 # starknet-replay
 Provides a way of reading a real Starknet State, so you can re-execute an existing transaction in any of the Starknet networks in an easy way
 
+## Getting Started
+
+### Prerequisites
+
+- Linux or macOS (aarch64 included) only for now
+- LLVM 18 with MLIR
+- Rust 1.78.0 or later, since cairo-native makes use of the u128 abi change.
+- Git
+
+### Setup
+
+Run the following make target to install dependencies:
+```bash
+make deps
+```
+It will automatically install LLVM 18 with MLIR on macos, if you are using linux you must do it manually. On debian, you can use `apt.llvm.org`, or build it from source.
+
+This project is integrated with Cairo Native, see [Cairo Native Setup](#cairo-native-setup) to set it up correctly
+
+Some environment variable are needed, you can automatically set them by sourcing `env.sh`. If the script doesn't adjust to your specific environment you can `cp` it into `.env` or `.envrc` and modify it.
+```bash
+# Cairo Native
+export LLVM_SYS_181_PREFIX=/path/to/llvm-18
+export MLIR_SYS_180_PREFIX=/path/to/llvm-18
+export TABLEGEN_180_PREFIX=/path/to/llvm-18
+export CAIRO_NATIVE_RUNTIME_LIBRARY=/path/to/cairo_native/target/release/libcairo_native_runtime.a
+# RPC
+export RPC_ENDPOINT_MAINNET=rpc.endpoint.mainnet.com
+export RPC_ENDPOINT_TESTNET=rpc.endpoint.testnet.com
+```
+
+Once you have installed dependencies and set the needed environment variables, you can build the project and run the tests:
+```bash
+make build
+make test
+```
+
 ### Cairo Native Setup
 
 Starknet Replay is currenlty integrated with [Cairo Native](https://github.com/lambdaclass/cairo_native), which makes the execution of sierra programs possible through native machine code. To use it, the following needs to be setup:
 
-- LLVM `18` needs to be installed and the `MLIR_SYS_180_PREFIX` and `TABLEGEN_180_PREFIX` environment variable needs to point to said installation. In macOS, run
+- On mac with brew, running `make deps` should have installed LLVM 18 with MLIR, otherwise, you must install it manually. On Debian, you can use `apt.llvm.org`, or build it from source.
+
+- The `LLVM_SYS_181_PREFIX`, `MLIR_SYS_180_PREFIX` and `TABLEGEN_180_PREFIX` environment variable needs to point to said installation. In macOS, run:
   ```
-  brew install llvm@18
-  export MLIR_SYS_180_PREFIX=/opt/homebrew/opt/llvm@18
   export LLVM_SYS_180_PREFIX=/opt/homebrew/opt/llvm@18
+  export MLIR_SYS_181_PREFIX=/opt/homebrew/opt/llvm@18
   export TABLEGEN_180_PREFIX=/opt/homebrew/opt/llvm@18
   ```
   and you're set.
