+
+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.
+
+```
+$ fx up --name hello ./examples/functions/JavaScript/func.js

++------------------------------------------------------------------+-----------+---------------+
+```
+
+#### 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 infra ls     # list machines
+$ fx up --host roo@<your host> --name hello ./examples/functions/JavaScript/func.js

-It may take seconds since `fx` needs to download some basic resources
-
-*Note* you can add a remote host as fx machine also,
-```
-$ fx infra add --name my_aws_vm --host 13.121.202.227 --user root --password yourpassword
-
-$ fx infra list

-}
-
-$ fx infra activate my_aws_vm

-```
-then your function will be deployed onto remote host also.
-
-2. Write a function
-
-You can check out [examples](https://github.com/metrue/fx/tree/master/examples/functions) for reference. Let's write a function as an example,  it calculates the sum of two numbers then returns:
-
-```js
-module.exports = (ctx) => {
-    ctx.body = 'hello world'
-}
-```
-Then save it to a file `func.js`.
-
-3. Deploy your function as a service
-
-Give your service a port with `--port`, and name with `--name`, heath checking with `--healthcheck` if you want.
-
-```shell
-$ fx up -name fx_service_name -p 10001 --healthcheck func.js

++------------------------------------------------------------------+-----------+---------------+
 ```
 
-if you want see what the source code of your service looks like, you can export it into a dirctory,

+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
+...
