 An Environment Definition File (EDF) is a text file in the [TOML format](https://toml.io/en/) that declaratively and prescriptively represents the creation of a computing environment based on a container image.
 Users can create their own custom environments and share, edit, or build upon already existing environments.
 
-The Container Engine (CE) toolset leverages its tight integration with the Slurm workload manager to parse EDFs directly from the command line or batch script and instantiate containerized user environments seamlessly and transparently.

 ### Using NCCL from remote SSH terminals
 
-We are aware of an issue when enabling both [the AWS OFI NCCL hook][ref-ce-aws-ofi-hook] and [the SSH hook][ref-ce-ssh-hook], and launching programs using NCCL from Bash sessions connected via SSH.
+We are aware of an issue when enabling both [the AWS OFI NCCL hook][software/container-engine/resource-hook.md#ref-ce-aws-ofi-hook] and [the SSH hook][software/container-engine/resource-hook.md#ref-ce-ssh-hook], and launching programs using NCCL from Bash sessions connected via SSH.
 The issue manifests with messages reporting `Error: network 'AWS Libfabric' not found`.
 
 In addition to setting up a server for remote connections, the SSH hook also performs actions intended to improve the user experience. One of these is creating a script to be loaded by Bash in order to propagate the container job environment variables when connecting through SSH.
