-`std` support for this target relies on newlib. In order to work, newlib must be initialized correctly. The easiest way to achieve this with VITASDK newlib implementation is by compiling your program as a staticlib with and exposing your main function from rust to `_init` function in `crt0`.
-
-Add this to your `Cargo.toml`:
-
-```toml
-[lib]
-crate-type = ["staticlib"]
-
-[profile.release]
-panic = 'abort'
-lto = true
-opt-level = 3
-```
-
-Your entrypoint should look roughly like this, `src/lib.rs`:
-```rust,ignore,no_run
-#[used]
-#[export_name = "_newlib_heap_size_user"]
-pub static _NEWLIB_HEAP_SIZE_USER: u32 = 100 * 1024 * 1024; // Default heap size is only 32mb, increase it to something suitable for your application
-
-#[no_mangle]
-pub extern "C" fn main() {
-    println!("Hello, world!");
-}

-To test your developed rust programs on PlayStation Vita, first you must correctly link and package your rust staticlib. These steps can be preformed using tools available in VITASDK, and can be automated using tools like `cargo-make`.
