+# @rramos notes
+I configured the project to run with Embark (Only demo.py was tested). To run this project in Ubuntu, the following steps need to be executed
+
+1. `npm install`
+2. Open at least 4 terminals (you can use `tmux` for this)
+3. In Terminal-1, execute `embark simulator`
+4. In Terminal-2, execute `embark run`
+5. In Terminal-3: 
+```
+cd plasma_cash
+virtualenv erc721plasma -p python3.6
+source erc721plasma/bin/activate
+pip install -r requirements.txt
+FLASK_APP=./child_chain FLASK_ENV=development flask run --port=8546
+```
+6. In Terminal-4:
+```
+cd plasma_cash
+source erc721plasma/bin/activate
+python demo.py
+```
+ 
+ Most of the previous instructions are covered here, I just wrote them here for quick reference.
+
+If installing the server from scratch:
+ 1. Install Nodejs with `nvm`
+ 2. Follow the instructions from Embark for its installation, 
+ 3. `sudo apt install virtualenv python3 python3-dev libssl-dev build-essential` 
+
+ _NOTE_: `nvm` and Embark must be installed with a normal user. Don't use `root`!

 # Development Dependencies
 
 A patched version of web3.py is used because otherwise it does not work with Ganache due to issue #674. In addition, in order to be able to monitor events, PR #827, which is not merged yet. Pyethereum dependencies broke recently so we need to manually install a slightly older version of rlp encoding. Flask is used for server purposes.
