Zoya,
We're excited to hear that you are interested in contributing to Fedora, and happy to point you in the right direction.
Most relevant to the Outreachy position listed would be tasks related to the Hubs project itself. You can find the hubs repository at the URL here:
You can then run the following from the command-line:
git fetch
git checkout develop
There's also a tutorial in that README about 'Stubbing out a new widget' - follow those steps too.
After you've done those tasks, we have a list of widgets that need to be created under the "issue" tab on the pagure.io page. When you're ready to take a try at that, let us know and we can help you figure out a good one to start out with.
We will usually respond within 1-24 hours if you stay connected to IRC. I would recommend you hang out in #fedora-outreachy as much as possible, as well as join other channels like #fedora-apps (general infra/web development channel) and #fedora-hubs (hubs specific web development) so you can get a feel for who is active in the community, and how everyone gets things done.
If you have any questions, just reply here, or ask in channel (threebean and/or decause should be able to help on freenode.)
Hope this helps,
--RemyD.
