 ## The future of the Firebase Admin PHP SDK
 
-Development of this SDK has cost thousands of hours of work and the vast majority
-of work has been done by one, mostly unpaid, contributor, [@jeromegamez](https://github.com/jeromegamez).

-The number of monthly downloads shows that many corporate/agency users rely heavily
-on the SDK; however, very few have contributed, and none have given back and

 **Unless funding is found to continue maintaining the SDK, maintenance will be halted.**
 
-The funding goal is a **recurring $5,000/month**. Reaching and maintaining this goal will allow me
-to continue maintaining and developing the SDK. You can see the current progress on reaching this
-goal on [@jeromegamez's Sponsor Page](https://github.com/sponsors/jeromegamez). Funding outside of
-GitHub will reduce the goal.

-This is a call to action for the business users of the SDK to figure out a way to
-fund the continued maintenance and development of the SDK, as the one person
-on which the whole project leans is done with the current status quo.
+The goal will be reduced when funding is provided outside of GitHub. A fork of the SDK with continued support
+will be made available to all $500+ sponsors.
