All these parts are rated for thousands of hours of operation, and I have fully tested OpenClino to run for a minimum of 100 hrs without fault.

-## Design requirements
-
-Clinostats are usually used in biology for plants, cell cultures, and small animals such as fish.
-
-1. OpenClino shall be robust to failures to not harm the animals or samples. 
-2. Openclino must be simple, accessible, and affordable, requiring no machining.
-3. OpenClino should operate in hot and humid environments such as incubators.
-4. OpenClino should operate as a clinostat or RPM.
-
-At the moment it is a work in progress.
-I'm not an electrical engineer so this is 12v. Be careful with your electronics. 
-At the moment it functions as a clino but not a true RPM. The motors can't start a new direction or speed independently.
-You can buy waterproof nema17s and have the electronics outside of the incubator if needed.

+## Convention & Definitions
 
+- X body is the external larger square. 
+- Y body is the internal smaller body.
+- Motor pulleys attach to the motor.
+- X/Y pulleys attach to the body.
+- The "`m2y`" pulley is the one with 2 belts attached.
+- The "`y_turn`" is the bearings bending the long y belt.
+- The "`y_guide`" is the L shaped bracket holding the y pulley.
 
 ## Code
 
-The code is work in progress, it requires the following:
- - control multiple motors separately.
- - acceleration.
- - docs.
- - Implementing the airbus algorithm for variable G.

+# OpenClino Documentation
+
+This document provides reference information about the functions used to control stepper motors in the Arduino project. Each function is described with its purpose, parameters, and behavior.
+
+## Functions
+
+### `void yClockwise(bool foo)`
+
+Sets the direction of the Y-axis motor.
+
+- **Parameters:**
+  - `foo` (bool): If `true`, sets the direction to clockwise; if `false`, sets it to counterclockwise.
+
+---
+
+### `void spin_continuous(float speedRPMX = 60, float speedRPMY = 60, int finalDelay = 100)`
+
+Spins the X and Y motors continuously at specified speeds until a button is pressed.
+
+- **Parameters:**
+  - `speedRPMX` (float, default = 60): Speed of the X-axis motor in RPM.
+  - `speedRPMY` (float, default = 60): Speed of the Y-axis motor in RPM.
+  - `finalDelay` (int, default = 100): Delay in milliseconds after stopping the motors.
+
+---
+
+### `void spin_degs(float degX, float degY, float speedX = 10, float speedY = 10, int finalDelay = 100)`
+
+Spins the X and Y motors by specified degrees at specified speeds.
+
+- **Parameters:**
+  - `degX` (float): Degrees to rotate the X-axis motor.
+  - `degY` (float): Degrees to rotate the Y-axis motor.
+  - `speedX` (float, default = 10): Speed of the X-axis motor in RPM.
+  - `speedY` (float, default = 10): Speed of the Y-axis motor in RPM.
+  - `finalDelay` (int, default = 100): Delay in milliseconds after stopping the motors.
+
+---
+
+### `void RPM()`
+
+Placeholder function for future implementation.
+
+---
+
+### `void calibrate_pulley_teeth()`
+
+Calibrates the pulley teeth by rotating the motors in specific patterns.
+
+---
+
+### `void test_spin_degs_multi()`
+
+Tests the `spin_degs` function with multiple rotations.
+
+---
+
+### `void setup()`
+
+Initializes the Arduino pins and serial communication, and prints a welcome message.
+
+---
+
+### `void loop()`
+
+Main loop that reads the button state and performs actions based on the button press.
+
+- **Behavior:**
+  - Turns off motors when the button is not pressed.
+  - When the button is pressed, it turns on the motors, lights up the built-in LED, and runs calibration and test functions.
