+# PySCF Virtual Seminar Series
+
+The **PySCF Virtual Seminar Series** is a monthly forum where PySCF developers can present, share, and advertise new or ongoing implementations across the PySCF software suite. The seminar is **open to everyone**, join live via **Zoom** meeting (there won't be any recording of the talk), and if you'd like calendar invites so you don't miss a talk, please fill out the **[Google Form](https://forms.gle/Potn9vEzK4r5EBqu9)**. If you’re interested in presenting in a future session, you can submit the [form](https://forms.gle/Potn9vEzK4r5EBqu9).
