-Starting with v0.9.0, `kubectx` and `kubens` **are now rewritten in Go**.  They
-should work the same way (and we'll keep the bash-based implementations around)
-but the new features will be added to the new Go programs.  Please help us test
-this new Go implementation by downloading the binaries from the [**Releases page
-→**](https://github.com/ahmetb/kubectx/releases)
+Alternatively, download binaries from the [**Releases page →**](https://github.com/ahmetb/kubectx/releases) and add them to somewhere in your `PATH`.

-### Kubectl Plugins (macOS and Linux)
-
-You can install and use the [Krew](https://github.com/kubernetes-sigs/krew/) kubectl
-plugin manager to get `kubectx` and `kubens`.

-```
-
-After installing, the tools will be available as `kubectl ctx` and `kubectl ns`.
-
-### Homebrew (macOS and Linux)
-
-If you use [Homebrew](https://brew.sh/) you can install like this:

-
-This command will set up bash/zsh/fish completion scripts automatically. Make sure you [configure your shell](https://docs.brew.sh/Shell-Completion) to load completions for installed Homebrew formulas.

-
-### Manual Installation (macOS and Linux)
-
-Since `kubectx` and `kubens` are written in Bash, you should be able to install
-them to any POSIX environment that has Bash installed.
-
-- Download the `kubectx`, and `kubens` scripts.
-- Either:
-  - save them all to somewhere in your `PATH`,
-  - or save them to a directory, then create symlinks to `kubectx`/`kubens` from
-    somewhere in your `PATH`, like `/usr/local/bin`
-- Make `kubectx` and `kubens` executable (`chmod +x ...`)
-
-Example installation steps:
-
-``` bash
-sudo git clone https://github.com/ahmetb/kubectx /opt/kubectx
-sudo ln -s /opt/kubectx/kubectx /usr/local/bin/kubectx
-sudo ln -s /opt/kubectx/kubens /usr/local/bin/kubens
-```
