Can someone elaborate on Cygwin instructions (step 9)

[Vano2000]

i don't understand what these step require me to do:

9)Cygwin uses a special way of accessing the normal windows filesystem. If, for example, you placed the OpenTTD source code at C:\openttd\, Cygwin sees that as /cygdrive/c/openttd/.
+Alternatively, if you got subversion - launch cygwin and run mkdir -p /usr/src/openttd to make the directory, then cd /usr/src/openttd and finally svn checkout svn://svn.openttd.org/trunk. This will place all the source code in /usr/src/openttd/trunk
+You can always get the latest source code by running command: svn update.

especially this parts: "mkdir -p /usr/src/openttd", "cd /usr/src/openttd","svn checkout svn://svn.openttd.org/trunk". Where are those directories comming from and how do i know which one i have???

thx in advance

You know you have the directory/ies because you just created it/them.

If you didn't create them, you don't have them.

Comprehension is useful, but not required, for following those directions. Just type what they say to type, and everything will work.
