-### Air-Gapped and Offline Environments
-
-This module supports air-gapped environments through automatic fallback mechanisms:
-
-#### Option 1: Self-hosted JetBrains API Mirror
-
-For organizations with internal JetBrains API mirrors:
-
-```tf
-module "jetbrains" {
-  count    = data.coder_workspace.me.start_count
-  source   = "registry.coder.com/coder/jetbrains/coder"
-  version  = "1.0.0"
-  agent_id = coder_agent.example.id
-  folder   = "/home/coder/project"
-
-  default = ["GO", "IU"]
-
-  # Custom API endpoints
-  releases_base_link = "https://jetbrains-api.internal.company.com"
-  download_base_link = "https://jetbrains-downloads.internal.company.com"
-}
-```
-
-#### Option 2: Fully Air-Gapped (No Internet Access)
-
-The module automatically falls back to static build numbers from `ide_config` when the JetBrains API is unreachable:
-
-```tf
-module "jetbrains" {
-  count    = data.coder_workspace.me.start_count
-  source   = "registry.coder.com/coder/jetbrains/coder"
-  version  = "1.0.0"
-  agent_id = coder_agent.example.id
-  folder   = "/home/coder/project"
-
-  default = ["GO", "IU"]
-
-  # Update these build numbers as needed for your environment
-  ide_config = {
-    "GO" = {
-      name  = "GoLand"
-      icon  = "/icon/goland.svg"
-      build = "251.26927.50" # Static build number used when API is unavailable
-    }
-    "IU" = {
-      name  = "IntelliJ IDEA"
-      icon  = "/icon/intellij.svg"
-      build = "251.26927.53" # Static build number used when API is unavailable
-    }
   }
 }
 ```
 
-**How it works:**
-
-- The module first attempts to fetch the latest build numbers from the JetBrains API
-- If the API is unreachable (network timeout, DNS failure, etc.), it automatically falls back to the build numbers specified in `ide_config`
-- This ensures the module works in both connected and air-gapped environments without configuration changes
-
 ### Single IDE for Specific Use Case

+module "jetbrains_pycharm" {
   count    = data.coder_workspace.me.start_count

   agent_id = coder_agent.example.id

+  folder   = "/workspace/project"
 
-  default = ["GO"] # Only GoLand
+  default = ["PY"] # Only PyCharm
 
   # Specific version for consistency
