 ## Getting started
 
-### Linux
+### Binaries
 
-* Download this script:
+TBD
 
-`curl -O https://raw.githubusercontent.com/tardisx/discord-auto-upload/master/dau`
+#### From source
 
-* Put it somewhere on your path (if you want to be able to run it from anywhere)
+TBD
-* chmod +x it
-* Install the dependencies:
-
-CPAN: `cpan install Mojolicious IO::Socket::SSL`
-
-CPANM: `cpanm Mojolicious IO::Socket::SSL`
-
-Ubuntu/Debian: `sudo apt-get install libmojolicious-perl libio-socket-ssl-perl`
-
-* test it:
-
-`dau --help`
-
-### Mac
-
-Basically the same as Linux above. [Perlbrew](https://perlbrew.pl) is highly recommended so as not to disturb the system perl. No need for superuser access then either.
-
-### Windows
-
-* Grab the windows exe file:
-
-`http://tba`
-
-* Optional, put it somewhere on your path
-* Open a command prompt
-* Test it
-
-`\some\path\dau --help`
-
-If you want to hack it, audit it, or don't trust my exe, you can install
-[Strawberry Perl](http://strawberryperl.com) and run it using that directly.
-You'll need the same dependencies mentioned above in the Linux setup.

 Note that currently `dau` does not look in subdirectories. Please submit an issue if this is a use case for you.
 
-The only mandatory command line parameter is the discord webhook URL:
+The only two mandatory command line parameters are the discord webhook URL:
 
 `--webhook URL` - the webhook URL (see [here](https://support.discordapp.com/hc/en-us/articles/228383668-Intro-to-Webhooks) for details).
 
+and the directory to watch:
+
+`--directory /some/path/here` - the directory that screenshots will appear in.
+
+You will have to quote the path on windows, or anywhere where the directory path contains spaces.
+
 Other parameters are:
 
 `--watch xx` - specify how many seconds to wait between scanning the directory. The default is 10 seconds.
 
-`--directory <somedir>` - the directory to watch for images to appear in. If this option is not supplied, will look in the current directory.
-
-You will have to quote the path on windows, or anywhere where the directory path contains spaces.
-
-`--username` - supply a 'username' with the webhook submission. Slightly misleading, it basically provides some extra text next to the "Bot" display on the upload to the channel.
-
-In the example screenshot, this was set to "tardisx uploaded from EDD".
-
-`--debug` - provide extra debugging.
-
 ## Limitations/bugs
 
 * Only files ending jpg, gif or png are uploaded.
-* Subdirectories are not scanned.
 * If multiple screenshots occur quickly (<1 second apart) not all may be uploaded.
