well if you're hosting from your computer, you would need to do some port forwarding so that when someone tries to access your IP it would redirect them to your web server.
I'm pretty bad at explaining things myself so try this, maybe it'll help you.
Assuming that you have already packed the config into the patcher, and uploaded the required web files to your website, the next thing do is create a new data folder consisting of only the files that you would want to patch.
For example, you want to update the scr_logo.bmp (logo at the lower right of screenshots), your new data folder should look like this.
data/texture/scr_logo.bmp
Open ThorGenerator.exe (<thor directory>/Tools/ThorGenerator.exe), and follow these instructions:
Upload the generated .thor file to whatever you specified as `file_url` in your config.ini, example http://yourwebsite.com/patch/data/ then in your plist.txt (http://yourwebsite.com/patch/plist.txt) add the filename of your new patch. DO NOT include the comments example:
