 ## Definition
 
-<tt>GB_debugger_execute_command([[GB_gameboy_t]] *gb, char *input);</code>
+<tt>void GB_debugger_execute_command([[GB_gameboy_t]] *gb, char *input);</code>
 
 In `debugger.h`
 
 ## Description
 
-TBD
+Executes a debugger command `input` in an emulator instance, and returns its (potentially formatted) output via the [[logging interface|GB_set_log_callback]].
+
+The contents of `input` are destroyed upon returning from this function.
 
 ## Thread Safety
 
 `GB_debugger_execute_command` must not be called if the instance is being run in another thread, but may be called from the current one (via a callback).
+
+## Notes
+
+Some flow-control commands, such as `continue` and `step`, are not supported by this function and may not behave as expected.
