How to Modify original setup

Download and extract matomo from https://matomo.org/download/
Copy this custom-api.php into the matomo root folder.
Install Guzzle via composer in the matomo folder using the following command
```
composer require guzzlehttp/guzzle:~6.0
```
More about Guzzle installtion at http://docs.guzzlephp.org/en/stable/overview.html#installation
Guzzle has the dependency facebook/xhprof which will be added as git sub module, So in need to be changed before committing it to VBXAnalytix repo
```
git rm --cached vendor/facebook/xhprof
```
The above command keeps the files and removes the sub module structure
