+
+## Variables Quarto inspects
+
+These are variables that you can set to control how Quarto renders documents. For example, you can set them explicitly before running `quarto render`:
+
+``` {.bash filename="Terminal"}
+export QUARTO_R=/opt/R/4.2.3/bin
+quarto render
+```
+
+You can read about other ways to set environment variables in Quarto Projects in [Environment Variables](/docs/projects/environment.qmd).
+
+| Variable        | Description |
+|-----------------|-------------|
+| `QUARTO_R`      |             |
+| `QUARTO_PYTHON` |             |
+|                 |             |
+
+## Variables Quarto sets
+
+These variables are set by Quarto you can query them. For example, you can query them in an executable code cell:
+
+::: panel-tabset
+## R
+
+``` r
+Sys.getenv("QUARTO_DOCUMENT_PATH")
+```
+
+## Python
+
+``` python
+import os
+print(os.environ["QUARTO_DOCUMENT_PATH"])
+```
+
+## Julia
+
+``` julia
+ENV["QUARTO_DOCUMENT_PATH"]
+```
+:::
+
+| Variable | Description |
+|----------------|--------------------------------------------------------|
+| `QUARTO_PROJECT_ROOT` | Root of the project, or the directory of the file if not in project mode |
+| `QUARTO_DOCUMENT_PATH` | Directory of the document being rendered |
+| `QUARTO_PROFILE` | Profile used, e.g `QUARTO_PROFILE=advanced,production` for `quarto render --profile advanced,production` |
