+# Day 1 with OpenLIFU: Getting Started Without Hardware
+
+This guide documents a first-time setup experience for OpenLIFU on Windows. The goal is to clone the repository, create a local development environment, install OpenLIFU, and explore the project without requiring physical hardware.
+
+> **Platform tested:** Windows PowerShell  
+> **Python used:** Python 3.12  
+> **Hardware required:** None
+
+## 1. Clone the Repository
+
+Clone your fork of the repository:
+
+```powershell
+git clone https://github.com/YOUR-USERNAME/openlifu-python.git
+cd openlifu-python
+```
+
+Replace `YOUR-USERNAME` with your GitHub username.
+
+Verify the repository remote:
+
+```powershell
+git remote -v
+```
+
+## 2. Check Your Python Version
+
+OpenLIFU supports Python 3.10 through Python 3.12.
+
+Check your default Python version:
+
+```powershell
+python --version
+```
+
+During this setup, Python 3.13 was initially installed. Because the project requires a supported version, Python 3.12 was installed separately.
+
+Verify Python 3.12:
+
+```powershell
+py -3.12 --version
+```
+
+If successful, you should see a Python 3.12 version.
+
+## 3. Create a Virtual Environment
+
+Create a virtual environment using Python 3.12:
+
+```powershell
+py -3.12 -m venv .venv
+```
+
+Activate it:
+
+```powershell
+.\.venv\Scripts\Activate.ps1
+```
+
+Your PowerShell prompt should now begin with:
+
+```text
+(.venv)
+```
+
+## 4. Upgrade pip
+
+Upgrade pip inside the virtual environment:
+
+```powershell
+python -m pip install --upgrade pip
+```
+
+## 5. Install OpenLIFU
+
+Install the local repository in editable mode:
+
+```powershell
+python -m pip install -e .
+```
+
+Verify that OpenLIFU imports successfully:
+
+```powershell
+python -c "import openlifu; print('OpenLIFU imported successfully')"
+```
+
+Expected output:
+
+```text
+OpenLIFU imported successfully
+```
+
+You can also verify that Python is using the local repository:
+
+```powershell
+python -c "import openlifu; print(openlifu.__file__)"
+```
+
+The displayed path should point to the local repository's `src\openlifu` directory.
+
+## 6. Explore the Included Examples
+
+List the example files included with the repository:
+
+```powershell
+Get-ChildItem examples -Recurse -File | Select-Object FullName
+```
+
+The repository includes introductory tutorial files such as:
+
+- `01_Introduction_And_Object_Creation.py`
+- `02_Database_Interaction.py`
+- `03_Solution_Generation_and_Analysis.py`
+
+You can begin exploring these examples without connecting physical hardware.
+
+## 7. Optional Dependencies
+
+Some OpenLIFU functionality uses optional dependencies.
+
+During this setup, missing dependencies produced errors such as:
+
+```text
+ModuleNotFoundError: No module named 'vtk'
+```
+
+```text
+ModuleNotFoundError: No module named 'skimage'
+```
+
+```text
+ModuleNotFoundError: No module named 'trimesh'
+```
+
+The project's `pyproject.toml` defines optional dependency groups for different features, including:
+
+- `mesh`
+- `db`
+- `io`
+- `sim`
+- `cloud`
+- `jupyter`
+
+Before installing individual packages, check which dependency group is appropriate for the functionality you want to use.
+
+## 8. Troubleshooting Dependency Conflicts
+
+While installing additional dependencies, NumPy was upgraded to version 2.x.
+
+However, OpenLIFU required:
+
+```text
+numpy<2
+```
+
+To restore a compatible version:
+
+```powershell
+python -m pip install "numpy<2"
+```
+
+After changing dependencies, verify the installation again:
+
+```powershell
+python -c "import openlifu; print('OpenLIFU imported successfully')"
+```
+
+## 9. Running Without Hardware
+
+OpenLIFU can be explored without connecting physical hardware.
+
+A no-hardware first-day workflow can include:
+
+1. Cloning the repository.
+2. Creating a supported Python environment.
+3. Installing OpenLIFU locally.
+4. Importing OpenLIFU successfully.
+5. Exploring the included tutorial examples.
+6. Working with Python objects and supported simulation-related functionality.
+
+This allows a new contributor to become familiar with the repository before working with physical devices.
+
+## Suggested Screenshots
+
+Before submitting this tutorial, capture screenshots showing:
+
+1. The repository successfully cloned in PowerShell.
+2. The Python 3.12 virtual environment activated.
+3. The successful OpenLIFU import.
+
+Add these screenshots to the documentation in the appropriate location.
+
+## Day 1 Checklist
+
+- [x] Clone the repository
+- [x] Install a supported Python version
+- [x] Create a virtual environment
+- [x] Activate the virtual environment
+- [x] Install OpenLIFU locally
+- [x] Verify that OpenLIFU imports successfully
+- [x] Explore the included examples
+- [x] Document setup friction points
+- [ ] Add screenshots
+- [ ] Test and document a complete simulator/mock workflow
+- [ ] Open a draft pull request
+
+## Next Steps
+
+After completing the initial setup:
+
+1. Read the repository's `README.md`.
+2. Review `CONTRIBUTING.md`.
