+= Configuring editors download URLs
+
+This procedure describes how to configure download URLs for editors. This feature is valuable in air-gapped environments where editors cannot be retrieved from the public internet. Currently, this option is intended only for JetBrains editors and should not be used for other editor types.
+
+.Prerequisites
+
+* You have an active `_orch-cli_` session with administrative permissions to the `{orch-name}` cluster. For more information, see {orch-cli-link}.
+
+* `jq`. See link:https://stedolan.github.io/jq/download/[Downloading `jq`].

+.Procedure

+      "devEnvironments": {
