+Building Mac OS binaries
+========================
+
+This guide explains how to build Electrum binaries for macOS systems.
+We build our binaries on El Capitan (10.11.6) as building it on High Sierra
+makes the binaries incompatible with older versions.
+
+
+## 1. Run the script
+
+
+
+    ./make_osx
+
+## 2. Done
+
+Hopefully it will be that simple.
