New to psychological network analysis? Looking for an overview of the literature, or tutorials on how to estimate network models? This site contains a list of introduction and tutorial papers, articles, and blog posts. If you know of other good resources, please let me know so I can update the page.

#### Workshop materials

- The best starting point to pick up both network theory and network methodology are the workshops and summer/winter schools we have been giving. Materials for the last 5-day winter school in Amsterdam 2019 are available on the Open Science Framework. Materials for the international 1 to 3-day workshops we have been giving in the last few years are also available online for free.
