 ### Creating a Single Header File
 
-If you want to generate one header file you will need to run the `./scripts/create_single_header.sh`.
-
 It requires you have `cargo` installed from rust. See these instructions if you don't have that https://www.rust-lang.org/tools/install.
 It uses the https://github.com/Felerius/cpp-amalgamate crate to do the single header file creation.
 
 The output will be generated in the `build/single_header/libdbc/` folder. You can run a cmake command to build this as well as other targets.
 
+To just build the single header you can simply run the target:
+```shell
+cmake -Bbuild -H. -DDBC_GENERATE_SINGLE_HEADER=ON
+
+cmake --build build --parallel `nproc` --target single-header
+```

 ## Testing
 
 I am trying to always make sure that this is very well tested code. I am using Catch2 to do this
