-**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
-```
-
-### `fx infra use`
-
-To use a infrastructure, you can use `fx infra use` command to activate it.
-
-```shell
-fx infra use <infrastructure name>
-```
-

+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
+...
+```
