+The Bitcoin Operations Technology Group (Optech) works to bring the best
+open source technologies and techniques to Bitcoin-using businesses in
+order to lower costs and improve customer experiences.
+
+An initial focus for the group is working with its member organizations to
+reduce transaction sizes and minimize the effect of subsequent transaction fee
+increases.
+
+Long-term goals include providing documentation and training materials, a
+weekly newsletter, original research, and facilitating improved relations
+between businesses and the open source community.
+
+Optech does not exist to make a profit, and all materials and documentation
+produced are placed in the public domain. We are supported by our generous
+founding sponsors and contributions from member companies.
+
+If you're an engineer or manager at a Bitcoin company or an open source contributor and you'd like to be a part of this, please
