-* `target/debug` is the same size as `target` - so we know nearly all the disk usage of the 1.5G is in this folder
-* `target/debug/deps` this is 1.2G - Note the bar jumps down to 70% to indicate that most disk usage is here but not all.

 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
-
+- du -d 1 -h | sort -h
 
+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.
