+Inner Source is a strategy to frictionless cross-team collaboration in software development inside an organization. 
+Based on Open Source methodologies, it provides an adaptable set of tools and practices for contributing to code 
+developed by other teams. By fostering transparency and openness, it lowers the hurdle to get involved into 
+decision-making throughout the corporation.
+
+Core principles of Inner Source include:
+- openness: all artifacts developed by an organization should be available to all employees
+- active contribution: developers are encouraged to rather implement a feature instead of asking for it
+- written communication: all decisions should be comprehensible and transparent
+- rewards and motivation: every contribution is important and deserves recognition
+
+As AOE strives for a high involvement of every employee into decision processes and organizational development, Inner
+Source seems an ideal fit to our [company culture](https://www.aoe.com/en/career/how-we-work.html).
