## 2. Getting Started
### 2.1. Prerequisites
1. Python 3.11 or above
2. SAP2000 v24 or higher### 2.2. Installation
#### 2.2.1. Production
##### 2.2.1.1. Install directly from repo
Clone repo and Install with flit
```bash
git clone https://github.com/rpakishore/ak_sap.git
cd ak_sap
pip install flit
```- If you want just the base package:
```bash
flit install --deps production
```- Alternatively, if you also want to include the optional streamlit gui:
```bash
flit install --deps production --extras gui
```##### 2.2.1.2. Install from Pypi release

```Note: The Pypi version does not ship with the optional streamlit gui
#### 2.2.2. Development
Download the git and install via flit
```bash
git clone https://github.com/rpakishore/ak_sap.git
cd ak_sap
pip install flit
flit install --pth-file
```Updating Docs:
- Update the [Usage.ipynb](./documentation/Usage.ipynb).
- Open `cmd.exe` to run```bash
update-doc
```## 3. Usage
