Getting Started


You can find the docs here. Documentation is generated with jazzy and hosted on GitHub-Pages.

To regenerate docs, run ./scripts/build_docs.sh from the root directory in the repo.


For the long-term goals and "vision" of IGListKit, please read our Vision doc.


Please see the CONTRIBUTING file for how to help. At Instagram, we sync the open source version of IGListKit daily, so we're always testing the latest changes. But that requires all changes be thoroughly tested and follow our style guide.

We have a set of starter tasks that are great for beginners to jump in on and start contributing.


IGListKit is BSD-licensed. We also provide an additional patent grant.
