+# Guidelines for Submitting CW20 token to Keplr Extension
 
-Index of existing and deployed smart contract for tracking existing code and promotong reusability
+This page outlines the basic information that is required for registering CW20 token to Keplr Extension add token list. Keplr team will go through a minimal verification process to see if there is any security issues or missing information.
 
-Inspired by [Chain Registry](https://github.com/chainapsis/keplr-chain-registry)
+Once approved, Keplr Extension will show CW20 token in token add page, with the information you've submitted.
 
-See the examples for information on the schema in order to contribute.
