+`{icon}` identifiers. For example, you can use the JsDelivr CDN:
+
+Using [JsDelivr](https://cdn.jsdelivr.net/npm/iconista@2/sets/lucide/beef.svg):
+
+```
+https://cdn.jsdelivr.net/npm/iconista@2/sets/{set}/{icon}.svg
+```
+
+Using [UNPKG](https://unpkg.com/iconista@2/sets/lucide/beef.svg):
+
+```
+https://unpkg.com/iconista@2/sets/{set}/{icon}.svg
+```
+
+Using [ESM.sh](https://esm.sh/iconista@2.18.0/sets/lucide/beef.svg):
+
+```
+https://esm.sh/iconista@2/sets/{set}/{icon}.svg
+```
