+### What is PIISA?
+We are Canadian Non-Profit that spawend from the BigScience Piracy Working Group. PIISA stands for a Personally Identifiable Information Standard Architecture. This open source and interoperableframework creates a standard designed to allow seamless interoperability between various PII processing frameworks.
 
-Edit this `README.md` markdown file to author your organization card.
+### Rationale
+Our mission statement stems from these facts:
+
+Proper PII management is hard, and has many facets.
+
+There are solutions available for PII processing, both open source and commercial
+
+We might want to combine several solutions to achieve better results, or to adapt to specific use cases
+
+However there is no practical way of achieving such combination, or of customizing solutions
+
+Our approach has been let's define an architecture that decomposes the PII problem into blocks, and let's define interfaces between those blocks
+
+Therefore the PIISA specification, and its reference implementation, tries to follow the approach of independent components that pass data between them to compose a full solution
