+# Export to PDF
+
+This #recipe shows how to export a note to PDF.
+
+## Required extensions
+
+- **[vscode-pandoc](https://marketplace.visualstudio.com/items?itemName=chrischinchilla.vscode-pandoc)**
+
+## Required third-party tools
+
+- [Pandoc](https://pandoc.org/installing.html)
+- A [LaTeX distribution](https://www.latex-project.org/get/) such as TeXLive (Linux), MacTeX (MacOS), or MikTeX (Windows)
+
+Check that Pandoc is installed by opening a terminal and running `pandoc --version`.
+
+Check that Pandoc can produce PDFs with LaTeX by running the following in the terminal.
+
+```
+echo It is working > test.md
+pandoc test.md -o test.pdf
+```
+
+## Instructions
+
+1. Create a folder in your workspace named `.pandoc`. Take note of the full path to this directory. The rest of this recipe will refer to this path as `$WORKSPACE/.pandoc`.
+
+2. Download the template file [`foam.latex`](https://raw.githubusercontent.com/Hegghammer/foam-templates/main/foam.latex) from [Hegghammer/foam-templates](https://github.com/Hegghammer/foam-templates) and place it in `$WORKSPACE/.pandoc`.
+
+3. In VSCode, open `settings.json` for your user (or just for your workspace if you prefer), and add the following line:
+
+```
+"pandoc.pdfOptString": "--from=markdown+wikilinks_title_after_pipe --resource-path $WORKSPACE/.pandoc --template foam --listings",
+```
+
+Make sure to replace `$WORKSPACE/.pandoc` with the real full path to the `.pandoc` directory you created earlier.
+
+4. Open a Foam note in VSCode.
+
+5. Press `Ctrl` + `k`, `p`. Choose "pdf", and press `Enter`.
+
+The PDF should look something like this:
+
+![Sample PDF output](../../assets/images/pdf_output.png)
+
+## Options
+
+If you include a name in the `author` parameter in the YAML of the Foam note, that name will feature in the PDF header on the top left.
+
+If you don't want syntax highlighting and frames around the codeblocks, remove `--listings` from the `pandoc.pdfOptString` parameter in `settings.json`.
+
+## Further customization
+
+If you know some LaTeX, you can [tweak](https://bookdown.org/yihui/rmarkdown-cookbook/latex-template.html) the `foam.latex` template to your needs. Alternatively, you can supply another ready-made template such as [Eisvogel](https://github.com/Wandmalfarbe/pandoc-latex-template); just place the `TEMPLATE_NAME.latex` file in `$WORKSPACE/.pandoc`. You can also use all of Pandoc's [other functionalities](https://learnbyexample.github.io/customizing-pandoc/) by tweaking the `pandoc.pdfOptString` parameter in `settings.json`.
