+- `type:` The section type. `code`, `data`, `rodata` or `bss`.
+- `align:` The section alignment in bytes.
+- `vaddr:` (REL only) The fixed virtual address of the section. When set, split and symbol addresses are written as absolute addresses.

 - `rename:` Writes this section under a different name when generating the split object. Used for `.ctors$10`, etc.
 - `common` Only valid for `.bss`. See [Common BSS](common_bss.md).
 - `skip` Skips this data when writing the object file. Used for ignoring data that's linker-generated.

-#### `Sections:` header (REL modules only)
-
-REL modules can specify fixed virtual addresses for sections using a `Sections:` block at the top of the file. This is useful for projects where REL modules load at known addresses, allowing symbols and splits to use absolute addresses instead of section-relative ones.
