Installation instructions

[slondr]

Hi, could installation instructions be added to the docs?

I'm not sure how to install. I guessed that maybe I should (ql:quickload :sento), but that gave me some errors:

; caught ERROR:
;   READ error during COMPILE-FILE:
;   
;     Lock on package SB-C violated when interning LAMBDA-PARENT while in package
;     LOG4CL-IMPL.
;   See also:
;     The SBCL Manual, Node "Package Locks"
;   
;     (in form starting at line: 99, column: 0, position: 3779)
