 # Balancer Asset Repository
 
+## How to add a token to Balancer
+
+To add a token, the bytecode must be verified.  For example [https://etherscan.io/verifyContract](Verify Contract on Etherscan)
+Furthermore, it must not be a rebasing token, as these are incompatible with the balancer v2 vault
+
+The tokens should be added to the appropriate list(s) below and then pull requested so they can be subject to community review.  In most cases, for a token to be on the balancer ui, it should be added to `/lists/listed.json` and `/lists/ui-not-eligible.json`.
+
+If a custom token icon is to be used, a png named `<token address>.png` should be added to the `/assets/` folder, and the token address should be added to `/assets/index.json`
+
+If the token is incompatible with balancer - such as a rebasing token - please add it to `/lists/untrusted.json`
+
