 ### Setup Your Machine Configuration File
 
-Follow the instructions in [[Machine Configuration File | Installation:-Machine-Configuration-File]] to set the configuration file of your machine.
+The machine configuration file is located under `configs`. This file contains the library paths, compiler types, compilation flags, and GPU compute capability. Check the existing configuration files to see if one matches your machine.
+
+If no suitable configuration file is available, you will need to create a new one. Follow the instructions in [[Machine Configuration File | Installation:-Machine-Configuration-File]] to set up a configuration file for your machine.
+
+If a configuration file matches your machine, you can set it as the default by running
+
+```bash
+sh tool/config/set_settings.sh --local --machine=your_machine
+```
+
+For example, setting `--machine=pleiades` with the above command will use the `configs/pleiades.config` machine configuration when compiling the code.
