+# Wasm3
+
+[Wasm3](https://github.com/wasm3/wasm3) is a high performance `WebAssembly` interpreter written in C.  
+It's packaged into a `WebAssembly` package, so you can finally run `WebAssembly` on `WebAssembly` 😆
+
+When running natively, wasm3 is:
+
+**∼ 8x faster** than other known wasm interpreters  
+**∼ 4-5x slower** than state of the art wasm `JIT` engines  
+**∼ 12x slower** than native execution  
+
+<sub>Based on [**CoreMark 1.0** benchmark](https://github.com/wasm3/wasm3/blob/master/docs/Performance.md). Your mileage may vary.</sub>
+
+## Running on WebAssembly.sh
+
+First you need to make a wasm file you want to run available in the filesystem.  
+One way to do this is to get it from a server using `curl` command:
+
+```sh
+$ curl https://raw.githubusercontent.com/wasm3/wasm3/master/test/lang/fib32.wasm -o /tmp/fib32.wasm
+
+$ ls -l /tmp/fib32.wasm
+---------- 1 somebody somegroup 62 1970-01-19 05:45 /tmp/fib32.wasm
+```
+
+Now we can run `wasm3` in interactive mode:
+
+```sh
+$ wasm3 --repl /tmp/fib32.wasm
+wasm3> fib 20
+Result: 6765
+wasm3> fib 30
+Result: 832040
+wasm3> ^C
+$
+```
+
+Or run a specific function directly:
+
+```sh
+$ wasm3 --func fib /tmp/fib32.wasm 30
+Result: 832040
+```
+
+`wasm3` also supports `WASI`, so you can run:
+
+```sh
+$ curl https://raw.githubusercontent.com/wasm3/wasm3/master/test/wasi/simple/test.wasm -o /tmp/test.wasm
+$ wasm3 /tmp/test.wasm
+```
+
+or even... run wasm3 inside wasm3:
+
+```sh
+$ curl https://registry-cdn.wapm.io/contents/vshymanskyy/wasm3/0.4.9/build/wasm3-wasi.wasm -o /tmp/wasm3.wasm
+$ wasm3 /tmp/wasm3.wasm /tmp/test.wasm
+```
+
+## Tracing
+
+You can also get structured traces of arbitrary WASM file execution (and this requires no specific support from the runtime):
+
+```sh
+$ wasm3-strace --repl /tmp/fib32.wasm
+wasm3> fib 3
+fib (i32: 3) {
+  fib (i32: 1) {
+  } = 1
+  fib (i32: 2) {
+    fib (i32: 0) {
+    } = 0
+    fib (i32: 1) {
+    } = 1
+  } = 1
+} = 2
+Result: 2
+```
+
+WASI apps tracing is also supported:
+
+```sh
+$ wasm3-strace /tmp/test.wasm trap
+_start () {
+  __wasm_call_ctors () {
+    __wasilibc_populate_preopens () {
+      wasi_snapshot_preview1!fd_prestat_get(3, 65528) { <native> } = 0
+      malloc (i32: 2) {
+        dlmalloc (i32: 2) {
+          sbrk (i32: 0) {
+          } = 131072
+        } = 70016
+      } = 70016
+...
+        strcmp (i32: 70127, i32: 32) {
+        } = 0
+        test_trap () {
+          a () {
+            b () {
+              c () {
+              } !trap = [trap] unreachable executed
+...
