 # Building Hyperledger Avalon With SCONE Workers
 
-- Branch 'main' represents the code of workers in SCONE Secure Hw Mode

 ## Install and Access SCONE
 
 - In order to build, install, and run Hyperledger Avalon with SCONE, SCONE must be installed and configured.

-## RUN in Hardware Mode with File System and Network Shields enabled by SCONE CAS (Secure)
-
-- To run the in Secure Hardware Mode, get the latest code from master branch:
-
-  ```bash
-  git clone https://github.com/T-Systems-MMS/hyperledger-avalon-scone.git
-  ```
-
-- To run the in Hardware Mode, you can run scone-demo.sh script from the project root directory:
-
-  ```bash
-  ./scone-demo.sh start
-  ./scone-demo.sh stop
-  ```
-  It automatically starts SCONE CAS and LAS, then it creates images for SCONE KME and SCONE Workers. You can change the number of workers in config/scone_config.toml and docker-compose-scone-avalon.yaml files. In basic demo there are 5 SCONE workers which have some pre-existing examples too.
