+# Netwide Assembler
+
+This is the netwide assembler and it is meant to be used in the binary compatibility mode of unikraft.
+
+## Content
+- sample_code.s: a sample assembly code file that can be assembled using nasm.
+- usr/bin/nasm: the nasm binary
+- lib/ & lib64/: the required libraries for nasm
+
+## Extract dynamic libraries
+```../extract.sh usr/bin/nasm```
+
+output:
+```
+Copying /lib/x86_64-linux-gnu/libc.so.6 ...
+Copying /lib64/ld-linux-x86-64.so.2 ...
+```
+
+## Run on linux
+```nasm sample_code.s```
+
+## Run on unikraft
+```./run.sh -r ../dynamic-apps/nasm/ usr/bin/nasm sample_code.s```
+
+This should generate the output file ```sample_code``` which is the assembled machine code generated by nasm.
