+# vcl-ldpreload a LD_PRELOAD library that uses the VPP Communications Library (VCL).
+
+User can LD_PRELOAD any application that uses POSIX socket API.
+This library internally uses libvppcom.so library from VPP project.
+
+
+## HowTo
+
+If VPP is not installed, but rather built in a separate directory, you can use the VPP_DIR 'configure' argument.
+```bash
+# 1. Set environment variables for source
+cd vpp/extras/vcl-ldpreload
+source ./env.sh
+
+# 2. Change to VPP source directory and build
+- Change director and modify uri.am to enable socket_test program
+
+cd $VPP_DIR
+perl -pi -e 's/noinst_PROGRAMS/bin_PROGRAMS/g' $VPP_DIR/src/uri.am
+
+- Build VPP release
+
+make install-dep wipe-release bootstrap dpdk-install-dev build-release
+
+# 2. Build LD_PRELOAD library against VPP build above
+## This does not install the LD_PRELOAD library in your system.
+## Instead it will be referenced from the build directory set in VCL_LDPRELOAD_LIB
+
+cd $LDP_DIR/vcl-ldpreload/src
+autoreconf -i -f
+./configure VPP_DIR=$VPP_DIR
+make
+```bash
+
+
+# 3. Running the demo
+## Run test script without parameters to see help menu:
+
+cd $VPP_DIR/test/scripts
+./socket_test.sh
+
+# 4. Docker iPerf examples.
+## These launch xterms. To quit, close xterms and run following docker kill cmd (WARNING: This will kill all docker containers!) 'docker kill $(docker ps -q)'
+
+
+## Docker iPerf using default Linux Bridge
+
+./socket_test.sh -bi docker-kernel
+
+## Docker iPerf using VPP
+./socket_test.sh -bi docker-preload
+
