+# Core Dev Team Work Tracking & Managment
+
+## How work gets organized (a tl;dr;)
+
+The js-ipfs core working group follows the OKR structure established for the IPFS project to set the quarterly targets. Within each quarter, work gets tracked using Github and Waffle.
+
+- Github is used for discussions and track current endeavours.
+- Waffle gives us a [Kanban](https://en.wikipedia.org/wiki/Kanban) view over the work at hand.
+
+![](https://ipfs.io/ipfs/QmWNd86qtjyFnygSAHkZDy4fUB1WnRa4WNt8gt1rSiq7of)
+
+In the Waffle board, we have 4 columns:
+
+- **Inbox** - New issues or PRs that haven't been evaluated yet
+- **Backlog** - Issues that are blocked or discussion threads that are not currently active
+- **Ready** - Issues Ready to be worked on
+- **In Progress** - Issues that someone is already tackling. Contributors should focus on a few things rather than many at once.
+- **Done** - Issues are automatically moved here when the issue is closed or the PR merged.
+
+We track work for the JavaScript implementation of the IPFS protocol in 3 separate waffle boards:
+
+- [js-ipfs](http://waffle.io/ipfs/js-ipfs)
+- [js-libp2p](http://waffle.io/libp2p/js-libp2p)
+- [js-ipld](http://waffle.io/ipld/js-ipld)
+
+## Issue labels and how to use filters
+
+We use labels to tag urgency and the difficulty of an issue. The current label system has:
+
+- `difficulty:{easy, moderate, hard}` - This is an instinctive measure give by the project lead or leads. It is a subjective best guess, however the current golden rule is that an issue with difficulty:easy should not require more than a morning (3~4 hours) to do and it should not require having to mess with multiple modules to complete. Issues with difficulty moderate or hard might require some discussion around the problem or even request that another team (i.e go-ipfs) makes some changes. The length of moderate or hard issue might be a day to ad-aeternum.
+- `priority (P0, P1, P2, P3, P4)` - P0 is the most important while P4 is the least.
+- `help wanted` - Issues perfect for new contributors. They will have the information necessary or the pointers for a new contributor to figure out what is required. These issues are never blocked on some other issue be done first.

 ## Background
 
-libp2p is the product of a long and arduous quest to understand the evolution of the Internet networking stack. In order to build P2P applications, dev have long had to made custom ad-hoc solutions to fit their needs, sometimes making some hard assumptions about their runtimes and the state of the network at the time of their development. Today, looking back more than 20 years, we see a clear pattern in the types of mechanisms built around the Internet Protocol, IP, which can be found throughout many layers of the OSI layer system, libp2p distils these mechanisms into flat categories and defines clear interfaces that once exposed, enable other protocols and applications to use and swap them, enabling upgradability and adaptability for the runtime, without breaking the API.

+
+Stats are not updated in real-time. Instead, measurements are buffered and stats are updated at an interval. The maximum interval can be defined through the `Switch` constructor option `stats.computeThrottleTimeout`, defined in miliseconds.

+1. Install the modules, `npm install`.

+## Running
+1. Run the listener in window 1, `node listener.js`
+2. Run the dialer in window 2, `node dialer.js`
+3. You should see console logs showing the dial, and the received echo of _hey_

 # Publish Subscribe
 
-Publish Subscribe is something out of scope for the modular networking stack that is libp2p, however, it is something that is enabled through the primitives that libp2p offers and so it has become one of the most interesting use cases for libp2p.

-Currently, we have a PubSub implementation, [libp2p-floodsub](https://github.com/libp2p/js-libp2p-floodsub) and many more being researched at [research-pubsub](https://github.com/libp2p/research-pubsub).
