+## Description
+
+`gowipe` is a simple self contained tool to securely wipe files and
+directories. By default it renames and overwrites files and
+directories 30 times and uses the `secure` mode, which uses strong
+random bytes for the overwriting process. Gowipe writes as much bytes
+into a file as its original size.
+
+You can tweak mode and round numbers. Other modes are `zero`, which
+uses zeroes for overwriting (not recommended) or `encrypt` which
+encrypts the data using AES and a strong random key. This is the most
+secure but also to slowest mode.
+
+Although you can use `gowipe` on SSD disks, it doesn't make much
+sense. To wipe such a disk you have to resort to other means. But you
+can savely use it on magnetic discs or usb drives.
+
+Of course there are many other such tools available, this one is
+insofar special as you can download a pre-compiled binary without any
+library dependencies. This allows you to wipe files on systems, where
+you cannot install a wiper via some package management (such as
+appliance systems or vm's).
+
+## Example
+
+Overwrite the directory `vhs` recursively 50 times using strong
+encryption and verbose output:
+
+```shell
+gowipe  -c 50 -E -r -v vhs
+Wiped vhs/help.png (355011 bytes)
+Wiped vhs/rec.Dockerfile (348 bytes)
+Wiped vhs/rec.gif (3533338 bytes)
+Wiped vhs/rec.tape (852 bytes)
+Wiped vhs (4096 bytes)
+
+   Dirs wiped: 1
+  Files wiped: 5
+Bytes deleted: 3889549
+ Time elapsed: 426.286639ms
+  Overwritten: 50 times
+    Wipe mode: encrypt
+ Recurse dirs: true
