-## Paid Contributions
-
-At CloudGraph, we believe in paying contributors for their time when it comes to adding new providers. To that end we have initiated a paid provider program as a thank you to the people in the OSS community that want to support us and our mission of creating the GraphQL API for everything. To that end, we pay $1,000 USD for each provider with 10 initial services and authentication. Here are the current providers you can be paid to build out:
-
-- Oracle Cloud
-
-- Ali Cloud
-
-- Digital Ocean
-
-- IMB Cloud
-
-- Open Stack
-
-- Tencent Cloud
-
-- DataDog
-
-- VMware
-
-- HyperV
-
-- Snowflake
-
-Interested in learning more? Here is a [spreadsheet](https://docs.google.com/spreadsheets/d/1twlflwXiMrWJ9VYpVX2whpYvoY715blIKEpejEdy9VY/edit?usp=sharing) shows the desired 10 initial services for each provider. All you have to do to get started is open up an issue with the name of the provider you want to build so everyone knows it's claimed and we will be in touch. Thanks for helping to make OSS a better place!
