More clear installation steps

[ov7a]

Please, make a more clear instructions to installation. Not everyone knows where to get rustup.
It also would be nice to have binary releases/deb/rpm packages.

Prebuilt binary releases are indeed useful.
We do have Docker images now: https://hub.docker.com/r/fede1024/kafka-view/

Once rust nightly has been installed, the rest of the install can skip a few steps with:

cargo +nightly install --git https://github.com/fede1024/kafka-view.git

...having said that, I notice that it needs resources directory when it runs so the build doesn't include that in the binary and the suggestion above is fairly pointless because you still need to pull down the git repo separately.

I've added a pull request to fix the issue immediately above: #34
