 The different colors on the bars: These represent the combined tree hierarchy & disk usage. The shades of grey are used to indicate which parent folder a subfolder belongs to. For instance, look at the above screenshot. `.steam` is a folder taking 44% of the space. From the `.steam` bar is a light grey line that goes up. All these folders are inside `.steam` so if you delete `.steam` all that stuff will be gone too.

+## Why to use Dust over the Alternatives
+
+Dust simply Does The Right Thing when handling lots of small files & directories. Dust keeps the output simple by only showing large entries.
+
+Tools like ncdu & baobab, give you a view of directory sizes but you have no idea where the largest files are. For example directory A could have a size larger than directory B, but in fact the largest file is in B and not A. Finding this out via these other tools is not trivial whereas Dust will show the large file clearly in the tree hierarchy 
+
+Dust will not count hard links multiple times (unless you want to `-s`).
+
+Typing `dust -n 90` will show you your 90 largest entries. `-n` is not quite like `head -n` or `tail -n`, dust is intelligent and chooses the largest entries
+
 
-Note: Apparent-size is calculated slightly differently in dust to gdu. In dust each hard link is counted as using file_length space. In gdu only the first entry is counted.
