Your world is about to change. Welcome to Red.

To install Red locally...

Download the correct Red binary version for your computer from here (takes only a few seconds, it's less than 1MB). Save into a suitable folder.

For Windows users: Run it by double-clicking on the Red binary file.
It will then automatically build the Red GUI-console.
Next time you double-click on the file, the GUI-console will automatically open.

For Linux/OSX users: You need to open a terminal app to be able to run Red.
Once you have opened the terminal app, change to the directory in which you saved Red.
Now do a: chmod u+x which will make sure that Red can be run on your computer.
After that, run Red using ./. This will build the Red console.
Next time you run Red, the console will automatically open.

(*) For Linux 64-bit distros, you need to install 32-bit supporting libraries. So, for Debian-based distros, install them using:

sudo apt-get install ia32-libs libc6-i386 libcurl3

If you are using a Debian 7+ or Ubuntu 13.10+ version, you should use the multiarch way:

dpkg --add-architecture i386
apt-get update
apt-get install libc6:i386 libcurl3:i386

For Fedora/Redhat/Centos distros:

sudo yum install glibc.i686
sudo yum install libcurl.i686

For FreeBSD, no prebuilt binaries yet, you need to cross-compile, or get the Red sources, a Rebol interpreter (here) and a couple packages: libcrypto.so.8, which can be found in the openssl package, and libcurl.so.4 (temporary dependency):

pkg install openssl
pkg install fpc-libcurl-3.0.2

For ArchLinux, there is a Red package there.
