+## 2. Setting it up
 
 plexupdate.sh looks for a file named `.plexupdate` located in your home directory. Please note that I'm referring to the home directory of the user who is running the plexupdate.sh ... If that user is someone else (root for instance) you'll need to make sure that user has the config file set up properly as well.

 Obviously you need to change these three so they match your account information. And if you don't put anything as a `DOWNLOADDIR`, the tool will use the folder you're executing the script from. So take care.

 You can point out a different file than ```.plexupdate``` by providing it as the last argument to the script. It HAS to be the LAST argument, or it will be ignored. Any options set by the config file can be overriden with commandline options.

 Starting today, the ```-C``` option is deprecated and will give an error to check the docs. The new version is ```-c``` and will make sure that only fatal errors are reported back via the exit code. No more 2, 3, 4 or 5 exitcodes. They are converted into 0. Combining this option with ```-q``` will hide any and all non-essential output from the script as well. Only error messages are emitted, so if it fails, you'll know why.

 I'm going to be lazy, just run the tool with `-h` and you'll find out what you can do. It will basically be a mirror of what section 3 just stated :-)

+# Running it
 
 It's very simple, just execute the tool once configured. It will complain if you've forgotten to set it up. If you want to use the autoinstall (-a option or `AUTOINSTALL=YES` is set), you must run as root or use sudo when executing or plexupdate.sh will stop and give you an error.
 
 Overall it tries to give you hints regarding why it isn't doing what you expected it to.
