How do I change the default startup directory in Cygwin?

Whenever I start cygwin, I need to cd several levels down to the only directory that I care about when using cygwin.

How can I get cygwin to start in this particular directory by default...i.e., each time I start Cygwin it will be in that directory already?

I found some things that may be it, or close, but I don't understand them, and there's really no results when I search for these (n00b) terms. Any help would be great!

Just add

cd /path/to/directory/you/care/about

to the bottom of your ~/.bashrc file.

in the last line of your .bash_profile (or .profile), put cd your/dirctory/here
