+# 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.

 ### Development Environment
 
+**Note:** This software now uses an external go-ipfs IPFS node. The instructions below have not been updated to reflect this.
+
 A development environment will allow you modify the code on-the-fly and contribute to the code base of this repository. [PM2](https://www.npmjs.com/package/pm2) is recommended for running this code base as an IPFS Circuit Relay.

+- You can bring the containers back up with `docker-compose up -d`.
 
-- There is a memory leak in the version of js-ipfs. The app is currently configured to shut down every 8 hours to flush memory. It relies on a process manager like pm2, Docker, or systemd to restart the app after it shuts down, in order to ensure continuous operation.

+# Developer Documentation
+
+This directory needs to be fleshed out with more information. The markdown files in this directory are intended to provide additional documentation for software developers that use this boilerplate to run their own forks.
+
+## Startup
+This software requires an IPFS node in order to operate the JSON RPC and ipfs-coord features. There are two ways to incorporate an IPFS node:
+
+- js-ipfs is integrated into this repository. If you simply run `npm start`, then this app will default to the js-ipfs IPFS node. However, js-ipfs is not as full featured as go-ipfs. It has memory leaks and lags considerably behind go-ipfs in terms of features.
+
+- go-ipfs is the preferred way to run a node. It can be run externally by following the guidence on the [IPFS homepage](https://ipfs.io). Once the IPFS node is running, this app can take control of it. Use the [local-external-ipfs-node.sh](../shell-scripts/local-external-ipfs-node.sh) shell script to start this app and attach it to the go-ipfs node.

+# 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.
