+Module for managing Federated Learning Workspaces.
+This module provides a set of commands and functions to create, import, export, and manage
+Federated Learning workspaces. It includes functionalities for setting up workspace directories,
+creating workspace templates, generating certificates, and packaging workspaces as Docker images.
+
+Commands:
+    create: Create the workspace.
+    import: Import a federated learning workspace generated by `fx workspace export`.
+    certify: Create certificate authority for federation.
+    export: Export the OpenFL workspace (in current directory) to an archive.
+    dockerize: Package the current workspace as a Trusted Execution Environment (TEE)-ready Docker image.

+    Package the current workspace as a Trusted Execution Environment (TEE)-ready Docker image.
+
+    This command exports the current workspace, builds an OpenFL base Docker image,
+    constructs the workspace Docker image, and optionally saves the workspace image as a tarball file.    
+    Steps Performed:
+        1. Exports the current workspace as an archive.
+        2. Builds the OpenFL base Docker image using the specified or default revision.
+        3. Builds the workspace Docker image, incorporating the exported workspace and signing key.
+        4. Optionally saves the workspace Docker image as a `.tar` file.
 
+    Raises:
+        FileNotFoundError: If the provided enclave key path does not exist.
+        RuntimeError: If any Docker commands fail during the build or export process.
+
+    Notes:
+        - If no enclave key is provided, a new one is generated using OpenSSL and saved in the workspace.
+        - The generated image is compatible with TEE environments but can be used outside of TEE if needed.
+        - Docker BuildKit is utilized for efficient and secure image builds.
