 A small python library with functions to assist engineers.
 
-## Usage
+## Getting Started
 
-### Code:
+- Install using pip:
+
+```
+pip install aero-astro-calc
+```
+
+- Import into your Python project
 
 ```python
 from aero_astro_calc import PlaneStress
+```
 
+## Usage
+
+Make plane stress object:
+
+```python
 stress = PlaneStress(80, -40, 25)
+```
+
+View the stress on a 2D plane:
+
+```python
 stress.plane()
 ```
 
-### Output:
+![Plane Stress example](images/PlaneStress.png)
 
-![Plane Stress example](PlaneStress.png)
+View Mohr's circle of the stresses:
+
+```python
+stress.mohr()
+```
+
