+# openlinksinnewpage Extension For Quarto
+
+With the `openlinksinnewpage` filter [hyperlinks](https://quarto.org/) automatically open in a new page, similarly to adding `{target="_blank"}` to your markdown hyperlinks.
+
+Packaged up as an extension following suggestion by @cscheid on a discussion [here](https://github.com/quarto-dev/quarto-cli/discussions/3169){target="_blank"}.
+
+This provides an alternative to using the following syntax
+
+```md
+[quarto](https://quarto.org/){target="_blank"}
+```
+
+if you want all links to be opened in a new page.
+
+## Installing
+
+```bash
+quarto add davidwilby/openlinksinnewpage
+```
+
+This will install the extension under the `_extensions` subdirectory.
+If you're using version control, you will want to check in this directory.
+
+## Using
+
+Carry on as usual! Ensure that the following is in your yaml frontmatter:
+
+```yaml
+filters:
+    - openlinksinnewpage
+```
+
+All the links in your quarto document or presentation will open in a new page or tab.
+
+## Example
+
+Here is the source code for a minimal example: [example.qmd](example.qmd).
