+[[eupf_setup]]
+== eupf setup
+
+[[eupf_install]]
+=== eupf install
+
+#Install eupf dependencies:
+----
+sudo apt install wget git clang llvm gcc-multilib libbpf-dev
+----
+
+Download eupf:
+----
+$ mkdir $HOME/git
+$ cd $HOME/git
+$ git clone https://github.com/edgecomllc/eupf.git
+----
+
+Install swag:
+----
+$ cd $HOME
+go install github.com/swaggo/swag/cmd/swag@v1.8.12
+----
+
+Add to .bashrc:
+----
+export PATH="${HOME}/go/bin:/usr/local/go/bin:${PATH}"
+----
+
+Build & install eupf:
+----
+$ cd ~/git/eupf
+$ go generate -v ./cmd/...
+$ go build -v -o bin/eupf ./cmd/
+$ sudo cp bin/eupf /usr/local/bin/eupf
+----
+
+[[eupf_debug]]
+=== eupf debug
+
+To enable XDP tracing, recompile like this:
+----
+$ cd ~/git/eupf
+$ BPF_CFLAGS="-DENABLE_LOG" go generate -v ./cmd/...
+$ go build -v -o bin/eupf ./cmd/
+$ sudo cp bin/eupf /usr/local/bin/eupf
+----
+
+Then start eupf, run the test, cat will keep reading until killed, and you'll get output generated by the xdp code:
+----
+$ cat /sys/kernel/debug/tracing/trace_pipe
+----
