+This repository contains the **default token list** used by the Uniswap interface.

-[file an issue](https://github.com/Uniswap/default-token-list/issues/new?assignees=&labels=token+request&template=token-request.md&title=Add+%7BTOKEN_SYMBOL%7D%3A+%7BTOKEN_NAME%7D).
+## What is a Token List?
 
-### Disclaimer
+A token list is a JSON file that contains information about tokens such as:
+- Token addresses
+- Names
+- Symbols
+- Logos
+- Decimals
 
-Note filing an issue does not guarantee addition to this default token list.
-We do not review token addition requests in any particular order, and we do not
-guarantee that we will review your request to add the token to the default list.
+This list is used by the Uniswap app to show tokens to users and help them interact safely.
