In order to get access to certain tweaks, themes, and other jailbreak downloads you may need to add a source, also known as a repository in Cydia.

To add a source it is quite simple and can be done by following the steps below -

1. Enter Cydia
2. Go to the Manage tab
3. Select sources
4. Select edit in the upper right corner
5. Select add in the upper left corner
6. Type the repo URL in the box. Be sure to have all neccessary text such as “http:// .com and so on”
7. Once the repo is fully typed out correctly hit add source

The source is now added to Cydia on your device. Contents in the repo can be found by going to manage and then sources, or you can simply use the search tab to browse all Cydia contents including contents from that repo.
