrap). This will also download the project dependencies: `composer create-project codelytv/php-bootstrap your-project-name`.
+3. Move to the project directory: `cd your-project-name`
+4. Run all the checks: `composer test`. This will do some checks that you can perform with isolated commands: 
+    1. [PHP Parallel Lint](https://github.com/JakubOnderka/PHP-Parallel-Lint): `composer lint`.
+    2. [PHP Style Check](https://github.com/squizlabs/PHP_CodeSniffer): `composer style`. If you want to fix style issues automatically: `composer fix-style`.
+    3. [PHP Unit](https://phpunit.de/): `composer phpunit`.
+5. Create your own repository:
+    1. Initialize your own Git repository: `git init`
+    2. Add the bootstrap files: `git add .`
+    3. Commit: `git commit -m "Initial commit with project boilerplate based on https://github.com/CodelyTV/php-bootstrap"`
+    4. Add your remote repository: `git remote add origin [email protected]:your-username/your-project-name`
+    5. Upload your local commits to the new remote repo: `git push -u origin master`
+6. Start coding! 
+
+### Cloning the repository 
+
+Just in case you prefer to avoid dealing with `composer create-project`, you can also clone this repository. We recommend to follow the next step by step process in order to avoid adding the bootstrap project commits to your project Git history:
+
+1. Clone this repository: `git clone https://github.com/CodelyTV/php-bootstrap your-project-name`
+2. Move to the project directory: `cd your-project-name`
+3. If you don't have it already, [install Composer](https://getcomposer.org/download/).
+4. Install the project dependencies: `composer install`
+5. Run all the checks: `composer test`. This will do some checks that you can perform with isolated commands: 
     1. [PHP Parallel Lint](https://github.com/JakubOnderka/PHP-Parallel-Lint): `composer lint`.
     2. [PHP Style Check](https://github.com/squizlabs/PHP_CodeSniffer): `composer style`. If you want to fix style issues automatically: `composer fix-style`.
     3. [PHP Unit](https://phpunit.de/): `composer phpunit`.

+6. Create your own repository cleaning the bootstrap project history:
+    1. Remove previous Git history in order to do not add the bootstrap repo noise in your project: `rm -rf .git`
+    2. Initialize your own Git repository: `git init`
+    3. Add the bootstrap files: `git add .`
+    4. Commit: `git commit -m "Initial commit with project boilerplate based on https://github.com/CodelyTV/php-bootstrap"`
+    5. Add your remote repository: `git remote add origin [email protected]:your-username/your-project-name`
+    6. Upload your local commits to the new remote repo: `git push -u origin master`
