add docs

[dnut]

splitting out this work from #32 which is for the implementation of other mime-types, because these docs shouldn't take as long.

add to the docs:

• clear explanation of exactly which mime types are supported (currently only text)
• uninstall instructions, including the exact commands to cleanly remove everything from debian-based distros (I'll need to test that this really cleans things out properly without screwing anything up)

Ubuntu & Debian

Install from the official repository:

Using Wget :

sudo wget \
  -P /etc/apt/sources.list.d/ \
  https://raw.githubusercontent.com/dnut/deb/master/dnut.list
sudo apt-get update \
  && sudo apt-get install clipboard-sync

Using cUrl :

sudo curl \
  -sL https://raw.githubusercontent.com/dnut/deb/master/dnut.list \
  -o /etc/apt/sources.list.d/dnut.list
sudo apt-get update \
  && sudo apt-get install clipboard-sync

Uninstall from repository

sudo apt-get purge clipboard-sync \
&& sudo rm /etc/apt/sources.list.d/dnut.list

How about this?
I dont know if purge will suffice, and no any other residual files need to be deleted.
And I prefer apt-get command because on platform supporting apt mostly support apt-get but not otherwise.

Edit:
I add installation command with cUrl for people with platform that only have curl and no wget, and separate options per-line so it's easy to overview the command.

I also want to add usage command for background process using simple & and dedicated screen command for option without service.
(just a reminder when I'm coming back to this)

Features

1. Auto Discovery

   Automatically sync among numbers of display without mentioning display number.

2. Mime Types Support
   

• Full Text (text utf8)
• Images (png, jpg, jpeg)

What about features section?
I dont know what kind of text we are supporting, assuming utf8 which support arabic, chinese and other texts.

I also want to add my use case in docs, like ...

---

Example use cases:

• Multiple Workspaces with custom startup programs and window positions
  Use Xephyr to manage true workspaces with hand-picked programs and well positioned window layout for each display, since linux 'workspaces' arent facilitating to startup default programs and window locations. By launching multiple X displays with Xephyr and clipboard-sync to enable copy paste among workspaces.

---

Edit :
Simple question or dedicated issue

Is it possible to support drag and drop with this program? For example, I drag picture or text to Xephyr window
or it just out of scope of 'clipboard-sync'?

@mrtugicom

Thanks so much for your contributions, and sorry for the slow response. I work on clipboard-sync in my spare time, and my spare time has taken a hit lately due to some dramatic increases in my job-related workload. This is still on my radar, and I plan to address it soon. I would like to carefully review this information and test any changes before publishing anything. You are also welcome to open a PR if you want.

I don't expect this to work because I don't think drag and drop uses the clipboard behind the scenes. It may be worth some investigation after other issues are addressed, but I don't have high hopes for it being easy to support something like this.
