 On August 10, 2023, HashiCorp announced a change of license for its products, including Terraform. After ~9 years of Terraform being open source under the MPL v2 license, it was to move under a non-open source BSL v1.1 license, starting from the next (1.6) version. See https://github.com/hashicorp/terraform/blob/main/LICENSE
 
+## Custom Download Server
+
+The `customDownloadServer` option allows you to specify an alternative server for downloading Terraform and Sentinel packages. This is useful for organizations that maintain internal mirrors or have proxies for HashiCorp downloads.
+
+When using this option:
+- Provide the complete URL including protocol (e.g., `https://my-mirror.example.com`)
+- The server should mirror the HashiCorp releases structure
+
+Example:
+```json
+"features": {
+    "ghcr.io/devcontainers/features/terraform:1": {
+        "customDownloadServer": "https://my-mirror.example.com"
+    }
+}
+```
+
+### ⚠️ Security Considerations
+
+When using a custom download server, be aware of the following security implications:
+
+- **Server Verification**: Always verify that the custom server is trustworthy and maintained by your organization or a trusted entity. Using an untrusted or compromised server could lead to downloading malicious software.
+  
+- **Supply Chain Risks**: Malicious actors may attempt to distribute compromised versions of Terraform that contain backdoors, cryptominers, or other harmful code.
+  
+- **Integrity Checks**: The feature performs SHA256 checks when available, but these are only as trustworthy as the source of the checksums. If both the binaries and checksums come from a compromised server, the integrity check may pass despite the software being malicious.
+  
+- **Organizational Policy**: Ensure your custom download server adheres to your organization's security policies and implements proper access controls.
+
+Always use the official HashiCorp download server (https://releases.hashicorp.com) unless you have a specific need for an alternative source.
+
 ## OS Support
 
 This Feature should work on recent versions of Debian/Ubuntu-based distributions with the `apt` package manager installed.
