+==Checking your environment==
+
+EiffelStudio requires GTK+ 2.4.0 or above to function properly. You can check that you have this installed correctly by typing the following command:
+pkg-config --modversion gtk+-2.0
+The command should succeed and the version number of GTK+ should appear. If it is not 2.4.0 or above then you cannot continue the installation of EiffelStudio. You first need to install GTK+ 2.4.0.
+
+==Installing EiffelStudio from the Web==
+
+After downloading the installation package, you should manually extract its contents to your hard drive. For example, you can extract it into /usr/local using the following commands (assuming that you have permission to /usr/local and that the installation package was saved in /tmp/EiffelXX.tar.bz2, where XX corresponds to the EiffelStudio version number):
+
+cd /usr/local
+tar xvfj /tmp/EiffelXX.tar.bz2
+
+This will install EiffelStudio files into /usr/local/EiffelXX. Once this is done, jump to the [[#Setting up EiffelStudio|Setting up EiffelStudio]] section in order to complete the installation of EiffelStudio.
+
+==Installing EiffelStudio from a CD-ROM==
+
+Insert the CD into your CD-ROM drive. You should manually extract its contents to your hard drive. For example you can extract it in /usr/local using the following commands (assuming that you have permission to /usr/local and that the CD is mounted on /mnt/cdrom):
+cd /usr/local
+cp -r /mnt/cdrom/EiffelXX .
+
+This will install the EiffelStudio files into /usr/local/EiffelXX. To complete the installation of EiffelStudio, jump to the next section, [[#Setting up EiffelStudio|Setting up EiffelStudio]].
+
+==Setting up EiffelStudio==
+
+Once the files have been installed, you should define the following environment variables in order to run EiffelStudio:
+* '''ISE_EIFFEL''' to /usr/local/EiffelXX
+* '''ISE_PLATFORM''' to freebsd-x86.
+and add $'''ISE_EIFFEL'''/studio/spec/$'''ISE_PLATFORM'''/bin to your '''PATH''' environment variable.
+
+Using sh or bash as a shell, it suffices to type the following commands:
+
+export ISE_EIFFEL=/usr/local/EiffelXX
+export ISE_PLATFORM=freebsd-x86
+export PATH=$PATH:$ISE_EIFFEL/studio/spec/$ISE_PLATFORM/bin
+
+
+Using csh or tcsh as a shell, it suffices to type the following commands:
+
+setenv ISE_EIFFEL /usr/local/EiffelXX
+setenv ISE_PLATFORM freebsd-x86
+set path = ($path $ISE_EIFFEL/studio/spec/$ISE_PLATFORM/bin)
+
+
+If you are using the Enterprise edition, please follow the instructions of the next section, [[#Registering the Enterprise Edition|Registering the Enterprise Edition]], otherwise jump to the [[#Using EiffelStudio|Using EiffelStudio]] section at the end of this document.
+
+==Registering the Enterprise Edition==
+
+This step assumes you have followed the instructions in the [[#Setting up EiffelStudio|Setting up EiffelStudio]] section. Perform the following commands to start the registration process:
+cd $ISE_EIFFEL
+./register
+
+A dialog asking for your '''Username''' and '''CD Key''' should appear as it does below:
