+# Installation
+
+## Requirements
+
+* curl
+* wget
+* m4
+* GNU make
+* Intel Fortran compiler
+* Python
+* Bash
+
+
+By default, the Ocaml compiler will be installed in `$HOME/ocamlbrew`.
+To install it somewhere else, set the `$OCAMLBREW_BASE` environment
+variable to the required destination, for example:
+
+    export OCAMLBREW_BASE=/usr/local/ocamlbrew
+
+For more info about the Ocaml installation, check the ocamlbrew
+website : https://github.com/hcarty/ocamlbrew
+
+
+
+## Installing behind a firewall
+
+1) Download `tsocks`:
+
+    wget http://sourceforge.net/projects/tsocks/files/latest/download
+    mv download tsocks.tar.gz
+
+2) Tranfer `tsocks.tar.gz` on the remote host
+
+3) Configure `tsocks` with the proper directory for the `tsocks.conf` file:
+
+    tar -zxvf tsocks.tar.gz
+    cd tsocks-*
+    ./configure --with-conf=${PWD}/tsocks.conf
+
+4) Create the `tsocks.conf` file with the following content:
+
+    server = 127.0.0.1
+    server_port = 10000
+
+5) Create the tsocks library:
+
+    make
+
+6) Add the `libtsocks.so` to the `LD_PRELOAD` environment variable:
+
+    export LD_PRELOAD="${PWD}/libtsocks.so.1.8"
+
+7) Create a custom curl command to set the tsocks option: open a file named
+   `curl`, which is accessible from your `PATH` environment variable before the
+   real `curl` command, and fill this file with:
+
+    #!/bin/bash
+    /usr/bin/curl --socks5 127.0.0.1:10000 $@
+
+8) Start a tsocks ssh tunnel:
+
+    ssh -fN -D 10000 user@external-server.com
+
