+#/      Music sequencer and audio editor.
+#/      Experimental, work in progress.
 #/
 #/  ----------------------------------------------------------------
 #/
+#/  Qualities
+#/
+#/  - Single source file
+#/  - All dependencies are included with the code
+#/  - No configuration required
+#/  - Cross-platform thanks to sokol and miniaudio
+#/
+#/    NOTE
+#/    You can build the project easily using this two commands:
+#/    > gcc -o buildme -DBUILDME saw.c
+#/    > ./buildme
+#/    Or, on Windows, with MSVC compiler:
+#/    > cl.exe -Febuildme.exe -DBUILDME saw.c
