 # Implementation Notes
@@ -34,9 +27,11 @@ bb64 runs the command by replacing the current process, so it ensures that tty,
 variables etc are all identical for the run command. It works with interactive commands, like
 nano or ssh.
 
-bb64 supports bash scripts, as the command is run as:
-    `bash -c 'COMMAND'`
+The command is run as:
+    `bash -c COMMAND`
 Where COMMAND is passed to bash as a single argument.
 
 If the command is run, the return value is the return value of the command.
 If it isn't run, bb64 returns -1.
+
+`./build.sh` will build bb64 for x86_64 (amd64) and arm64 architectures.
