 # Contrib
 
-Resources and examples for running and interacting with the kava blockchain.
+Resources and examples for running and interacting with the kava blockchain. `contrib` contains sample genesis files, example governance proposals, and rest-server request examples for different versions of kava.
+
+## testnet-4000
+
+kava-testnet-4000 introduces the cdp and auction modules, allowing users to create CDPs and mint usdx as well as participate in auctions.
+
+Configuration and rest-server interaction files are available in the [testnet-4000](./testnet-4000/README.md) directory.
+
+## testnet-5000
+
+kava-testnet-5000 introduces the bep3 modules, allowing users to transfer BNB between the bnbchain testnet and kava.
+
+Configuration and rest-server interaction files are available in the [testnet-5000](./testnet-5000/README.md) directory.
+
+## dev
+
+During development new features offer require modifications to the genesis file. The dev directory houses these genesis files.

 ### Create CDP example request
 
- Format the base request in create-cdp.json. You'll need to update the 'from', 'chain-id', 'account_number', 'sequence', and 'gas' as appropriate. Then, populate the CDP creation request's params 'owner', 'collateral', and 'principal'. An example formatted request can be found in `example-create-cdp.json`.

 ### Post market price example request
 
- Note that only market oracles can post prices, other senders will have their transactions rejected by Kava.
+Note that only market oracles can post prices, other senders will have their transactions rejected by Kava.
 
- Format the base request in post-price.json. You'll need to update the 'from', 'chain-id', 'account_number', 'sequence', and 'gas' as appropriate. Then, populate the post price request's params 'from', 'market_id', 'price', and 'expiry'. An example formatted request can be found in `example-post-price.json`.
