-#### Build scripts
-This is the non-prefered way of building a release, it's use is discouraged and it will be soon deprecated in favour of
-using the builder crate.
-
-To package a release with the generated ffi header and CMake module, use the `build-profiling-ffi.sh` / `build-telemetry-ffi.sh` helper scripts.
-Here's an example of using on of these scripts, placing the output inside `/opt/libdatadog`:
-
-```bash
-bash build-profiling-ffi.sh /opt/libdatadog
-```
-
 #### Build dependencies
 
 - Rust 1.84.1 or newer with cargo. See the Cargo.toml for information about bumping this version.
