-This is a prototype web service that monitors the [P2WDB](https://github.com/Permissionless-Software-Foundation/ipfs-p2wdb-service) for trading signals, to trade BCH and SLP tokens. It's inspired by the [SWaP Prototype](https://github.com/vinarmani/swap-protocol/blob/master/swap-protocol-spec.md).
+`bch-dex` is a decentralized exchange for permissionless trading of [SLP tokens](https://github.com/simpleledger/slp-specifications/blob/master/slp-token-type-1.md) and [NFTs](https://github.com/simpleledger/slp-specifications/blob/master/slp-nft-1.md). Trading fees are incredibly small, compared to other DEX platforms. The software is based entirely on open protocols and open source software. It's not a '.com' website that you visit, but software you run on your own computer, in the confort of your own home. So long as you have an internet connection and the technical knowledge to run this software, no one can stop you from trading tokens. `bch-dex` software is maintained by the [Permissionless Software Foundation](https://psfoundation.cash/).

+
+This repository contains the back end code. The user interface is contained in the [bch-dex-ui](https://github.com/Permissionless-Software-Foundation/bch-dex-ui) repository.
 
 **Warning**: This repository is under active development. Things will be constantly changing and breaking.

-- Phase 1: MVP (single user)
-  - Move tokens or BCH for sale to temporary address.
-  - Accept input from user:
-    - Submit Signal message to P2WDB for new buy/sell order.
-    - Check UTXO status before submitting Payment message.
-  - React to webhook when new Offers come in.
-    - Add and track new Offers in MongoDB.
-    - Process Payment signals:
-      - Checking transaction for compatibility
-      - Broadcast/close trades managed by this app.
-- Phase 2: Build single-user web app
-  - _Make_ buy or sell orders.
-  - Browse Offers on the market.
-  - _Take_ buy or sell orders.
-- Phase 3: Multi-user
-  - Configure REST API as an IPFS Service that can offer services to multiple users.
-  - Update web app to display and select available SWaP services over IPFS.
+## Participate
+This is an open source project, and we encourage other JavaScript developers to participate in its creation and maintenance. We have two chat rooms for the community:
+- [Telegram Channel](https://t.me/psf_dex_dev)
+- [Gitter Channel](https://gitter.im/Permissionless-Software-Foundation/psf-dex-dev)
+
+## Installation
+Running the DEX requires composition of these different software packages:
+- bch-dex - This repository is the back end software that tracks trade data on the network, generates [Offers and Counter Offers](https://github.com/Permissionless-Software-Foundation/bch-dex/tree/ct-unstable/dev-docs#definitions), and finalizes trades by accepting Counter Offers.
+- [bch-dex-ui](https://github.com/Permissionless-Software-Foundation/bch-dex-ui) is a [Gatsby](https://www.gatsbyjs.com/) web app and user interface (UI) for bch-dex.
+- [P2WDB](https://github.com/Permissionless-Software-Foundation/ipfs-p2wdb-service) is a censorship-resistant database used to communicate trade data between peers running bch-dex.
+- [IPFS](https://ipfs.io/) is a censorship-resistant network for communicating data over the internet.
+- [MongoDB](https://www.mongodb.com/) is a database used by both P2WDB and bch-dex to store and manage local data.
+
+The above software is orchestrated using [Docker](https://www.docker.com/) and Docker Compose. The target operating system is Ubuntu 20+, and the target hardware is amd64 (normal desktop PCs) and the arm64 (Raspberry Pi 4). Trying to operate this software on other operating systems or hardware is possible, but not supported.
+
+Instructions for setting up Node.js, Docker, and Docker Compose can be found in [this Gist](https://gist.github.com/christroutner/a39f656850dc022b60f25c9663dd1cdd). Walk-through videos can also be found on the [PSF Videos page](https://psfoundation.cash/video/).
+
+Building the Docker containers and getting the app working involve these steps:
+
+1. Follow the direction in [this Gist](https://gist.github.com/christroutner/a39f656850dc022b60f25c9663dd1cdd) to install Node.js, Docker, and Docker Compose.
+1. Clone the repository with `git clone https://github.com/Permissionless-Software-Foundation/bch-dex` and enter it with `cd bch-dex`.
+1. Install dependencies by running `npm install`
+1. Create a wallet by executing the [create-wallet.js script](./production/scripts/create-wallet.js) with `node create-wallet.js`
+1. Move the `wallet.json` file to the `bch-dex` folder in either the [x86 Docker folder](./production/docker/bch-dex) or the [RPi Docker folder](./production/rpi-docker/bch-dex/) depending on your hardware target.
+1. Change directory to the `docker` or `rpi-docker` folder depending on your hardware target.
+1. Build the Docker containers with `docker-compose build --no-cache`.
+1. Start the Docker containers with `docker-compose up -d`
+1. Wait for the containers to run for about a minute, then bring them down with `docker-compose down`. That will create the needed folders in `production/data`.
+1. Copy the `swarm.key` into the `production/data/go-ipfs/data/` directory. This will allow the IPFS node to connect to the PSF private network.
+1. Bring the containers back up with `docker-compose up -d`.
+1. Wait for the P2WDB to sync and populate bch-dex with trade data. You can monitor it with `docker logs --tail 20 -f p2wdb`.
+1. Open a web browser and navigate the `http://localhost:4500`. You'll be able to see new Offers as they come in and are detected by bch-dex.
+1. To take the other side of the trade, click the `Take` button in the UI.
+1. You can add the 12-word mnemonic from the `wallet.json` file to the the web wallet, which will mirror your wallet in the UI, and allow you to perform basic wallet functions (send and receive BCH and tokens).
+
+
+### Applying Software Updates
+As this is an active project, software updates will happen frequently. To apply a software update, perform these steps.
+
+<ol>
+  <li>Enter the `docker` or `rpi-docker` folder, depending on your hardware target.</li>
+<li>Bring down the Docker containers with `docker-compose down`.</li>
+<li>Pull in the software updates with `git pull`</li>
+<li>Update dependencies with `npm install`</li>
+<li>Rebuild the Docker containers with `docker-compose build --no-cache`</li>
+<li>Clean up disk space by deleting old Docker images with `./cleanup-images.sh`</li>
+<li>Start the Docker containers with `docker-compose up -d`</li>
+</ol>
+
+Sometimes it may be necessary to delete the databases before applying a software update. This can be done by stopping the Docker containers and deleting the `production/data` directory. When the Docker containers are restarted, they will recreate that directory. The P2WDB will re-sync and bch-dex will be populated with fresh trade data.

-# 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.
