+# button
+
+This repository contains code for solving [button.qedaka.de](https://button.qedaka.de). The goal of the game is to
+press a button as many times as possible. To verify the button has actually been pressed, a "proof of work" has to be
+provided. There are eight challenges in total – each of which uses a different kind of "proof of work":
+- [01_welcome](./js/01_welcome.js)
+- [02_these_numbers_are_big](./js/02_these_numbers_are_big.js)
+- [03_are_you_still_doing_this_by_hand](./js/03_are_you_still_doing_this_by_hand.js)
+- [04_broken_proof_of_work](./js/04_broken_proof_of_work.js)
+- [05_what_the_bf](./js/05_what_the_bf.js)
+- [06_automation_is_not_enough](./js/06_automation_is_not_enough.js)
+- [07_weird_assembly_machine](./js/07_weird_assembly_machine.js)
+- [08_revisit_everything](./js/08_revisit_everything.js)
+
+Challenges one through four are trivial to solve. For challenges five through eight there is one binary each which
+demonstrates an approach to a solution.
+
+One additional binary for solving the whole game from start to finish is provided.
