+# Permissionless Software Foundation Community Contributing Guide 1.0
+
+This document describes a very simple process suitable for most projects under
+the PSF umbrella. It is based on [this Medium article](https://medium.com/the-node-js-collection/healthy-open-source-967fa8be7951) and the [Node.js Community Contribution Guide](https://github.com/nodejs/TSC/blob/master/BasePolicies/CONTRIBUTING.md).
+Projects are encouraged to adopt this whether they
+are hosted under the PSF or not.
+
+The goal of this document is to create a contribution process that:
+
+* Encourages new contributions.
+* Encourages contributors to remain involved.
+* Avoids unnecessary processes and bureaucracy whenever possible.
+* Creates a transparent decision making process which makes it clear how
+contributors can be involved in decision making.
+
+This document is based on much prior art in the Node.js community, io.js,
+and the Node.js project.
+
+Additional guidance can be found at the [Permissionless Software Foundation Telegram Channel](https://t.me/permissionless_software).
+
+## Vocabulary
+
+* A **Contributor** is any individual creating or commenting on an issue or pull request.
+* A **Committer** is a subset of contributors who have been given write access to the repository.
+* A **TC (Technical Committee)** is a group of committers representing the required technical
+expertise to resolve rare disputes.
+
+# Logging Issues
+
+Log an issue for any question or problem you might have. When in doubt, log an issue,
+any additional policies about what to include will be provided in the responses. The only
+exception is security disclosures which should be sent privately.
+
+Committers may direct you to another repository, ask for additional clarifications, and
+add appropriate metadata before the issue is addressed.
+
+Please be courteous, respectful, and every participant is expected to follow the
+project's Code of Conduct.
+
+# Contributions
+
+Any change to resources in this repository must be through pull requests. This applies to all changes
+to documentation, code, binary files, etc. Even long term committers and TC members must use
+pull requests.
+
+No pull request can be merged without being reviewed.
+
+For non-trivial contributions, pull requests should sit for at least 36 hours to ensure that
+contributors in other timezones have time to review. Consideration should also be given to
+weekends and other holiday periods to ensure active committers all have reasonable time to
+become involved in the discussion and review process if they wish.
+
+The default for each contribution is that it is accepted once no committer has an objection.
+During review committers may also request that a specific contributor who is most versed in a
+particular area gives a "LGTM" before the PR can be merged. There is no additional "sign off"
+process for contributions to land. Once all issues brought by committers are addressed it can
+be landed by any committer.
+
+In the case of an objection being raised in a pull request by another committer, all involved
+committers should seek to arrive at a consensus by way of addressing concerns being expressed
+by discussion, compromise on the proposed change, or withdrawal of the proposed change.
+
+If a contribution is controversial and committers cannot agree about how to get it to land
+or if it should land then it should be escalated to the TC. TC members should regularly
+discuss pending contributions in order to find a resolution. It is expected that only a
+small minority of issues be brought to the TC for resolution and that discussion and
+compromise among committers be the default resolution mechanism.
+
+# Becoming a Committer
+
+All contributors who land a non-trivial contribution should be on-boarded in a timely manner,
+and added as a committer, and be given write access to the repository.
+
+Committers are expected to follow this policy and continue to send pull requests, go through
+proper review, and have other committers merge their pull requests.
+
+# TC Process
+
+The TC uses a "consensus seeking" process for issues that are escalated to the TC.
+The group tries to find a resolution that has no open objections among TC members.
+If a consensus cannot be reached that has no objections then a majority wins vote
+is called. It is also expected that the majority of decisions made by the TC are via
+a consensus seeking process and that voting is only used as a last-resort.
+
+Resolution may involve returning the issue to committers with suggestions on how to
+move forward towards a consensus. It is not expected that a meeting of the TC
+will resolve all issues on its agenda during that meeting and may prefer to continue
+the discussion happening among the committers.
+
+Members can be added to the TC at any time. Any committer can nominate another committer
+to the TC and the TC uses its standard consensus seeking process to evaluate whether or
+not to add this new member. Members who do not participate consistently at the level of
+a majority of the other members are expected to resign.

 ## 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.

 1. Follow the direction in [this Gist](https://gist.github.com/christroutner/a39f656850dc022b60f25c9663dd1cdd) to install Node.js, Docker, and Docker Compose.

   - `node create-wallet.js`

+1. Change directory to the `production/docker` folder.
 1. Pull the Docker images down from Docker Hub: `docker-compose pull`
+1. Build the core software: `docker-compose build --no-cache`
 1. Start the Docker containers 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).
 
 ## Blockchain Infrastructure
 
-The P2WDB and bch-dex containers requires a 'Global Back End' (as described in [CashStack.info](https://cashstack.info)) in order to connect to the blockchain. By default, the Docker containers connect to [free-bch.fullstack.cash](https://free-bch.fullstack.cash/). Several community-provided Global Back End servers are provided and can be [viewed here](https://gist.github.com/christroutner/63c5513782181f8b8ea3eb89f7cadeb6). The back end can be changed by setting the `CONSUMER_URL` environment variable in the `docker-compose.yml` file.
-
-### Applying Software Updates
-As this is an active project, software updates will happen frequently. To apply a software update, perform these steps.
-
-
-1. Enter the `docker` or `rpi-docker` folder, depending on your hardware target.
-1. Bring down the Docker containers with `docker-compose down`.
-1. Pull in the software updates with `git pull`
-1. Update dependencies with `npm install`
-1. Pull new Docker images with `docker-compose pull`
-1. Clean up disk space by deleting old Docker images with `./cleanup-images.sh`
-1. Start the Docker containers with `docker-compose up -d`
-
-
-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.
+bch-dex requires a [Cash Stack](https://cashstack.info) back end in order to connect to the blockchain. By default, the Docker containers connect to [free-bch.fullstack.cash](https://free-bch.fullstack.cash/). Several community-provided servers are provided and can be [viewed here](https://consumers.psfoundation.info/consumers.json). The back end can be changed by setting the `CONSUMER_URL` environment variable in the `docker-compose.yml` file.
