+## Prerequisites
+
+The code is designed to run on Linux. Also ensure that `iptables` and `libnetfilter-queue1` packages are installed:
+
+```sh
+$ apt-get install iptables libnetfilter-queue1
+```
+
+Modify your iptables:
+
+```sh
+$ iptables -A OUTPUT -p tcp --sport 8080 -j NFQUEUE --queue-num 0
+$ iptables -A INPUT -p tcp --dport 8080 -j NFQUEUE --queue-num 0
+$ iptables -A INPUT -p icmp --icmp-type time-exceeded -j NFQUEUE --queue-num 0
+```
+
+```sh
+$ iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
+```
+
+## Compiling
+
+Compilation requires the `netfilter-queue-dev` package and Go 1.8 or later.
+
+```sh
+$ apt-get install netfilter-queue-dev
+$ go build
+```
+
+## Running
+
+To start listening on port 8080:
+
+```sh
+$ ./tracetrout
+```
