Luria Voice depends on a small set of external tools and R packages. The table below lists every dependency, its minimum version, whether it is required or optional, and where to get it. Detailed install instructions follow.

​
Quarto

Quarto ≥ 1.4.0 is required. Quarto 1.4 introduced the Typst output format that Luria Voice depends on. Download the installer for your operating system from quarto.org. After installing, confirm your version: 
quarto --version
The output should be 1.4.0 or higher.
Quarto ≥ 1.4.0 ships with Typst embedded. You do not need to install Typst separately. If you have a standalone Typst installation, Quarto uses its own bundled copy and the two will not conflict.

​
R

R 4.2 or later is recommended. Download from cran.r-project.org. Confirm your version in R: 
R.version$major
R.version$minor

​
R packages

Install all required CRAN packages in a single command: 
install.packages(c(
  "dplyr",
  "readr",
  "here",
  "yaml",
  "ggplot2",
  "systemfonts"
))

​
cingulate (GitHub)

The cingulate package provides the scoring, norming, and domain-assembly pipeline that populates report sections. It is not on CRAN and must be installed from GitHub.
1

Install the remotes package

If you do not already have remotes, install it from CRAN:
install.packages("remotes")
2

Install cingulate from GitHub

remotes::install_github("brainworkup/cingulate")
3

Verify the installation

library(cingulate)
If this command runs without error, cingulate is installed correctly.
remotes::install_github requires an internet connection and access to GitHub. If you are behind a corporate firewall, contact your IT department to allow outbound connections to api.github.com and codeload.github.com.

​
Ollama (optional)

Ollama enables AI-generated narrative summaries within the report. It is entirely optional — all scoring, tables, and figures render without it. If you want to use AI narratives:
1

Download and install Ollama

Download Ollama from ollama.com and follow the installer for your platform.
2

Pull a model

ollama pull llama3
3

Start the Ollama server before rendering

ollama serve
Ollama must be running on localhost:11434 when you call quarto render. If it is not running, the narrative generation step will time out and log an error.

​
Installing everything at once

The following block installs all R dependencies in a single session. Run it once after a fresh R installation. 
install.packages(c(
  "dplyr",
  "readr",
  "here",
  "yaml",
  "ggplot2",
  "systemfonts",
  "remotes"
))

remotes::install_github("brainworkup/cingulate")
