Thanks StefanPuntNL and wennes. Fixes #5.

-The usage of these scripts should be relatively straight forward. If you want more details, please refer to the corresponding blog post: https://blog.yrden.de/2014/11/14/remote-control-bravia-tvs-with-authentication.html
+## Setup
+
+You need to set your TV to use a pre-shared key.
+
+1. Navigate to: [Settings] → [Network] → [Home Network Setup] → [IP Control]
+2. Set [Authentication] to [Normal and Pre-Shared Key]
+3. There should be a new menu entry [Pre-Shared Key]. Set it to **0000**. If you choose anything else, you need to change the PSK in the `send_command.sh` script.
+
+## Usage
+
+1. Run `print_ircc_codes.sh TV_IP_HERE` to get an overview of the commands possible.
+2. Run `send_command.sh TV_IP_HERE ONE_COMMAND_HERE`. A command looks like `AAAAAQAAAAEAAABgAw==`.
+3. The TV will execute the command and immediately return. If you want to navigate through menus, you'll have to manually `sleep` until the TV has finished the command/animation.
+
+See `example_goto_media_player.sh` on how to build your automations.
+
+Have fun!

+### More detailed explanation

+The original blog post describes how to figure this out in general:

+
+StefanPuntNL figured out how to use it with a Pre-Shared-Key, which is much simpler:
