 ### __Overlay__
-More Text
+For use with Overlays you need to include the related header file. You must place this include into the Namespace of your overlay to avoid name clash. Now the `lba` array is accessible.
+
+```c++
+namespace Overlay {
+    #include <PSX/Overlay/overlay_declaration.hpp>
+    
+    // ...
+    printf("LBA: %i, Words: %i\n", lba[LBA::SYSTEM_CNF].lba, lba[LBA::SYSTEM_CNF].size_words);
+    // ...
+
+    __declare_overlay_header(execute, LBA);
+}
+```
 
 ### __Main file__
-Text
+For use with the main file you need to include the header file and use the `__declare_lba_header` macro with the name of your enum to create the LBA area in any file. The header allows to access the `lba` array with your enum as the index.

+```
+
+## For CD generation
+To automatically fill the LBA values `psxcdgen_ex` needs to be used.
+
+For the main file the special XML type `Main` needs to be used while specifing the LBA file being used.
+
+For Overlays the instruction will follow...
+
+```xml
+<Track>
+  <File name="SYSTEM.CNF">System.cnf</File>
+    <Main name="SCES_XXX.XX" lba_source="main.cpp">Application.psexe</Main>
+</Track>
