 JavaScript SDK for [CoTA](https://talk.nervos.org/t/rfc-cota-a-compact-token-aggregator-standard-for-extremely-low-cost-nfts-and-fts/6338).
 
+[CoTA Docs](https://developer.mibao.net/docs/develop/cota/overview)
+
 ## Feature
 
 - Provide methods for [cota-aggregator](https://github.com/nervina-labs/cota-aggregator) and [cota-registry-aggregator](https://github.com/nervina-labs/cota-registry-aggregator) RPC APIs
 - Provide methods to generate CoTA operating transactions
 
+## Prerequisites
+
+- [CKB Node](https://docs.nervos.org/docs/basics/guides/testnet)
+- [CKB Indexer](https://github.com/nervosnetwork/ckb-indexer)
+- [CoTA Registry Aggregator](https://github.com/nervina-labs/cota-registry-aggregator)
+- [CoTA Aggregator](https://github.com/nervina-labs/cota-aggregator)
+
+### Public ckb node url and ckb indexer url as blow can be used to develop and test
+
+```
+mainnet
+https://mainnet.ckbapp.dev  --->  ckb mainnet rpc
+https://mainnet.ckbapp.dev/rpc  --->  ckb mainnet rpc
+https://mainnet.ckbapp.dev/indexer  --->  ckb mainnet indexer_rpc
+
+testnet:

+https://testnet.ckbapp.dev/rpc  --->  ckb testnet rpc
+https://testnet.ckbapp.dev/indexer  --->  ckb testnet indexer_rpc
+```
+
 ## Examples
 
 - [aggregator example](https://github.com/nervina-labs/cota-sdk-js/blob/develop/example/aggregator.ts): Fetch CoTA NFT data and [SMT](https://github.com/nervosnetwork/sparse-merkle-tree) data from Aggregator server

+- [define example](https://github.com/nervina-labs/cota-sdk-js/blob/develop/example/define.ts): Generate defining CoTA cells transaction
 - [mint example](https://github.com/nervina-labs/cota-sdk-js/blob/develop/example/mint.ts): Generate minting CoTA NFT transaction
 - [claim example](https://github.com/nervina-labs/cota-sdk-js/blob/develop/example/claim.ts): Generate claiming CoTA NFT transaction
 - [withdraw example](https://github.com/nervina-labs/cota-sdk-js/blob/develop/example/withdraw.ts): Generate withdrawing CoTA NFT transaction
 - [transfer example](https://github.com/nervina-labs/cota-sdk-js/blob/develop/example/transfer.ts): Generate transferring CoTA NFT transaction
