+Rust library with type definitions and parsing functions for Multiboot2 headers,
+as well as a builder to build them at runtime. This library is `no_std` and can
+be used in bootloaders.
 
 What this library is good for:
-- writing a small binary which writes you a valid Multiboot2 header
-  into a file (such as `header.bin`)
+- construct a Multiboot2 header at runtime (constructing one at build-time with
+  macros is not done yet, contributions are welcome!)
+- write a Multiboot2-bootloader that parses a Multiboot2-header
 - understanding Multiboot2 headers better
 - analyze Multiboot2 headers at runtime
 
-What this library is not optimal for:
-- compiling a Multiboot2 header statically into an object file using only Rust code
-
 ## Features and `no_std` Compatibility
+
 This library is always `no_std` without `alloc`. However, the default `builder`-
 feature requires the `alloc`-crate and an `#[global_allocator]` to be available.
 You need the `builder` only if you want to construct new headers at runtime.
-For parsing, this is not relevant, and you can deactivate the default feature.

 ## Example 2: Multiboot2 header as static data in Rust file
+
 You can use the builder, construct a Multiboot2 header, write it to a file and include it like this:
 ```
 #[used]
 #[no_mangle]
 #[link_section = ".text.multiboot2_header"]
-static MULTIBOOT2_HDR: &[u8; 64] = include_bytes!("mb2_hdr_dump.bin");
+static MULTIBOOT2_HDR: [u8; 64] = include_bytes!("mb2_hdr_dump.bin");
 ```
 You may need a special linker script to place this in a LOAD segment with a file offset with less than 32768 bytes.
 See specification.
