 ## Dependencies
 
+### Build tools
+
+- CMake 3.16+
+- Clang or GCC (tested with GCC 13)
+- Ninja (recommended)
+
+### Libraries
+
+- [evmc](https://github.com/ethereum/evmc)
+- [intx](https://github.com/chfast/intx)
 - [blueprint](https://github.com/NilFoundation/zkllvm-blueprint)
 - [crypto3](https://github.com/NilFoundation/crypto3)
 
+## Nix support
+
+`evm-assigner` supports [Nix](https://nixos.org/) flakes. This means that you can get development-ready environment with:
+
+```bash
+nix develop
+```
+
+Build package:
+
+```bash
+nix build
+```
+
+Run tests:
+
+```bash
+nix flake check
+```
+
 ## Build
 
 ### Configure cmake
 
-```
+```bash
 cmake -G "Ninja" -B build -DCMAKE_BUILD_TYPE=Release -DBUILD_ASSIGNER_TESTS=TRUE
 
 ```
 
 ### Build test
 
-```
+```bash
 cmake --build build -t assigner_tests
 ```
