+The default options are:
+
+```javascript
+options: {
+  inDir: '.',
+  outDir: 'doc',
+  onlyUpdated: false,
+  colourScheme: 'default',
+  ignoreHidden: false,
+  sidebarState: true,
+  exclude: false,

+  css: [],
+  extras: []
+}

+
+The options provided above are the defaults configured in [Docker](https://github.com/jbt/docker) and
+correspond to its CLI.
+
 Then just run `grunt docker` and enjoy!
 
-By default, Grunt Docker will use `src = "."` and `dest = "doc"` if they are not
-provided. `dest` will be given to Docker through the `options.outDir` option and
-`src` is used in the call to the doc generation as an `Array`.
+## Notes on output directory
+
+Docker itself doesn't quite follow Grunt convention, choosing to instead specify an `outDir`.
+If you need to output to more than one directory, define a new task; unfortunately, a single
+Docker object is allocated per-task and can only be used for a single output folder.
+
+Grunt-Docker will figure out the correct `outDir` property by reading Grunt's interpretation of
+`files.dest`. In most cases, this works fine. If you are having issues with relative paths, use 
+`options.outDir`, instead of `files.dest`.
+
+If your source files are above the current working directory (starting with `../), you *must* change
+`options.inDir`, or your docs will end up in the same folder as the source folders. For example, if
+my `src` property were `../../src/**/*.js`, I would set `options.inDir` to `'../../'.
 
-The options provided there are the defaults configured in [Docker](https://github.com/jbt/docker) and
-corresponds to the command line arguments that are possible to use.
+By default, Grunt-Docker will use `files.src = "."` and `options.outDir = "doc"` if they are not
+provided. `src` is used in the call to the doc generation as an `Array`.
