-## Developing Compatible Dapps
-
-If you're a web dapp developer, we've got two types of guides for you:
-
-### New Dapp Developers
-
-- We recommend this [Learning Solidity](https://karl.tech/learning-solidity-part-1-deploy-a-contract/) tutorial series by Karl Floersch.
-- We wrote a (slightly outdated now) gentle introduction on [Developing Dapps with Truffle and MetaMask](https://medium.com/metamask/developing-ethereum-dapps-with-truffle-and-metamask-aa8ad7e363ba).
-
-### Current Dapp Developers
-
-- If you have a Dapp, and you want to ensure compatibility, [here is our guide on building MetaMask-compatible Dapps](https://github.com/MetaMask/faq/blob/master/DEVELOPERS.md)
+To learn how to contribute to the MetaMask project itself, visit our [Internal Docs](https://github.com/MetaMask/metamask-extension/tree/develop/docs).
