+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at H.Minghe@gmail.com. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

+
+# Installation
+
+Binaries are available for Windows, MacOS and Linux/Unix on x86. For other architectures and platforms, follow instructions to [build fx from source](#buildtest).
+
+* MacOS
 
 ```
-$ git clone https://github.com/metrue/fx.git
-$ cd fx
-$ dep ensure
-$ go install ./
+brew tap metrue/homebrew-fx
+brew install metrue/fx/fx
 ```
 
-* start server
+* Linux/Unix
 
-```
-fx serve
+via cURL
+
+```shell
+# Install to local directory
+curl -o- https://raw.githubusercontent.com/metrue/fx/master/scripts/install.sh | bash
+
+# Install to /usr/local/bin/
+curl -o- https://raw.githubusercontent.com/metrue/fx/master/scripts/install.sh | sudo bash
 ```
 
-now you can make a function to service in a second.
+fx will be installed into /usr/local/bin, sometimes you may need `source ~/.zshrc` or `source ~/.bashrc` to make fx available in `$PATH`.
+
+* Windows
+
+You can go the release page to [download](https://github.com/metrue/fx/releases) fx manually;
+
+## Usage
+
+Make sure [Docker](https://docs.docker.com/engine/installation/) installed and running on your server first. then type `fx -h` on your terminal to check out basic help.
 
 ```
-fx up ./examples/functions/func.js

-Usage:
-$ fx serve                                      start f(x) server
-$ fx up   func1.js func2.py func3.go ...        deploy a function or a group of functions
-$ fx down [service ID] ...                      destroy a function or a group of functions
-$ fx list                                       list deployed services
-$ fx --version                                  show current version of f(x)
+## Manage Infrastructure
+
+**fx** is originally designed to turn a function into a runnable Docker container in a easiest way, on a host with Docker running, you can just deploy your function with `fx up` command,  and now **fx** supports deploy function to be a service onto Kubernetes cluster infrasture, and we encourage you to do that other than on bare Docker environment, there are lots of advantage to run your function on Kubernetes like self-healing, load balancing, easy horizontal scaling, etc. It's pretty simple to deploy your function onto Kubernetes with **fx**, you just set KUBECONFIG in your enviroment.
+
+By default. **fx** use localhost as target infrastructure to run your service, and you can also setup your remote virtual machines as **fx**'s infrastructure and deploy your functions onto it.
+
+### `fx infra create`
+
+You can create types (docker and k8s) of infrastructures for **fx** to deploy functions
+
+```shell
+$ fx infra create --name infra_us --type docker --host <user>@<ip>                                            ## create docker type infrasture on <ip>
+$ fx infra create --name infra_bj --type k8s --master <user>@<ip> --agents '<user1>@<ip1>,<user2>@<ip2>'      ## create k8s type infrasture use <ip> as master node, and <ip1> and <ip2> as agents nodes
 ```
 
-#### How to write your function
+### `fx infra use`
 
-functions example with Go, Ruby, Python, Node, PHP.
+To use a infrastructure, you can use `fx infra use` command to activate it.
 
-* Go
-```
-package main
-
-type Input struct {
-	A int32
-	B int32
-}
-
-type Output struct {
-	Sum int32
-}
-
-func Fx(input *Input) (output *Output) {
-	output = &Output{
-		Sum: input.A + input.B,
-	}
-	return
-}
+```shell
+fx infra use <infrastructure name>
 ```
 
-* Ruby
-```
-def fx(input)
-    return input['a'] + input['b']
-end
+and you can list your infrastructure with `fx infra list`
+
+## Use Public Cloud Kubernetes Service as infrastructure to run your functions
+
+* Azure Kubernetes Service (AKS)
+
+You should create a Kubernetes cluster if you don't have one on AKS, detail document can found [here](https://docs.microsoft.com/en-us/azure/aks/kubernetes-walkthrough).
+
+```shell
+$ az group create --name <myResourceGroup> --location eastus
+$ az aks create --resource-group <myResourceGroup> --name myAKSCluster --node-count <count>
+$ az aks get-credentials --resource-group <myResourceGroup> --name <myAKSCluster>
 ```
 
-* Python
-```
-def fx(input):
-    return input['a'] + input['b']
+Then you can verify it with `kubectl`,
+
+```shell
+$ kubectl get nodes
+
+NAME                       STATUS   ROLES   AGE     VERSION
+aks-nodepool1-31718369-0   Ready    agent   6m44s   v1.12.8
 ```
 
-* Node
-```
-module.exports = (input) => {
-    return parseInt(input.a, 10) + parseInt(input.b, 10)
-}
+Since AKS's config will be merged into `~/.kube/config` and set to be current context after you run `az aks get-credentials` command, so you can just set KUBECONFIG to default config also,
+
+```shell
+$ export KUBECONFIG=~/.kube/config  # then fx will take the config to deloy function
 ```
 
-* PHP
-```
-<?php
-    function Fx($input) {
-        return $input["a"]+$input["b"];
-    }
+But we would suggest you run `kubectl config current-context` to check if the current context is what you want.
+
+* Amazon Elastic Kubernetes Service (EKS)
+  TODO
+
+* Google Kubernetes Engine (GKE)
+
+First you should create a Kubernetes cluster in your GKE, then make sure your KUBECONFIG is ready in `~/.kube/config`, if not, you can run following commands,
+
+``` shell
+$ gcloud auth login
+$ gcloud container clusters get-credentials <your cluster> --zone <zone> --project <project>
 ```
 
-* Julia
-```
-struct Input
-    a::Number
-    b::Number
-end
+Then make sure you current context is GKE cluster, you can check it with command,
 
-fx = function(input::Input)
-    return input.a + input.b
-end
+``` shell
+$ kubectl config current-context
 ```
 
-### Contributors
+Then you can deploy your function onto GKE cluster with,
+
+```shell
+$ KUBECONFIG=~/.kube/config fx up examples/functions/JavaScript/func.js --name hellojs
+```
+
+* Setup your own Kubernetes cluster
+
+```shell
+fx infra create --type k3s --name fx-cluster-1 --master root@123.11.2.3 --agents 'root@1.1.1.1,root@2.2.2.2'
+```
+
