+## Goals
+
+The Seedcase Project is more than software: It is also about education,
+training, and the code itself.
+
+### Develop open-source software for health data
+
+Software that is open-source and targeted to diverse users, like health
+research organizations and small-to-medium sized companies.
+
+### Create training material and run workshops
+
+Specifically training on technical skills such as software and data
+engineering, while following open scientific practices.
+
+### Build and nurture an inclusive community
+
+A community that is open and inclusive that shares knowledge, learnings,
+and better practices in research data engineering and software
+engineering.
+
+### Lead by example
+
+By building this project as fully open as possible and applying the same
+principles we teach and advocate for.
