 # Cairo Bootcamp 5.0
 This repository contains all the codes for Cairo Bootcamp 5.0
+
+## Set up instructions
+To set up this repository, you will need to install [Starkup](https://github.com/software-mansion/starkup). 
+
+StarkUp installs and setup the following packages in your machine: 
+- Scarb -  the Cairo package manager
+- Starknet Foundry - the Cairo and Starknet testing framework
+- Universal Sierra Compiler  - compiler for any ever-existing Sierra version
+- Cairo Profiler - profiler for Cairo programming language & Starknet
+- Cairo Coverage - utility for coverage reports generation for code written in Cairo programming language
+- CairoLS - vscode extension
+
+
+Run the following command to install StarkUp: 
+```bash
+curl --proto '=https' --tlsv1.2 -sSf https://sh.starkup.sh | sh
+```
+
+## Build and Test Contracts
+To build and test the contracts, run the following commands
+
+**Build contracts**
+```bash
+scarb build
+```
+
+**Run contract tests**
+```bash
+scarb run test
+```
+
+> `scarb run test` runs `snforge test` under the hood. So you can optionally use `snforge test` to test the contracts
