 # Installation
 
 ## 1.1. Installation under OS GNU/Linux.
-### 1. Download the source code of Free Oberon as an archive from the site <freeoberon.su>. The archive with the version for Windows OS is also suitable, because it also contains the source codes. Unzip the archive to your home directory or to another location on the disk.
-### 2. Using the terminal or in any other way, install the following software packages on your system:
-* libsdl2-dev
-* libsdl2-image-dev
-* binutils
-* gcc
-* make
-* git (optionally)
-The names of the packages are given in accordance with their name in the Debian GNU/Linux operating system. They are suitable for users of Ubuntu, Linux Mint, Raspbian and some other distributions.
-To install them, run the following command:
-```
-apt-get install -y libsdl2-dev libsdl2-image-dev binutils gcc make git
-```
-(This command must be executed with superuser privileges, that is, you must first run su and enter the password.)
-On OS Fedora, Red Hat, CentOS and others, the command and package names will differ:
-```
-sudo yum install SDL2-devel SDL2_image-devel binutils gcc make git    (not tested!)
-```
-### 3. Using the terminal, enter the following directory:
-```
-cd FreeOberon/data/bin/voc
-```
-Here is a modified version of the VOC compiler.
-### 4. Run the Vishap Oberon Compiler compilation:
-```
-make full
-```
-### 5. If the compilation was successful, get the superuser's rights (by the command `su` or by assigning `sudo`), and then run:
-M ake install
-The VOC compiler files will be installed in `/opt/voc`.
-### 6. Open the file `~/.bashrc` and add the following line to the end:
-```
-export PATH="/opt/voc/bin:$PATH"
-```
-This is necessary so that you can run "voc" from the command line (and that Free Oberon can do it).
-### 7. In the terminal, go to the `FreeOberon/src` directory:
-```
-cd FreeOberon/src
-```
-### 8. Compile Free Oberon:
-```
-make -f Makefile_linux
-```
-### 9. (optional) Add the line `~/.bashrc` to the end of the file:
-```
-alias fo='cd ~/FreeOberon;./ FreeOberon'
-```
-So that Free Oberon can be run with the `fo` command.
