+Support & Sponsorship
+---------------------
+The PHP Solr Extension has been around since 2010 without any financial backing. Today, We'd like to transform it into an ODM (Object Document Mapper), a milestone we can't reach without your support, as there will be significant work up ahead. [Giving back will help us in this transformation](https://opencollective.com/php-solr-extension)!
