+# GildedRose Kata - PHP Version
+
+See the [top level readme](../README.md) for general information about this exercise. This is the PHP version of the
+ GildedRose Kata. 
+
+## Installation
+
+The kata uses:
+
+- PHP 7.2+
+- [Composer](https://getcomposer.org)
+
+Recommended:
+- [Git](https://git-scm.com/downloads)
+
+Clone the repository
+
+```sh
+git clone git@github.com:emilybache/GildedRose-Refactoring-Kata.git
+```
+
+or
+
+```shell script
+git clone https://github.com/emilybache/GildedRose-Refactoring-Kata.git
+```
+
+Install all the dependencies using composer
+
+```shell script
+cd ./GildedRose-Refactoring-Kata/php
+composer install
+```
+
+## Dependencies
+
+The project uses composer to install:
+
+- [PHPUnit](https://phpunit.de/)
+- [ApprovalTests.PHP](https://github.com/approvals/ApprovalTests.php)
+- [PHPStan](https://github.com/phpstan/phpstan)
+- [Easy Coding Standard (ECS)](https://github.com/symplify/easy-coding-standard) 
+- [PHP CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer/wiki)
+
+## Folders
+
+- `src` - contains the two classes:
+  - `Item.php` - this class should not be changed.
+  - `GildedRose.php` - this class needs to be refactored, and the new feature added.
+- `tests` - contains the tests
+  - `GildedRoseTest.php` - Starter test.
+  - `ApprovalTest.php` - alternative approval test (set to 30 days)
+- `Fixture`
+  - `texttest_fixture.php` used by the approval test, or can be run from the command line
+
+## Testing
+
+PHPUnit is pre-configured to run tests. PHPUnit can be run using a composer script. To run the unit tests, from the
+ root of the PHP project run:
+
+```shell script
+composer test
+```
+
+On Windows a batch file has been created, similar to an alias on Linux/Mac (e.g. `alias pu="composer test"`), the same
+ PHPUnit `composer test` can be run:
+
+```shell script
+pu
+```
+
+### Tests with Coverage Report
+
+To run all test and generate a html coverage report run:
+
+```shell script
+composer test-coverage
+```
+
+The test-coverage report will be created in /builds, it is best viewed by opening **index.html** in your browser.
+
+## Code Standard
+
+Easy Coding Standard (ECS) is used to check for style and code standards, **PSR-12** is used. The current code is not
+ upto standard!
+
+### Check Code
+
+To check code, but not fix errors:
+
+```shell script
+composer check-cs
+``` 
+
+On Windows a batch file has been created, similar to an alias on Linux/Mac (e.g. `alias cc="composer check-cs"`), the
+ same PHPUnit `composer check-cs` can be run:
+
+```shell script
+cc
+```
+
+### Fix Code
+
+There are may code fixes automatically provided by ECS, if advised to run --fix, the following script can be run:
+
+```shell script
+composer fix-cs
+```
+
+On Windows a batch file has been created, similar to an alias on Linux/Mac (e.g. `alias fc="composer fix-cs"`), the same
+ PHPUnit `composer fix-cs` can be run:
+
+```shell script
+fc
+```
+
+## Static Analysis
+
+PHPStan is used to run static analysis checks:
+
+```shell script
+composer phpstan
+```
+
+On Windows a batch file has been created, similar to an alias on Linux/Mac (e.g. `alias ps="composer phpstan"`), the
+ same PHPUnit `composer phpstan` can be run:
+
+```shell script
+ps
+```
+
+**Happy coding**!
