+`wasm-opt -O {{input.wasm}} -o {{output.wasm}}`
+
+- Apply all optimizations and write to a given file (takes more time, but generates optimal code):
+
+`wasm-opt -O4 {{input.wasm}} -o {{output.wasm}}`
+
+- Optimize a file for size:
+
+`wasm-opt -Oz {{input.wasm}} -o {{output.wasm}}`
+
+- Print the textual representation of the binary to console:
+
+`wasm-opt {{input.wasm}} --print`
