+A Counter Offer is the other side of the trade, a mirror image to an Offer. It contains a partially signed transaction, created by the Taker. The Maker will review the Counter Offer before accepting and finalizing the trade.
+
+Counter Offers are not tracked via database models like Offers and Orders are. They are processed by `bch-dex` as soon as they are received. A garbage collection function will be called periodically, to sweep the segregated UTXOs used to generate a Counter Offer back into the root address of the wallet, if it is not accepted after a period of time.
+
+To generate a Counter Offer, a segregated UTXO is created that matches the requirements in the Offer. A partially signed transaction is created that includes the Offer UTXO and the Counter Offer UTXO. The Taker signs the input consuming the Counter Offer UTXO. The partially signed transaction and other trade data is uploaded to P2WDB.

+- *dataType* - Must have a value of `counter-offer`
 
-Details TBD.
 
 ## Use Cases
 
 Use cases are verbs or actions that is done _to_ an Entity or _between_ Entities.
 
-### Offer
-
-- **`createOffer()`** - This method is triggered by a webhook from the P2WDB. It will take the data provided by the P2WDB and create a new Order entity in the local database.
-
 ### Order
 
+- **`createOrder()`** - A macro command that leverages the other functions in this library to create a new Order and submit it to the P2WDB.
 - **`ensureFunds()`** - Ensure that the wallet has enough BCH and tokens to complete the requested trade.
-- **`moveTokens()`** - Move the tokens indicated in the order to a temporary holding address. This will generate the UTXO used in the webhook message. This function moves the funds and returns the UTXO information.
-- **`createOrder()`** - A macro command that leverages `ensureFunds()` and `moveTokens()`, to create a new Order and submit it to the P2WDB.
+- **`findOrderByHash()`** - Given a P2WDB CID 'hash', this function will return the corresponding Order model associated with that CID.
 
-### Counter Offer
+### Offer
 
-TBD
+- **`createOffer()`** - This method is triggered by a webhook from the P2WDB. It will take the data provided by the P2WDB and create a new Offer entity in the local database.
+- **`listOffers()`** - Returns a list of all the active Offers tracked by `bch-dex`.
+- **`takeOffer()`** - Generate a segregated UTXO and partially signed transaction, then upload the Counter Offer data to the P2WDB.
+- **`ensureFunds()`** - Ensure the wallet has enough BCH and tokens to make a Counter Offer.
+- **`findOfferByHash()`** - Given a P2WDB CID 'hash', this function will return the corresponding Offer model associated with that CID.
+- **`acceptCounterOffer()`** - This function is triggered by the P2WDB webhook REST API handler. When a Counter Offer is passed to `bch-dex` by the P2WDB, the data is then passed to this function. It does due diligence on the Counter Offer, then signs and broadcasts the transaction to accept the Counter Offer.
 
 ## Controllers
 
 Controllers are inputs to the system. When a controller is activated, it causes the system to react in some way.
 
-### Offers
-
-- **POST /offer** - This POST REST API endpoint will be triggered by a webhook generated from P2WDB. This will notify the `bch-dex` that a new entry has been added to the P2WDB that matches the `appId` of `swap-<chain>`, where `<chain>` has a value of `avax`, `bch`, or `ecash`. It's a new entry that should be evaluated for inclusion in the `ipfs-swap-service` local database.
-
 ### Orders
 
-- **POST /order** - This POST REST API endpoint can be triggered by the Client or a simple curl call. It passes in the data needed for `bch-dex` to generate and track a new Order, then submit the data to the P2WDB to generate an Offer that is tracked by all other instances of `bch-dex`.
+- **POST /order** - This POST REST API endpoint can be triggered by the Client or a simple curl call.

+
+### Offers
+
+- **GET /offer/list** - Returns an array of objects, where each object represents an active Offer.
+
+- **POST /offer/take** - Given the P2WDB CID of an Offer, calling this endpoint will attempt to generate a Counter Offer and upload it to the P2WDB.
+
+### P2WDB
+
+- **POST /p2wdb** - This POST REST API endpoint will be called by a webhook generated from the P2WDB. This will notify the `bch-dex` that a new entry has been added to the P2WDB that matches the `appId` of `swap-<chain>`, where `<chain>` has a value of `avax`, `bch`, or `ecash`. It's a new entry that should be evaluated for inclusion in the `bch-dex` local database. Based on the `dataType` property, the data is routed to either create a new Offer or to process a new Counter Offer.

+Adapters are outputs. These libraries exist so that the business logic doesn't need to know any specific information about the I/O. They handle the low-level mechanics of the various subsystems.
 
 - **localdb** - An adapter for the local database (MongoDB).
 - **ipfs** - An adapter for IPFS and the ipfs-coord library. It allows the app to use the JSON-RPC over IPFS.
+- **wallet** - Handles low-level wallet tasks.
+  - **`moveTokens()`** - Move the tokens indicated in the order to a temporary holding address. This will generate the segregated UTXOs used in the trade. This function moves the funds and returns the UTXO information.
+  - **`moveBCH()`** - Same idea as `moveTokens()`, but creates a non-SLP segregated UTXO, used when generating a Counter Offer.
+  - **`openWallet()`** - Opens the JSON file containing the wallet data for the app.
+  - **`instanceWallet()`** - Given the wallet data returned by `openWallet()`, it generates an instance of the [minimal-slp-wallet](https://www.npmjs.com/package/minimal-slp-wallet) for generating UTXOs and interacting with the blockchain.
+  - **`incrementNextAddress()`** - Increments the index of the [HD wallet](https://github.com/bitcoinbook/bitcoinbook/blob/develop/ch05.asciidoc#hd_wallets) used to generate keypairs for storing segregated UTXOs.
+  - **`getKeyPair()`** - Generates a keypair from the HD wallet.
+  - **`generateSignature()`** - Generate a cryptographic signature.
+  - **`generatePartialTx()`** - Create a partial transaction as part of a Counter Offer.
+  - **`deseralizeTx()`** - Used only for debugging purposes. Expands a hex transaction into a JSON object.
+  - **`completeTx()`** - Complete the partially signed transaction by signing the first input, then broadcasting the transaction to the network.

-# Docker Containers
-
-The 'production' environment is assumed to be a set of Docker containers orchestrated with Docker Compose. The files in this directory will stand up three Docker containers:
-
-1 An instance of go-ipfs.
-2 An instance of MongoDB.
-3 The JavaScript software in this repository.
-
-The software in this repository depends on the first two containers, so if they aren't running correctly, the application won't run correctly either.
-
-## IPFS
-
-IPFS can be a little tricky to set up. By default, the container uses the following ports:
-
-- 4001 for TCP connections, exposed publicly.
-- 5001 for control by the application, exposed privately.
-- 8080 for an IPFS gateway, consumed by the application, exposed privately.
-
-If you already have an IPFS node running on a the computer, you will need to change the ports to avaid a conflict. To change the ports from the default, you'll need to perform a series of steps, and the order of the steps matter.
-
-1. Edit the `docker-compose.yml` file and change the ports. Then save the file. Here is an example:
-
-```
-ports:
-  - 4101:4101
-  - 172.17.0.1:5101:5101
-  - 172.17.0.1:8180:8180
-```
-
-2. Bring the Docker containers up, and then back down. This will allow the IPFS container to create the config file that you'll need to edit.
-
-- `docker-compose up -d`
-- Wait a few seconds.
-- `docker-compose down`
-
-3. Update the generated config file at `../data/go-ipfs/data/config`, to update the ports in the config file, like this:
-
-```
-"Addresses": {
-    "API": "/ip4/0.0.0.0/tcp/5101",
-    "Announce": [],
-    "AppendAnnounce": [],
-    "Gateway": "/ip4/0.0.0.0/tcp/8180",
-    "NoAnnounce": [],
-    "Swarm": [
-      "/ip4/0.0.0.0/tcp/4101",
-      "/ip6/::/tcp/4101",
-      "/ip4/0.0.0.0/udp/4101/quic",
-      "/ip6/::/udp/4101/quic"
-    ]
-  },
-
-```
-
-4. Update the port changes in the `start-production.sh` shell script. This tells the application which ports to use, in order to control the IPFS node, are are used when signaling other nodes.
-
-5. Quickly rebuild the containers, to add the modified `start-production.sh` shell script to the application Docker container:
-
-- `docker-compose build`
-
-6. Now start the containers, and the port changes to IPFS should be complete.
