sourceforge sites

[shekofte]

Hi masters
my 1th post
i hope my problem solves at this forum !
this is the first time in my life that i want to setup a site !

now i activated this site on sourceforge :
http://coin.sourceforge.net/

i am going to design my custom webpage and replace it with the default sourceforge's page !
like this sample sites :
http://audacity.sourceforge.net/
http://tenebrae.sourceforge.net/
http://flea.sourceforge.net/

but i realy confused about it , even by reading this guide :
https://sourceforge.net/apps/trac/sourceforge/wiki/Project%20web
what is the meaning of this instruction ? (a section of the guide) :

Quick Start Guide for Project Web

What's that you say, you want to just get to it? Use one of our supported protocols like SFTP, SCP, or rsync to upload your files:

[jsmith@linux ~]$ sftp jsmith,fooproject@web.sourceforge.net
Connecting to web.sourceforge.net...
The authenticity of host 'web.sourceforge.net (216.34.181.57)' can't be established.
RSA key fingerprint is 68:b3:26:02:a0:07:e4:78:d4:ec:7f:2f:6a:4d:32:c5.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'web.sourceforge.net,216.34.181.57' (RSA) to the list of known hosts.
jsmith,fooproject@web.sourceforge.net's password:
sftp> cd htdocs
sftp> put index.html
Uploading index.html to /home/groups/f/fo/fooproject/htdocs/index.html
index.html 100% 241 0.2KB/s 00:01
sftp> exit

what is the first step ?

please a gentleman disabuse me , this is a memorial donation for me !
