-## HTTPie: cURL for humans
-
-HTTPie is a CLI frontend for [python-requests](http://python-requests.org) built out of frustration. It provides an `http` command that can be used to easily issue HTTP requests. It is meant to be used by humans to interact with HTTP-based APIs and web servers. The response headers are colorized and the body is syntax-highlighed if its `Content-Type` is known to [Pygments](http://pygments.org/) (unless the output is redirected).
-
-![httpie](https://github.com/jkbr/httpie/raw/master/httpie.png)
-
-
-### Installation
-
-    pip install httpie
-
-
-### Usage
-
-    http [flags] METHOD URL [header:value | data-field-name=value]*
-
-The default request `Content-Type` is `application/json` and data fields are automatically serialized as a JSON `Object`, so this:
-
-    http PATCH api.example.com/person/1 X-API-Token:123 name=John email=john@example.org
-
-Will issue the following request:
-
-    PATCH /person/1 HTTP/1.1
-    User-Agent: HTTPie/0.1
-    X-API-Token: 123
-    Content-Type: application/json; charset=utf-8
-
-    {"name": "John", "email": "john@example.org"}
-
-You can use the `--form` flag to set `Content-Type` and serialize the data as `application/x-www-form-urlencoded`.
-
-The data to be sent can also be passed via `stdin`:
-
-    http PUT api.example.com/person/1 X-API-Token:123 < person.json
-
-Most of the flags mirror the arguments you would use with `requests.request`. See `http -h`:
-
-    $ http -h
-    usage: http [-h] [--json | --form] [--traceback] [--ugly] [--headers | --body]
-                [--auth AUTH] [--verify VERIFY] [--proxy PROXY]
-                [--allow-redirects] [--file PATH] [--timeout TIMEOUT]
-                method URL [item [item ...]]
-
-    HTTPie - cURL for humans.
-
-    positional arguments:
-      method                HTTP method to be used for the request (GET, POST,
-                            PUT, DELETE, PATCH, ...).
-      URL                   Protocol defaults to http:// if the URL does not
-                            include it.
-      item                  HTTP header (key:value) or data field (key=value)
-
-    optional arguments:
-      -h, --help            show this help message and exit
-      --json, -j            Serialize data items as a JSON object and set Content-
-                            Type to application/json, if not specified.
-      --form, -f            Serialize data items as form values and set Content-
-                            Type to application/x-www-form-urlencoded, if not
-                            specified.
-      --traceback           Print a full exception traceback should one be raised
-                            by `requests`.
-      --ugly, -u            Do not prettify the response.
-      --headers, -t         Print only the response headers.
-      --body, -b            Print only the response body.
-      --auth AUTH, -a AUTH  username:password
-      --verify VERIFY       Set to "yes" to check the host's SSL certificate. You
-                            can also pass the path to a CA_BUNDLE file for private
-                            certs. You can also set the REQUESTS_CA_BUNDLE
-                            environment variable.
-      --proxy PROXY         String mapping protocol to the URL of the proxy (e.g.
-                            http:foo.bar:3128).
-      --allow-redirects     Set this flag if full redirects are allowed (e.g. re-
-                            POST-ing of data at new ``Location``)
-      --file PATH           File to multipart upload
-      --timeout TIMEOUT     Float describes the timeout of the request (Use
-                            socket.setdefaulttimeout() as fallback).
