+# 1.5. Setup Erlang Environment
+
+First we need to install Erlang. There is multiple way, for development we will
+be using *ASDF*, a tool that allows the installation of multiple version of Erlang
+at the same time, and switch from one version to the other at will.
+
+
+## 1.5.1. Setup Erlang using asdf
+
+First, install any missing dependencies:
+
+    sudo apt install curl git autoconf libncurses-dev build-essential m4 libssl-dev 
+
+Download *ASDF* tool to the local account:
+
+    git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.10.2
+
+Make *ASDF* activate on login by adding these lines at the end of the `~/.bashrc` file:
+
+    . $HOME/.asdf/asdf.sh
+    . $HOME/.asdf/completions/asdf.bash
+
+Logout and log back in to activate *ASDF*.
+
+*ASDF* supports multiple tools by installing there corresponding plugins.
+Install *ASDF* plugin for Erlang:
+
+    asdf plugin add erlang https://github.com/asdf-vm/asdf-erlang.git
+
+Install a version of Erlang:
+
+    asdf install erlang 24.3.4.2
+
+Activate Erlang locally for TFS controller. This will create a local file
+called `.tool-versions` defining which version of the tools to use when
+running under the current directory:
+
+    cd tfs-ctrl/
+    asdf local erlang 24.3.4.2
+
+Erlang projects uses a build tool called rebar3. It is used to manager project
+dependenecies, compile a project and generate project releases.
+Install rebar3 localy from source:
+
+    cd ~
+    git clone https://github.com/erlang/rebar3.git
+    cd rebar3
+    asdf local erlang 24.3.4.2
+    ./bootstrap
+    ./rebar3 local install
+
+Update `~/.bashrc` to use rebar3 by adding this line at the end:
+
+    export PATH=$HOME/.cache/rebar3/bin:$PATH
+
+Logout and log back in.

+
+### Setup NetGen
+
+    $ sudo apt update
+    $ sudo apt-get install git ruby ruby-dev tmux gettext-base
+    $ mkdir -p ~/testbed
+    $ cd ~/testbed
+    $ git clone git@github.com:sylane/netgen.git
+    $ cd netgen
+    $ git checkout teraflow
+    $ sudo gem install bundler:1.15
+    $ bundle _1.15_ install
+
+
+### Run the Test-Bed
+
+First load the [teraflow configuration file](~/tfs-ctrl/src/te/tests/topology-descriptors.json) using the webui.
+
+In first console:
+    $ cd ~/testbed
+    $ ../tfs-ctrl/src/te/tests/start-testbed.sh
+
+Then in second console:
+    $ sudo -i
+    # cd /tmp/negen
+    # ./tmux.sh
+
+Be sure that both PCC connected to the TE service before going further.
+This can be done by looking at the TE service log:
+
+    $ kubectl --namespace tfs logs $(kubectl --namespace tfs get pods --selector=app=teservice -o name) -c server
+
+### Setup a flow from the Erlang console
+
+We will setup two unidirectional flow between router 1 and 6.
+We will use the binding label 1111 for the flow from router 1 to router 6, and the binding label 6666 for the flow from router 6 to router 1.
+
+    $ kubectl --namespace tfs exec -ti $(kubectl --namespace tfs get pods --selector=app=teservice -o name) -c server -- /tfte/bin/tfte remote_console
+    1> {ok, Flow1to6} = epce_server:initiate_flow(<<"foo">>, {1, 1, 1, 1}, {6, 6, 6, 6}, 1111).
+    2> {ok, Flow6to1} = epce_server:initiate_flow(<<"bar">>, {6, 6, 6, 6}, {1, 1, 1, 1}, 6666).
+
+Another option is to use the router names:
+
+    1> {ok, Flow1to6} = epce_server:initiate_flow(<<"foo">>, <<"RT1">>, <<"RT6">>, 1111).
+    2> {ok, Flow6to1} = epce_server:initiate_flow(<<"bar">>, <<"RT6">>, <<"RT1">>, 6666).
+
+Now if we go to the tmux session src (Ctrl-B 0) we can ping dst:
+
+    $ ping 9.9.9.2
+
+From the Erlang console we can update the initiated flows to change the path the packets are flowing through:
+
+    3> epce_server:update_flow(Flow6to1, [16050, 16030, 16010]).
+
+### Setup a flow using the GRPC test script
+
+This does the same as the the setup from the Erlang console, but through GRPC.
+After deploying Teraflow (with te), get the te service ip using:
+
+    $ kubectl -n tfs get services
+
+Replace the IP in the python script `src/te/tests/test_te_service.py`.
+Be sure the topology as been loaded, and netgen started as described previously,
+and run the following command from the root of the teraflow controller:
+
+    $ PYTHONPATH=./src python src/te/tests/test_te_service.py
