+# 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.

-##### Build and Run
+# 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
 
 ```
-fx up ./examples/functions/func.js
+NAME:
+   fx - makes function as a service
+
+USAGE:
+   fx [global options] command [command options] [arguments...]
+
+COMMANDS:
+   up        deploy a function
+   down      destroy a service
+   list, ls  list deployed services
+   image     manage image of service
+   help, h   Shows a list of commands or help for one command
+
+GLOBAL OPTIONS:
+   --help, -h     show help
+   --version, -v  print the version
 ```
 
-the function defined in *examples/functions/func.js* is quite simple, it calculates the sum of two numbers then returns:
+### Deploy function
+
+#### Local Docker environment
+
+By default, function will be deployed on localhost， 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.
+
 ```
-module.exports = (input) => {
-    return parseInt(input.a, 10) + parseInt(input.b, 10)
-}
+$ fx up --name hello ./examples/functions/JavaScript/func.js
+
++------------------------------------------------------------------+-----------+---------------+
+|                                ID                                |   NAME    |   ENDPOINT    |

++------------------------------------------------------------------+-----------+---------------+
 ```
 
+#### Remote host
+
+Use `--host` to specify the target host for your function, or you can just set it to `FX_HOST` environment variable.
+
+```shell
+$ fx up --host roo@<your host> --name hello ./examples/functions/JavaScript/func.js
+
++------------------------------------------------------------------+-----------+---------------+
+|                                ID                                |   NAME    |   ENDPOINT    |
++------------------------------------------------------------------+-----------+---------------+
+| 5b24d36608ee392c937a61a530805f74551ddec304aea3aca2ffa0fabcf98cf3 | /hello    | 0.0.0.0:58345 |
++------------------------------------------------------------------+-----------+---------------+
+```
+
+#### Kubernetes
+
+```
+$ FX_KUBECONF=~/.kube/config fx up examples/functions/JavaScript/func.js --name hello
+
++-------------------------------+------+----------------+
+| ID                     | NAME        |    ENDPOINT    |
++----+--------------------------+-----------------------+
+|  5b24d36608ee392c937a  | hello-fx    | 10.0.242.75:80 |
++------------------------+-------------+----------------+
+```
+
+### Test service
+
 then you can test your service:
-```
-curl -X POST <service url> -H "Content-Type: application/json" -d '{"a": 1, "b": 1}'
+
+```shell
+$ curl -v 0.0.0.0:58328
+
+
+GET / HTTP/1.1
+Accept: */*
+Accept-Encoding: gzip, deflate
+Connection: keep-alive
+Host: 0.0.0.0:10001
+User-Agent: HTTPie/1.0.2
+
+
+
+HTTP/1.1 200 OK
+Connection: keep-alive
+Content-Length: 11
+Content-Type: text/plain; charset=utf-8
+Date: Sat, 10 Aug 2019 05:28:03 GMT
+
+hello world
+
 ```
 
-of course you can do more.
-```
-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)
+## 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>
 ```
 
-#### How to write your function
+Then you can verify it with `kubectl`,
 
-functions example with Go, Ruby, Python, Node, PHP.
+```shell
+$ kubectl get nodes
 
-* 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
-}
+NAME                       STATUS   ROLES   AGE     VERSION
+aks-nodepool1-31718369-0   Ready    agent   6m44s   v1.12.8
 ```
 
-* Ruby
-```
-def fx(input)
-    return input['a'] + input['b']
-end
+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 FX_KUBECONF=~/.kube/config  # then fx will take the config to deloy function
 ```
 
-* Python
-```
-def 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>
 ```
 
-* Node
-```
-module.exports = (input) => {
-    return parseInt(input.a, 10) + parseInt(input.b, 10)
-}
+Then make sure you current context is GKE cluster, you can check it with command,
+
+``` shell
+$ kubectl config current-context
 ```
 
-* PHP
-```
-<?php
-    function Fx($input) {
-        return $input["a"]+$input["b"];
-    }
+Then you can deploy your function onto GKE cluster with,
+
+```shell
+$ FX_KUBECONF=~/.kube/config fx up examples/functions/JavaScript/func.js --name hellojs
 ```
 
-* Julia
-```
-struct Input
-    a::Number
-    b::Number
-end
+* Setup your own Kubernetes cluster
 
-fx = function(input::Input)
-    return input.a + input.b
-end
+```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'
 ```

+The only thing `fx` does is to make a single function to be an HTTP service, `fx` takes two steps to finish the process,
+* Wraps the function into a web server project and make it be the handler function of the HTTP request.
+* Builds the bundled web server to be Docker image, then run it as a Docker container and expose the service port.
+
+`bundler` is the component responsible for step 1: wrap a single function (and its dependencies) into a web server.  Take a Node web service as an example, the project looks like this,
+```
+helloworld
+├── Dockerfile
+├── app.js
+└── fx.js
+```
+
+And the codes is pretty simple,
+
+**app.js**
+```javascript
+const Koa = require('koa');
+const bodyParser = require('koa-bodyparser');
+const cors = require('@koa/cors');
+const fx = require('./fx');
+
+const app = new Koa();
+app.use(cors({
+  origin: '*',
+}));
+app.use(bodyParser());
+app.use(fx);
+
+app.listen(3000);
+```
+
+**fx.js**
+```javascript
+module.exports = (ctx) => {
+  ctx.body = 'hello world'
+}
+```
+
+**Dockerfile**
+```dockerfile
+FROM metrue/fx-node-base
+
+COPY . .
+EXPOSE 3000
+CMD ["node", "app.js"]
+```
+
+You can see that it's a web service built with `Koa`,  the request handler function defined in `fx.js` to response plain text `hello world`,  so to make a general JavaScript/Node function to be a web service, we only have to put it into `fx.js` above, then build and run it with Docker and that's it.
+
+To support different programming languages, `fx` needs to implement different `bundlers`, the reasons are,
+* The way to set up a web service is different in different languages
+* The way to manage dependency is different in different languages.
+
+So there will be (are) different `bundlers` in `fx`.
+```
+go-bundler: based on Gin
+ruby-bundler: based on Sinatra
+node-bundler: based on Koa
+python-bundler: based on flask
+...
+```
