 ## Callbacks
 
-There are 2 types of callbacks users can use when transfering an NFT:
+cw-ics721 supports [callbacks](./packages/ics721-types/src/types.rs#L67-L70) for Ics721ReceiveCallback and Ics721AckCallback.
 
 1. Receive callback - Callback that is being called on the receiving chain when the NFT was succesfully transferred.
 2. Ack callback - Callback that is being called on the sending chain notifying about the status of the transfer.
 
+Workflow:
+
+1. `send_nft` from cw721 -> cw-ics721.
+2. `send_nft` holds `IbcOutgoingMsg` msg.
+3. `IbcOutgoingMsg` holds `Ics721Memo` with optional receive (request) and ack (response) callbacks.
+4. `cw-ics721` on target chain executes optional receive callback.
+5. `cw-ics721` sends ack success or ack error to `cw-ics721` on source chain.
+6. `cw-ics721` on source chain executes optional ack callback.
+
+NOTES:
+
+In case of 4. if any error occurs on target chain, NFT gets rolled back and return to sender on source chain.
+In case of 6. ack callback also holds `Ics721Status::Success` or `Ics721Status::Failed(String)`

 In order to execute an ack callback, `ack_callback_data` must not be empty. In order to execute a receive callback, `receive_callback_data` must not be empty.

+# Setup ICS721
+
+For ICS721 it requires these contracts:
+
+- ICS721: the bridge itself
+- Incoming Proxy: optional contract for filtering incoming packets
+- Outgoing Proxy: optional contract for filtering incoming packets
+
+NOTE:
+Below scripts use [select-chain.sh](./select-chain.sh). For each selected chain there is an `.env` file like `stargaze.env` and `osmosis.env`.
+
+## Scripts
+
+### Initial Setup
+
+Scripts for setup must be executed in this order:
+
+1. ICS721 without proxies: [instantiate-ics721.sh](./instantiate-ics721.sh)
+2. Incoming Proxy: [instantiate-incoming-proxy.sh](./instantiate-incoming-proxy.sh)
+3. Outgoing Proxy: [instantiate-outgoing-proxy.sh](.instantiate-outgoing-proxy.sh)
+
+After instantiation:
+
+- update `ADDR_ICS721`, `ADDR_INCOMING_PROXY`, `ADDR_OUTGOING_PROXY` in env file
+- Note: ICS721 is instantiated without(!) proxies, proxies are added via migration (velow)
+
+### Migration
+
+1. ICS721 : [migrate-ics721.sh](./migrate-ics721.sh)
+2. Incoming Proxy: [migrate-incoming-proxy.sh](./migrate-incoming-proxy.sh)
+3. Outgoing Proxy: [migrate-outgoing-proxy.sh](.migrate-outgoing-proxy.sh)
+
+### Outgoing Proxy Messages
+
+Usage:
+
+```sh
+$ ./scripts/whitelist-outgoing-proxy.sh
+Usage: ./scripts/whitelist-outgoing-proxy.sh stargaze|osmosis [--add WHITELIST|--remove WHITELIST|--enable true_or_false] --type collection|channel|checksum|fees
+Example:
+./scripts/whitelist-outgoing-proxy.sh stargaze|osmosis --add channel-1 --type channel
+./scripts/whitelist-outgoing-proxy.sh stargaze|osmosis --enable false --type collection
+```
+
+The owner of the outgoing proxy contract can add, remove and enable whitelists for collections, channels, collection checksums, and collection fees.
