+You'll need to [download Go](https://golang.org/dl/) check the code out somewhere, run 'go generate' and then 'go build'.
 
 ## Using it
 
-`dau` is a command line driven program. When executed, it will continually scan a directory for new images, and each time it finds one it will upload it to discord, via the discord web hook.
+`dau` configuration is managed via its internal web interface. When the executable is run, you can visit
+`http://localhost:9090` in your web browser to configure the it. Configuration persists across runs, it is
+saved in a file called '.dau.json' in your home directory.
+
+The first time you run it, you will need to configure at least the discord web hook and the watch path for
+`dau` to be useful.
+
+While running, `dau` will continually scan a directory for new images, and each time it finds one it will upload it to discord, via the discord web hook.
 
 `dau` will only upload "new" screenshots, where "new" means a file that appears in a directory that it is watching, if it appears *after* it has started executing.
 
 Thus, you do not have to worry about pointing `dau` at a directory full of images, it will only upload new ones.
 
-If `dau` is on your path, you can run it from your screenshot folder and there is then no need to specify the path to your images.
+## Configuration options
 
-The only two mandatory command line parameters are the discord webhook URL:
+See the web interface at http://localhost:9090 to configure `dau`.
 
-`--webhook URL` - the webhook URL (see [here](https://support.discordapp.com/hc/en-us/articles/228383668-Intro-to-Webhooks) for details).
+### 'Discord WebHook URL'
 
-and the directory to watch:
+The webhook URL from Discord. See https://support.discordapp.com/hc/en-us/articles/228383668-Intro-to-Webhooks
+for more information on setting one up.
 
-`--directory /some/path/here` - the directory that screenshots will appear in.
+### 'Bot Username'
 
-You will have to quote the path on windows, or anywhere where the directory path contains spaces. Note that
+This is completely optional and can be any arbitrary string. It makes the upload
-subdirectories will also be scanned.
+appear to come from a different user (though this is visual only, and does not
+actually hide the bot identity in any way). You might like to set it to your own
+discord name.
 
-Other parameters are:
+### 'Directory to watch'
 
-`--watch xx` - specify how many seconds to wait between scanning the directory. The default is 10 seconds.
+This is the path that `dau` will periodically inspect, looking for new images.
+Note that subdirectories are also scanned. You need to enter the full filesystem
+path here.
 
-`--username <username>` - an arbitrary string to show as the bot's username in the channel.
+### 'Period between filesystem checks'
 
-`--no-watermark` - don't watermark images with a reference to this tool.
+This is the number of seconds between which `dau` will look for new images.
 
-`--help` - show command line help.
+### 'Do not watermark images'
 
-`--version` - show the version.
+This will disable the watermarking of images. I like it when you don't set this :-)
+
+### 'Files to exclude'
+
+This is a string to match against the filename to check for exclusions. The common
+use case is to use 'thumbnail' or similar if your image directory contains additional
+thumbnail files.
 
 ## Limitations/bugs
 
 * Only files ending jpg, gif or png are uploaded.
 * If multiple screenshots occur quickly (<1 second apart) not all may be uploaded.
+* Files to upload are determined by the file modification time. If you drag and drop existing files they will
+  not be detected and uploaded. Only newly created files will be detected.
+
+## Troubleshooting
+
+Please check the "log" page on the web interface for information when things are
+not working as you expect.
 
 ## TODO
-This is just a quick hack. Open to suggestions on new features and improvements.
