1) if you don't have gpg key, you should generate one:

vmiklos@vmhome:~$ gpg --gen-key

2) you should export it:

vmiklos@vmhome:~$ gpg --export "yourmailaddress" > /tmp/gpg.key

then send your gpg.key to the frugalware-devel list

(i write here how i import them as i always forgot it ;)
gpg --keyring /var/lib/darcs/repos/frugalware-test/allowed_keys --no-default-keyring --import /home/vmiklos/upload/foo.gpg.key )

3) after you have write access get the reposithory:

vmiklos@vmhome:~$ darcs get http://darcs.frugalware.org/repos/frugalware-test/
vmiklos@vmhome:~$ cd frugalware-test/

4) make some changes (such as add a new line to foobar.c, etc)

5) see what has been modified:

vmiklos@vmhome:~/frugalware-test$ darcs whatsnew

4) set your preferences (name and email address; automatically sign patches)

vmiklos@vmhome:~/frugalware-test$ echo "VMiklos <mamajom@axelero.hu>" >_darcs/prefs/author

vmiklos@vmhome:~/frugalware-test$ echo "send sign" >_darcs/prefs/defaults

5) record your changes (locally)

vmiklos@vmhome:~/frugalware-test$ darcs record
hunk ./foobar.c 4
+/* vmiklos from vmhome at 20010108-1721 */
