 ??? tip "Exporting your environment"
     If you are working with Conda users or systems, you can [export your environment to a `environment.yml`](../reference/cli.md#project-export-conda_environment) file to share them.
     ```shell
-    pixi project export conda
+    pixi project export conda-environment
     ```
     Additionally you can export a [conda explicit specification](../reference/cli.md#project-export-conda_explicit_spec).
