Add instructions for configuring for the Eww bar

Why would we use markdown in the Emacs world, right?

-# org-clock-waybar – Export the currently clocked-in task to be displayed on Waybar
-
-## Installation
-
-Put `org-clock-waybar.el` somewhere in your `load-path`, and `(require 'org-clock-waybar)`.
-
-MELPA version may come soon.
-
-You can set the file to be written by customizing `org-clock-waybar-filename`; it defaults to
-`$XDG_CACHE_HOME/waybar-current-task.json` (`$XDG_CACHE_HOME` defaults to `$HOME/.cache` on XDG
-compatible systems, like Linux.)
-
-### Quelpa
-
-If you only have [`quelpa`](https://github.com/quelpa/quelpa) installed:
-
-```elisp
-(quelpa
- '(org-clock-waybar
-   :fetcher git
-   :url "https://gitea.polonkai.eu/gergely/org-clock-waybar.git"))
-```
-
-or, if you have [`quelpa-use-package`](https://github.com/quelpa/quelpa-use-package) installed,
-too:
-
-```elisp
-(quelpa-use-package org-clock-waybar
-  :quelpa (org-clock-waybar
-           :fetcher git
-           :url "https://gitea.polonkai.eu/gergely/org-clock-waybar.git"))
-```
-
-## Waybar configuration
-
-To add the current task to Waybar, add this snippet to your config:
-
-```json
-"custom/org": {
-  "format": " {}",
-  "return-type": "json",
-  "restart-interval": 5,
-  "exec": "cat /home/yourusername/.cache/waybar-current-task.json"
-}
-```
-
-Then, add `custom/org` to `modules-left`/`modules-center`/`module-right` if your bar’s
-configuration.  You can find a minimal working configuration in the [`examples`](./examples)
-directory.
-
-### Additional Configuration
-
-You can also display an icon specific to the clocked tasks category with the `format-icons` key:
-
-```json
-"custom/org": {
-    "format": "{icon} {}",
-    "return-type": "json",
-    "restart-interval": 1,
-    "format-icons": {
-      "refile": "",
-      "ToDo": "",
-    },
-  "exec": "cat /home/yourusername/.cache/waybar-current-task.json"
-}
-```
-
-If you use Emacs as a daemon (e.g. starting it as `emacs --daemon` or calling `(server-start)`),
-you can change the `exec` command to invoke `emacsclient` directly.  Note that, since Emacsclient
-can’t actually write stuff to the terminal, it will output an Emacs string full of backslashes
-(see [this Emacs SE answer for details](https://emacs.stackexchange.com/a/28668/507)); thus, you
-have to pipe the output through `jq fromjson`.
-
-If you run emacs in this mode you can also eval commands on click, middle click or scroll.:
-
-```json
-"custom/org": {
-    "format": "{icon} {}",
-    "return-type": "json",
-    "restart-interval": 1,
-    "format-icons": {
-      "refile": "",
-      "ToDo": "",
-    },
-    "exec": "emacsclient --eval '(org-clock-waybar-ouptut-task)' | jq fromjson --unbuffered --compact-output",
-    "on-click": "emacsclient --eval '(org-clock-out)'",
-    "on-middle-click": "emacsclient --eval '(org-clock-in-last)'",
-},
-
-```
-
-If you want the taskbar to show nothing or some other content if the emacs server is not running then you need to write a short bash script to catch when the emacsclient command returns a non-zero exit code. An example of this is:
-
-```bash
-#!/bin/bash
-
-json=$(emacsclient --eval '(org-clock-waybar-ouptut-task)' 2> /dev/null)
-status=$?
-[ $status -eq 0 ] && echo $(echo $json | jq fromjson --unbuffered --compact-output) || echo ""
-```
-
-## Customization
-
-To see a list of configurable parts, use `M-x customize-group <RET> org-clock-waybar`.
