 RPC that, when enabled, logs the location and duration of each lock contention
 to the `debug.log` file.
 
-To enable it, run configure with `-DDEBUG_LOCKCONTENTION` added to your
-CPPFLAGS, e.g. `CPPFLAGS="-DDEBUG_LOCKCONTENTION"`, then build and run dashd.
+The `--enable-debug` configure option adds `-DDEBUG_LOCKCONTENTION` to the
+compiler flags. You may also enable it manually for a non-debug build by running
+configure with `-DDEBUG_LOCKCONTENTION` added to your CPPFLAGS,
+i.e. `CPPFLAGS="-DDEBUG_LOCKCONTENTION"`, then build and run dashd.
 
 You can then use the `-debug=lock` configuration option at dashd startup or
 `dash-cli logging '["lock"]'` at runtime to turn on lock contention logging.
