How to add these additional packages?

[teeedubb]

Hi Guys,
First off, thanks for your work in putting these addons together... there's some real useful apps in there.
Not an issue as such, but how can I add some packages to openwrt?
Sorry if this has been covered somewhere, but I'm a openwrt noob and couldn't find anything about it on the net.
Thanks in advance.

What I have done so far is add the git address as a feed and then update feeds. After that I can see the new packages inside the menuconfig.
