+# Brainfk -> WASM
+## Introduction
+This repo contains a brainfk compiler written in Rust which compiles code directly to wasm. Later the generated wasm file can be ran using wasmer.
+### Install Wasmer Runtime
+Follow this link to install wasmer-runtime
+https://docs.wasmer.io/ecosystem/wasmer/getting-started
+
+### Example
+```shell
+$ cargo run
+    Finished dev [unoptimized + debuginfo] target(s) in 0.01s
+     Running `target/debug/brainfk-rs`
+error: The following required arguments were not provided:
+    --target <TARGET>
+    <INPUT_FILE>
+    <OUTPUT_FILE>
+
+USAGE:
+    brainfk-rs --target <TARGET> <INPUT_FILE> <OUTPUT_FILE>
+
+For more information try --help
+
+$ cargo run -- tests/files/hello.f hello.wasm --target wasi
+   Compiling brainfk-rs v0.1.0 (/root/Documents/brainfk-rs)
+    Finished dev [unoptimized + debuginfo] target(s) in 0.91s
+     Running `target/debug/brainfk-rs tests/files/hello.f abc.wasm --target wasi`
+
+$ wasmer run hello.wasm
+Hello World!
