adding squid web proxy to click as package to CLICK

Hello all,

I would want to add squid web proxy as a packages ( I feel adding as
package would be much simpler than adding it as element) to click, I
fallowed /etc/samplepackage which gives very brief information on how to
add and build our own package to click.
I would want to go in depth on adding packages to click.
please can anybody provide me the document which explains how to add
packages to click in detail( Note:I am not good at programming :( :( . )

Thanks so much.
