 - Ruby 2.x. The gRPC API uses keyword args.
-- [homebrew][] on Mac OS X.  These simplify the installation of the gRPC C core.
 
 INSTALLATION
 ---------------
 
-**Linux (Debian):**
-
-Add [Debian jessie-backports][] to your `sources.list` file. Example:
-
-```sh
-echo "deb http://http.debian.net/debian jessie-backports main" | \
-sudo tee -a /etc/apt/sources.list
-```
-
-Install the gRPC Debian package
-
-```sh
-sudo apt-get update
-sudo apt-get install libgrpc-dev
-```
-
-Install the gRPC Ruby package
+**Linux and Mac OS X:**
 
 ```sh
 gem install grpc
 ```
 
-**Mac OS X**
-
-Install [homebrew][]. Run the following command to install gRPC Ruby.
-```sh
-$ curl -fsSL https://goo.gl/getgrpc | bash -s ruby
-```
-This will download and run the [gRPC install script][], then install the latest version of gRPC Ruby gem.  It also installs Protocol Buffers compiler (_protoc_) and the gRPC _protoc_ plugin for ruby.
-
 BUILD FROM SOURCE
 ---------------------
 - Clone this repository
