  **Package** `dynaml.tensorflow`
 
- - The `dtf` package object houses utility functions related to tensorflow primitives. Currently supports creation of tensors from arrays.
- - The `dtflearn` package object deals with basic neural network building blocks which are often needed while constructing prediction architectures.

 ### Library Organisation
 
  - Added `dynaml-repl` and `dynaml-notebook` modules to repository.
 
 ### DynaML Server
 
- - DynaML ssh server now available 
+ - DynaML ssh server now available (only in Local mode)
    ```bash
    $ ./target/universal/stage/bin/dynaml --server
    ```
-   To login to the server open a separate shell and type
