 Installing
 ----------
-
-0. Install Anki. The currently supported version range is 2.1.1〜2.1.11, with the
-   exception of 2.1.9<sup id="readme-fn-01b">[1](#readme-fn-01)</sup>. (Keep in
-   mind this range only applies to the Anki used by the server, clients can be
-   as old as 2.0.27 and still work.) Running the server with other versions might
-   work as long as they're not 2.0.x, but things might break, so do it at your
-   own risk. If for some reason you can't get the supported Anki version easily
-   on your system, you can use `anki-bundled` from this repo:
-
-        $ git submodule update --init
-        $ cd anki-bundled
-        $ pip install -r requirements.txt
-
-   Keep in mind `pyaudio`, a dependency of Anki, requires development headers for
-   Python 3 and PortAudio to be present before running `pip`. If you can't or
-   don't want to install these, you can try [patching Anki](#running-ankisyncd-without-pyaudio).

 1. Install the dependencies:

-        $ python -m ankisyncd
+    Webob does not support the header "Transfer-Encoding: chunked" used by Anki
+    and therefore ankisyncd sees chunked requests as empty. To solve this problem
+    setup Nginx (or any other webserver of your choice) and configure it to
+    "unchunk" the requests for ankisyncd.
 
----
+    For example, if you use Nginx  on the same machine as ankisyncd, you first
+    have to change the port in `ankisyncd.conf` to something other than `27701`.
+    Then configure Nginx to listen on port `27701` and forward the unchunked
+    requests to ankisyncd.
+
+    An example configuration with ankisyncd running on the same machine as Nginx
+    and listening on port `27702` may look like:
