+* The easiest way to start is to look at existing [issues](https://github.com/fission/fission/issues) and see if there's something there that you'd like to work on. You can filter issues with label "[Good first issue](https://github.com/fission/fission/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22)" which are relatively self sufficient issues and great for first time contributors.
+    - If you are going to pick up an issue, it would be good to add a comment stating the intention.
+    - If the contribution is a big change/new feature, please raise an issue and discuss the needs, design in the issue in detail.
 
-There's plenty of stuff to do.  If you need help choosing something to
-work on, we'll be happy to suggest something depending on your
-interests.
+* For contributing a new Fission environment, please check the [environments repo](https://github.com/fission/environments)
 
-### Talk to people
+* For contributing a new Keda Connector, please check the [Keda Connectors repo](https://github.com/fission/keda-connectors)
 
-At any point, from thinking about contributing to merging your
-changes, please feel free to reach out to us!  We're more than happy
-to talk.
 
-If you choose a big chunk of work that involves design changes to
-Fission, please talk to us while planning the change; that way we can
-all be on the same page before you invest too much work into it.

+# Contributing - building & deploying
+
+## Prerequisite
+
+- You'll need the `go` compiler and tools installed. Currently version 1.12.x of Go is needed.
+
+- You'll also need [docker](https://docs.docker.com/install) for building images locally.
+
+- You will need a Kubernetes cluster and you can use one of options from below.
+	- [Minikube](https://github.com/kubernetes/minikube)
+	- [Kind](https://kind.sigs.k8s.io/)
+	- Cluster in cloud such as GKE (Google Kubernetes Engine cluster)/ EKS (Elastic Kubernetes Service)/ AKS (Azure Kubernetes Service)
+
+- Kubectl and Helm installed.
+
+- [Skaffold](https://skaffold.dev/docs/install/) for local development workflow to make it easier to build and deploy Fission.
+
+- And of course some basic concepts of Fission such as environment, function are good to be aware of!
+
+## Getting Started
+
+Get the code locally and after you have made changes - you can verify formatting and other basic checks.
+
+```sh
+# Clone the repo
+$ git clone https://github.com/fission/fission.git $GOPATH/src/github.com/fission/fission
+$ cd $GOPATH/src/github.com/fission/fission
+
+$ go mod vendor
+
+# Run checks on your changes
+$ ./hack/verify-gofmt.sh
+$ ./hack/verify-govet.sh
+```
+
+### Use Skaffold with Kind/K8S Cluster to build and deploy
+
+You should bring up Kind/Minikube cluster or if using a cloud provider cluster then Kubecontext should be pointing to appropriate cluster.
+
+* For building & deploying to Cloud Provider K8S cluster such as GKE/EKS/AKS:
+
+```
+$ skaffold config set default-repo vishalbiyani  // (vishalbiyani - should be your registry/Docker Hub handle)
+$ skaffold run
+```
+
+*  For building & deploying to Kind cluster use Kind profile
+```
+$ kind create cluster
+$ kubectl create ns fission
+$ skaffold run -p kind
+```
+
+## Validating Installation
+
+If you are using Helm, you should see release installed:
+
+```
+helm list
+NAME   	NAMESPACE	REVISION	UPDATED                             	STATUS	CHART            	APP VERSION

+```
+
+Also you should see the Fission services deployed and running:
+
+```
+$ kubectl get pods -n fission

+## Understanding code structure
+
+### cmd
+
+`cmd` package is entry point for all runtime components and also has Dockerfile for each component. The actual logic here will be pretty light and most of logic of each component is in `pkg` (Discussed later)

+**fetcher** : is a very lightweight component and all of related logic is in fetcher package itself. Fetcher helps in fetching and uploading code and in specializing environments.
+
+**fission-bundle** : is a component which is a single binary for all components. Based on arguments you pass to fission-bundle - it becomes that component. For ex. 
+
+```

+
+/fission-bundle --kubewatcher --routerUrl http://router.fission  # Runs Kubewatcher

+## Core Components
 
+### Controller
 
-Controller
-----------
+The controller contains CRUD APIs for functions, triggers, environments,
+Kubernetes event watches, etc. This is the component that the client talks to.
 
-The controller contains CRUD APIs for functions, http triggers,
-environments, Kubernetes event watches.  This is the component that
-the client talks to.
+All fission resources are stored in kubernetes CRDs. It needs to be able to
+talk to kubernetes API service.
 
-This is the only stateful component.  It needs to be configured with a
-URL to an etcd cluster and a path to a persistent volume.  The volume
-is used to store the functions' source code.  Etcd is used as the DB.
+### Executor
 
-[Work to extend to other storage backends is planned, see issue #83.]
+The executor has two simple APIs; the router calls both these endpoints.
 
-Pool Manager 
-------------
+* GetFunctionService takes function metadata and dispatches the corresponding executor 
+ type to get the address of a service/pod and returns it to the router.
+ 
+* TapService lets executor know a service/pod is being used; if it's not
+ called for a few minutes the pod(s) backing the service are killed.
 
-Poolmgr manages pools of generic containers and function containers.
+It now supports two different executor types:
 
-It has a simple API; both these endpoints are called by the router.
+* PoolManager
+* NewDeploy
 
-* GetFunctionService takes function metadata and returns the address
-  of a service.
-  
-* TapService lets poolmgr know a service is being used; if it's not
-  called for a few minutes the pod(s) backing the service are killed.
+These two executor types have different strategies to launch, specialize, and manage pod(s).
+You should choose one of the executor types wisely based on the scenario.
 
-Poolmgr watches the controller API and eagerly creates generic pools
-for environments.  It uses Kubernetes deployments to do that.  The
-environment container runs in a pod with the 'fetcher' container.
-Fetcher is a very simple utility that downloads a URL sent to it and
-saves it at a configured location.
+#### PoolManager 
 
-GetFunctionService "specializes" a pod.  The implementation chooses a
-pod from the pool, relabels it to "orphan" the pod from the
-deployment, invokes fetcher to copy the function into the pod, and
-hits the the specialize endpoint on the environment container.  This
-causes the function to be loaded.  The pod is now specific to that
-function.
+PoolManager manages pools of generic containers and function containers.
 
-This function pod is cached; it's cleaned up if it's unused for a few
-minutes.
+PoolManager watches the environment CRD changes and eagerly creates generic pools
+for environments. It uses Kubernetes deployments to do that. The 
+environment container runs in a pod with the 'fetcher' container. 
+Fetcher is a straightforward utility that downloads a URL sent to it 
+and saves it at a configured location (shared volume).
 
-Router
-------
+The implementation chooses a generic pod from the pool, relabels it to
+"orphan". The pod from the deployment invokes fetcher to copy the function 
+into the pod and hits the specialize endpoint on the environment container. 
+This causes the function to be loaded. The pod is now specific to that 
+function. This function pod is cached; it's cleaned up if it's unused for a few minutes.
 
-The router forwards HTTP requests to function pods.  If there's no
-running service for a function, it requests one from poolmgr, while
-holding on to the request; when the function's service is ready it
-forwards the request.
+PoolManager selects a generic pod from the warm pool, specializes it, 
+and recycles the pod if there are no further requests to the function after a few minutes.
+It makes PoolManager suitable for functions that are short-living
+and requires a short cold start time [1].
 
-The router is stateless and can be scaled up if needed, according to
+However, PoolManager only selects one pod per function, which is not
+suitable for serving massive traffic. In such cases, you should consider
+using NewDeploy as executor type of function.
+
+[1] The cold start time depends on the package size of the function. If it's
+a snippet of code, the cold start time usually is less then 100ms.
+
+#### NewDeploy 
+
+NewDeploy creates deployment, service, and HPA for functions in order to handle 
+massive traffic.
+
+NewDeploy watches the function CRD changes and creates a Kubernetes deployment, 
+service, and HPA for a function. NewDeploy will scale the replicas of a function 
+deployment to the minimum feasible scale setting, if the minimum scale setting of 
+a function is greater than 0. The 'fetcher' inside the pod uses a URL in the 
+JSON payload, which is attached as a parameter to start fetcher, to download the 
+function package instead of waiting for calls from NewDeploy. 
+
+When a function experiences a traffic spike, the service helps to distribute the requests to 
+pods belonging to the function for better workload distribution and lower latency. Also, 
+the HPA scales the replicas of the deployment based on the conditions set by the user.
+ 
+This approach though increases the cold time of a function, but also makes NewDeploy 
+suitable for functions designed to serve massive traffic.
+
+### Environment Container
+
+Environment containers run user-defined functions and are language-specific. 
+Each environment container must contain an HTTP server and a loader for functions.
+
+The pool manager deploys the environment container into a pod with fetcher 
+(fetcher is a simple utility that can fetch an HTTP URL to a file at a 
+configured location). This pod forms a "generic pod" because it can
+be loaded with any function in that coding language.
+
+When the pool manager needs to create a service for a function, it calls
+fetcher to fetch the function. Fetcher downloads the function into a
+volume shared between fetcher and this environment container. Poolmgr
+then requests the container to load the function.
+
+### Router
+
+The router forwards HTTP requests to function pods. If there's no
+running service for a function, it requests one from executor, while
+holding on to the request; the router will forward the request to 
+the pod once the function service is ready.
+
+The router is the only stateless component and can be scaled up if needed, according to
 load.
 
-Kubewatcher
------------
+### Builder Manager
+
+The builder manager watches the package & environments CRD changes and manages 
+the builds of function source code. Once an environment that contains a builder 
+image is created, the builder manager will then creates the Kubernetes service 
+and deployment under the fission-builder namespace to start the environment 
+builder. And once a package that contains a source archive is created, the 
+builder manager talks to the environment builder to build the function's source 
+archive into a deploy archive for function deployment.
+
+After the build, the builder manager asks Builder to upload the deploy archive to the 
+Storage Service once the build succeeded, and updates the package status attached with build logs.
+
+### Storage Service
+
+The storage service is the home for all archives of packages with sizes larger than 256KB.
+The Builder pulls the source archive from the storage service and uploads deploy archive to it.
+The fetcher inside the function pod also pulls the deploy archive for function specialization.
+
+## Optional Components
+
+### Logger
+
+Logger is deployed as DaemonSet to help to forward function logs to a centralized 
+database service for log persistence. Currently, only InfluxDB is supported to store logs.
+
+Following is a diagram describe how log service works:
+1. Logger watches pod changes and creates a symlink to the container log if the pod runs on the same node.
+2. Fluentd reads logs from symlink and pipes them to InfluxDB
+3. `fission function logs ...` retrieve event logs from InfluxDB with optional log filter
+4. Logger removes the symlink if the pod no longer exists.
+
+### Kubewatcher
 
 Kubewatcher watches the Kubernetes API and invokes functions
 associated with watches, sending the watch event to the function.
 
-The controller keeps track of user's requested watches and associated
-functions.  Kubewatcher watches the API based on these requests; when

+# BUILDING MULTI-ARCHITECTURE IMAGES
+
+While the Docker images for Fission can be built by running:
+
+```
+make image
+```
+
+the stable images are build for multiple architectures (and automatically pushed to the repository) by
+
+```
+make images-multiarch
+```
+
+However, there are several options and requirements for building these images, which are explained here.
+
+## BUILDERS
+
+We use `docker buildx` to build images for multiple architectures. At the moment, this is considered an
+experimental feature by Docker, and as such it requires access to experimental features to be enabled
+in the daemon.json file.
+
+By default, this will use BuildKit and QEMU emulation support to build the image for each architecture
+locally. However, for faster building, it is possible to use native nodes to build each architecture,
+either simple remote Docker instances or a Kubernetes cluster. For information on how to set this up,
+please see the blog article here:
+
+<https://www.docker.com/blog/multi-arch-images/>
+
+And/or the command reference here:
+
+<https://docs.docker.com/engine/reference/commandline/buildx_create/>
+
+## BUILD OPTIONS
+
+### PLATFORMS
+
+The PLATFORMS variable can be set to a comma-separated list of platforms for which images should be
+built when running the multi-arch build. If unset, it defaults to _linux/amd64,linux/arm64,linux/arm_.
+
+### REPOSITORY SELECTION
+
+By default, the multi-arch build will automatically try to push the resulting images to the fission/*
+repositories, under the dev tag; i.e. fission/fission-bundle:dev, fission/fetcher:dev, and
+fission/builder:dev. However, for convenient, this can be customized by setting the REPO and TAG
+environment variables to set a different repository prefix and tag for the images.
+
+For example:
+
+```
+REPO=randomdev TAG=test make images-multiarch
+```
+
+would build and push the images randomdev/fission-bundle:test, randomdev/fetcher:test, and
+randomdev/builder:test . Private Docker repositories can be used in the same manner.

-Fission Concepts
-----------------
-
-A _function_ is a piece of code that follows the fission function
-interface.
-
-An _environment_ contains the language- and runtime-specific parts of
-running a function.  
-
-The following environments are currently available:
- 
- | Environment                          | Image                     |
- | ------------------------------------ | ------------------------- |
- | Binary (for executables or scripts)  | `fission/binary-env`      |
- | Go                                   | `fission/go-env`          |
- | JVM                                  | `fission/jvm-env`         |
- | .NET                                 | `fission/dotnet-env`      |
- | .NET 2.0                             | `fission/dotnet20-env`    |
- | NodeJS (Alpine)                      | `fission/node-env`        |
- | NodeJS (Debian)                      | `fission/node-env-debian` |
- | Perl                                 | `fission/perl-env`        |
- | PHP 7                                | `fission/php-env`         |

- | Ruby                                 | `fission/ruby-env`        |
-
-You can also extend environments or create entirely new
-ones if you want.  (An environment is essentially just a container
-with a webserver and dynamic loader.)
-
-A _trigger_ is something that maps an event to a function; Fission
-as of today supports [HTTP request](https://docs.fission.io/usage/trigger/#create-a-http-trigger), [timed](https://docs.fission.io/usage/trigger/#create-a-time-trigger), and [message queue](https://docs.fission.io/usage/trigger/#create-a-message-queue-trigger) triggers.

-Usage
------
+## Getting Started
 
 ```bash
-
   # Add the stock NodeJS env to your Fission deployment
   $ fission env create --name nodejs --image fission/node-env
 
-  # A javascript one-liner that prints "hello world"
-  $ curl https://raw.githubusercontent.com/fission/fission/master/examples/nodejs/hello.js > hello.js
-
-  # Upload your function code to fission
-  $ fission function create --name hello --env nodejs --code hello.js
-
-  # Map GET /hello to your new function
-  $ fission route create --method GET --url /hello --function hello
+  # Create a function with a javascript one-liner that prints "hello world"
+  $ fission function create --name hello --env nodejs --code https://raw.githubusercontent.com/fission/examples/master/nodejs/hello.js
 
   # Run the function.  This takes about 100msec the first time.
   $ fission function test --name hello
   Hello, world!

-# Binary Environment Examples
-
-The `binary` runtime is a go server that uses a subprocess to invoke executables or execute shell scripts.
-
-Use Cases
-- Execute bash scripts
-- Execute arbitrary binaries (such as common sysadmin tools)
-- Get support in _any_ programming language by executing the generated executable.
-
-
-⚠️ **Words of Caution** ⚠️
-
-The environment runs on an alpine image with some additional utility commandline tools installed, such as 'grep'. 
-However, in case you want to make use of more esoteric commandline tools, you should add the relevant apk to the 
-Dockerfile and build a new binary environment. See 'Compiling' for instructions.
-
-When executing functions using binaries, **ensure that the executable is built for the right architecture**. 
-Using the default binary environment this means that the binary should be build for Linux.
-
-Looking for ready-to-run examples? See the [binary examples directory](../../examples/binary).
-
-## Usage
-To get started with the latest binary environment:
-
-```bash
-fission env create --name binary --image fission/binary-env --builder fission/binary-builder
-```
-
-The interface to the executable used by this environment is somewhat similar to a [CGI interface](https://en.wikipedia.org/wiki/Common_Gateway_Interface).
-This means that any HTTP headers are converted to environment variables of the form "HTTP_<header-name>". For example these
-are some of frequently occurring headers:
-
-```bash
-# Request Metadata
-CONTENT_LENGTH
-REQUEST_URI
-REQUEST_METHOD
-
-# HTTP Headers
-HTTP_ACCEPT
-HTTP_USER-AGENT
-HTTP_CONTENT-TYPE
-# ...
-```
-
-The body of HTTP piped over the STDIN to the executable. 
-All output that is provided to the server over the STDOUT will be transformed into the HTTP response.
-
-## Compiling
-
-To build the runtime environment:
-```bash
-docker build --tag=${USER}/binary-env .
-```
-
-To build the builder environment:
-```bash
-(cd builder/ && docker build --tag=${USER}/binary-builder .)
-```
