-`omitSourceMapUrl` is a `Boolean` flag to determine whether to include `sourceMappingURL` comment in the output file.
-
 #### sourceMap
-If your `sourceComments` option is set to `map`, `sourceMap` allows setting a new path context for the referenced Sass files.
-The source map describes a path from your CSS file location, into the the folder where the Sass files are located. In most occasions this will work out-of-the-box but, in some cases, you may need to set a different output.
+`sourceMap` can be set as `String` or `Boolean`. If it is set to `true`, the path of sourceMap would be computed by node-sass w.r.t the outFile path. It can also be set to absolute or relative (to outFile) path.

-### Edge-case behaviours
+The stats object consists of the following constituents:
 
-* In the case that both `file` and `data` options are set, node-sass will only attempt to honour the `file` directive.
+```javascript
+{
+    entry: "path/to/entry.scss",    // or just "data" if the source was not a file
+    start: 10000000,                // Date.now() before the compilation
+    end:   10000001,                // Date.now() after the compilation
+    duration: 1,                    // end - start
+    includedFiles: [ ... ],         // absolute paths to all related scss files
+    sourceMap: "..."                // the source map string or null
+}
+```
 
+Note: `includedFiles` isn't sorted in any meaningful way, it's just a list of all imported scss files including the entry.
 
+### Sepecial behaviours
+
+* In the case that both `file` and `data` options are set, node-sass will give precedence to `data` and use `file` to calculate paths in sourcemaps.
+
+### Version information (v2 change)
+
+Both `node-sass` and `libsass` version info is now present in `package.json` and is expoded via `info()` method:
+
+```javascript
+require('node-sass').info();
+
+// outputs something like:
+// node-sass version: 2.0.0-beta
+// libsass version: 3.1.0-beta
