31## Ark Installation
32
33To use the Zed REPL with R you need to install [Ark](https://github.com/posit-dev/ark), an R Kernel for Jupyter applications.
34You can down the latest version from the [Ark GitHub Releases](https://github.com/posit-dev/ark/releases) and then extract the `ark` binary to a directory in your `PATH`.
35
36For example to install the latest non-debug build:
37
38```sh
39# macOS
40cd /tmp
41curl -L -o ark-latest-darwin.zip \
42    $(curl -s "https://api.github.com/repos/posit-dev/ark/releases/latest" | \
43    jq -r '.assets[] | select(.name | contains("darwin-universal") and (contains("debug") | not)) | .browser_download_url')
44unzip ark-latest-darwin.zip ark
45sudo mv /tmp/ark /usr/local/bin/
46```
47
48```sh
49# Linux X86_64
50cd /tmp
51curl -L -o ark-latest-linux.zip \
52    $(curl -s "https://api.github.com/repos/posit-dev/ark/releases/latest" \
53        | jq -r '.assets[] | select(.name | contains("linux-x64") and (contains("debug") | not)) | .browser_download_url'
54    )
55unzip ark-latest-linux.zip ark
