Steps to make encfs work on Debian GNU/Linux

Compile or install a kernel with support for FUSE (found in `make menuconfig` under Filesystems).

sudo apt-get install fuse-utils
sudo vigr && sudo vigr -s # add yourself to the fuse group
su - `whoamì` # alternatively you can logout and login again
              # to update your group
mkdir $HOME/.crypt $HOME/crypt
encfs $HOME/.crypt $HOME/crypt

Answer the questions (pass phrase etc), go with default settings in most cases.

DONE!
