+# Overview
+This project is led by a benevolent dictator (PegaSys) and managed by the community. That is, the community actively contributes to the day-to-day maintenance of the project, but the general strategic line is drawn by the benevolent dictator. In case of disagreement, they have the last word. It is the benevolent dictator’s job to resolve disputes within the community and to ensure that the project is able to progress in a coordinated way. In turn, it is the community’s job to guide the decisions of the benevolent dictator through active engagement and contribution.
+
+
+# Principles

+The community adheres to the following principles:
+* Open: EthSigner is open source. See repository guidelines and CLA, below.
+* Welcoming and respectful: See Code of Conduct, below.
+* Transparent and accessible: Work and collaboration should be done in public. 
+* Merit: Ideas and contributions are accepted according to their technical merit and alignment with project objectives and design principles.
