 This command reads the input Wasm file, removes WASI dependencies, and reroutes WASI calls to their IC-specific 
 implementations. Note that the polyfill implementation must be present in your Wasm binary.
 
-To include the polyfill implementation in your Canister project, add the ic-wasi-polyfill dependency to your project.
+To include the polyfill implementation in your Canister project, add the ic-wasi-polyfill dependency in it:
+```bash
+cargo add ic-wasi-polyfill
+```
+
+Also you will need to add the initialization call to the polyfill library, basic example using memory manager:
+
+```rust
+use ic_stable_structures::{memory_manager::MemoryManager, DefaultMemoryImpl};
+use std::cell::RefCell;
+
+thread_local! {
+    // The memory manager enables multiple virtual memories in one.
+    static MEMORY_MANAGER: RefCell<MemoryManager<DefaultMemoryImpl>> =
+        RefCell::new(MemoryManager::init(DefaultMemoryImpl::default()));
+}
+
+#[ic_cdk::init]
+fn init() {
+    MEMORY_MANAGER.with(|m| {
+        let m = m.borrow();
+        ic_wasi_polyfill::init_with_memory_manager(&[0u8; 32], &[], &m, 200..210);
+    });
+}
+```
