+# PancakeSwap Token Lists
+
+This repo contains main PancakeSwap token list and tools to validate it.
+
+## How to add external lists
+
+URLs to external lists are stored in `token-lists.json`, if you want your list to be available on upcoming list UI page - submit a PR modifying `token-lists.json`.
+
+## How to add new lists within this repository
+
+- Add an array of tokens under `src/tokens`
+- Add `checksum:newlistname`, `generate:newlistname`, `makelist:newlistname` command to `package.json` analogous to PancakeSwap default and extended list scripts.
+- Modify `checksum.ts`, `buildList.ts` and `default.test.ts` to handle new list
+
+## How to add new tokens to pancakeswap (extended) token list
+
+Note - this is not something we expect pull requests for.  
+Unless you've been specifically asked by someone from PCS team please do no submit PRs to be listed on default PCS list. You can still trade your tokens on PCS exchange by pasting your address into the token field.
+
+- Update version in `package.json`
+- Add new tokens to `src/tokens/pancakeswap-extended.json` file
+- Run `yarn makelist:pcs-extended`
+- If tests pass - new token list will be created under `lists` directory
+
+For list to be considered valid it need to satisfy the following criteria:
+
+- It passes [token list schema](https://github.com/Uniswap/token-lists/blob/master/src/tokenlist.schema.json) validation (schema is [slightly modified](src/schema.ts))
+- There are no duplicate addresses, symbols or token names in the list
+- All addresses are valid and checksummed (`yarn checksum:pcs` automatically converts addresses to checksummed versions, it is also part of `yarn makelist:pcs`)
+
+## Deploying
+
+Token lists will be auto-deployed via netlify when PR is merged to master. Be sure to build the list with `yarn makelist:list-name` before submitting/merging the PR since it doesn't make much sense building lists within Netlify (because most errors are related to wrong token information and should be fixed prior to landing into master)
+
+Netlify simply takes the json files under `lists` directory and hosts them on `tokens.pancakeswap.finance/list-name.json`
