 # featurevisor-example-php
 
-Example PHP application using Featurevisor PHP SDK: https://github.com/featurevisor/featurevisor-php
+A small PHP application showing how to use the [Featurevisor PHP SDK](https://github.com/featurevisor/featurevisor-php).
 
-Learn more about Featurevisor: https://featurevisor.com
+Learn more about Featurevisor [here](https://featurevisor.com).
 
-## Installation
+It fetches a production datafile, creates a Featurevisor instance with customer context, then evaluates a flag, a variation, feature variables, and global variables.
 
-Clone the repository, and run this with Composer:
+## Installation
 
+```sh
+composer install
 ```
-$ composer install
+
+## Run the example
+
+```sh
+php src/index.php
 ```
 
-## Usage
+The application evaluates `commerce_platform`, `checkout_experience`, `max_items`, `payment_methods`, `serviceEndpoints`, and `supportContact` from this datafile:
 
+```text
+https://featurevisor-example-cloudflare.pages.dev/production/featurevisor-sdk-v3.json
 ```
-$ php src/index.php
+
+Expected output:
+
+```text
+Commerce platform enabled: true
+Checkout variation: express
+Maximum checkout items: 25
+Payment methods: [card, wallet]
+Service endpoint: https://api.eu.example.com (timeout: 1200 ms, retries: 4)
+Support contact: support-nl@example.com
 ```
 
+Change the context in `src/index.php` to see how Featurevisor selects different rules, variations, and global variable overrides.
+
 ## Featurevisor project
 
-Uses this Featurevisor project to fetch the configuration from: https://github.com/featurevisor/featurevisor-example-cloudflare
+The datafile is generated by the [Featurevisor Cloudflare example](https://github.com/featurevisor/featurevisor-example-cloudflare).
+
+Learn more in the [Featurevisor PHP SDK documentation](https://featurevisor.com/docs/sdks/php/).
