Installing Deno
Get Deno Release Binary
Deno is still at very early development stage. The current releases are 0.2.x, which are defined to be "mildly usable" and is mostly for developer preview.
To install Deno release binary, run the following commands on *nix
curl -L https://deno.land/x/install/install.py | python
export PATH=$HOME/.deno/bin:$PATH
On windows, you might want to install through Powershell:
iex (iwr https://deno.land/x/install/install.ps1)
Deno is installed through scripts from deno_install. If you encountered any installation problems, submit an issue there.

If you are interested in contributing to Deno, you might want to compile Deno from source yourself.
Run the following commands to get make a debug build
# Fetch deps.
git clone --recurse-submodules https://github.com/denoland/deno.git
cd deno
# Setup and download important third party tools
./tools/setup.py
