 # Computation Supported
 
-- Tensornet (TN)
-    - TN contraction to dense vector
-    - TN contraction to dense vector with Message Passing Interface (MPI)
-    - TN contraction to dense vector with NCCL
-    - TN contraction to expectation of given Pauli string
-    - TN contraction to expectation of given Pauli string with Message Passing Interface (MPI)
-    - TN contraction to expectation of given Pauli string with NCCL
+1. Tensornet (TN) with contractions to:
+    - dense vector
+    - expecation of given Pauli string
 
-- Matrix Product State (MPS)
-    - MPS contraction to dense vector
+    For each TN case:
+    - single node
+    - multi node with Message Passing Interface (MPI)
+    - multi node with NCCL
+
+2. Tensornet (TN) with contractions to:
+    - dense vector (single node)

 ## Multi-Node
 Multi-node is enabled by setting either the MPI or NCCL enabled flag to True in the computation settings. Below shows the script to launch on 2 nodes with 2 GPUs each. $node_list contains the IP of the nodes assigned.
