+
+# Cite As You Write (CAYW)
+
+JabRef allows you to open up a search dialog to search for entries and their citation keys directly from your LaTeX
+editor and automatically insert them at your current cursor position.
+It works with different editors, such as TeXstudio, TeXworks, and Emacs.
+
+Make sure you set the path to the application you want to use in JabRefs settings.
+
+To use the Cite As You Write (CAYW) feature, you need to have JabRef running and the HTTP server enabled.
+
+You can enable the HTTP server in **File → Preferences → General** and under the **HTTP Server** section check the box
+for **Enable HTTP Server**.
+
+## Application setup
+
+For instructions on how to setup your editor to use the CAYW endpoint, please consult the documentation of [Better BibTeX for Zotero](https://retorque.re/zotero-better-bibtex/citing/cayw/index.html).
+
+## Endpoint parameters
+
+We are working on becoming fully compatible with the CAYW endpoint
+of [Better BibTeX for Zotero](https://retorque.re/zotero-better-bibtex/citing/cayw/index.html).
+The endpoint is available under `http://localhost:23119/better-bibtex/cayw`.

+|---------------|-----------------------------------------------------------------------------------------------|------------|
