+## Build Instructions
+
+This project relies on `conan` (v2) for dependency management (Eigen3, Boost) and `cmake` for configuration. VTK is provided through the micromamba/conda-forge environment.
+
+### Prerequisites
+
+This project requires a `conda` or `micromamba` environment containing the necessary global tools like **ROOT**, **VTK**, and **Conan** (v2). We provide a `condaenv.yml` file to quickly build this environment.
+
+#### Installing Micromamba (Optional)
+
+If you do not have `conda` installed, `micromamba` is a fast and lightweight alternative. You can install it on Linux via:
+
+```bash
+"${SHELL}" <(curl -L micro.mamba.pm/install.sh)
+```
+
+#### Creating the Environment
+
+You can create and activate the environment using either `micromamba` or `conda`.
+
+**Using Micromamba:**
+```bash
+micromamba env create -f condaenv.yml
+micromamba activate mutom
+```
+
+**Using Conda:**
+```bash
+conda env create -f condaenv.yml
+conda activate mutom
+```
+
+### Configure and Build
+
+1. **Configure Conan profile (if you haven't yet on your machine):**
+```bash
+conan profile detect
+```
+
+2. **Install Conan dependencies:**
+```bash
+conan install . --output-folder=build --build=missing
+```
+
+3. **Configure the project with CMake:**
+```bash
+cmake --preset conan-release
+```
+*(Alternatively: `cd build && cmake .. -DCMAKE_TOOLCHAIN_FILE=conan_toolchain.cmake -DCMAKE_BUILD_TYPE=Release`)*
+
+4. **Build the project:**
+```bash
+cmake --build build -j10
+```
