-$ source $HOME/.cargo/env
-$ rustup component add rustfmt
+curl https://sh.rustup.rs -sSf | sh

 ```
 
 When building the master branch, please make sure you are using the latest stable rust version by running:
 
 ```bash
-$ rustup update
+rustup update
 ```
 
 When building a specific release branch, you should check the rust version in `ci/rust-version.sh` and if necessary, install that version by running:
 ```bash
-$ rustup install VERSION
+rustup install VERSION
 ```
 Note that if this is not the latest rust version on your machine, cargo commands may require an [override](https://rust-lang.github.io/rustup/overrides.html) in order to use the correct version.
 
 On Linux systems you may need to install libssl-dev, pkg-config, zlib1g-dev, protobuf etc.
 
 On Ubuntu:
 ```bash
-$ sudo apt-get update
-$ sudo apt-get install libssl-dev libudev-dev pkg-config zlib1g-dev llvm clang cmake make libprotobuf-dev protobuf-compiler
+sudo apt-get update

 ```bash
-$ sudo dnf install openssl-devel systemd-devel pkg-config zlib-devel llvm clang cmake make protobuf-devel protobuf-compiler perl-core

-$ cd tachyon
+git clone https://github.com/x1-labs/tachyon.git

 ### **3. Build.**
 
 ```bash
-$ ./cargo build
+# To build with debug profile for development only
+cargo build
+
+# To build with release profile for production
+cargo build --release
 ```
 
 ## Testing
 
 **Run the test suite:**
 
 ```bash
-$ ./cargo test
+cargo test
 ```

 ## Benchmarking
 
 First, install the nightly build of rustc. `cargo bench` requires the use of the
 unstable features only available in the nightly build.
 
 ```bash
-$ rustup install nightly
+rustup install nightly
 ```
 
 Run the benchmarks:
 
 ```bash
-$ cargo +nightly bench
+cargo +nightly bench
