-# [DIY Kit Name] — Build Guide
-
-**Version:** [v1.0]  
-**Date:** [YYYY-MM-DD]  
-**Author:** [Name / Contact]  
-
----
-
-## 1. Introduction
-- What this kit does (short description).  
-- Skill level required (Beginner / Intermediate / Advanced).  
-- Estimated build time: [X hours].  
-- Tools required: [Soldering iron, multimeter, etc.].  
-
----
-
-## 2. Circuit Description
-### 2.1 General Idea
-- Short explanation of the concept.  
-- Example: *The kit demonstrates low-power control using an ATtiny85 microcontroller. It blinks an LED in Morse code and sleeps when ambient light is detected.*  
-
-### 2.2 Annotated Schematic
-*(Insert schematic image exported from KiCad, e.g., as PNG or PDF)*  
-
-Use numbered blocks for explanation. Example:  
-
-**Figure 1: Schematic with annotation numbers**

-| Block | Circuit Section   | Description                                                                                           |
-|:-----:|:------------------|:------------------------------------------------------------------------------------------------------|
-| 1     | Power Supply      | 2×AA batteries → DC/DC regulator (U1) → 5 V rail. Decoupling capacitors (C1, C2) smooth the voltage.  |
-| 2     | Controller        | ATtiny85 (U2) running firmware. Pull-up resistors (R1, R2) ensure stable inputs.                      |
-| 3     | LED Output        | LED D1 driven by PB0. Current limited by R3 (330 Ω).                                                  |
-| 4     | Light Sensor      | LED D2 reverse biased → generates photocurrent. Read on PB2.                                          |
-| 5     | Programming Header| ISP 6-pin header for flashing firmware.                                                               |
-| 6     | Test Points       | Labeled pads J1–J3 for debugging with a multimeter.                                                   |

-
-### 2.3 Functional Flow
-- Add a block diagram showing logic signal flow (KiCad → export block diagram or draw in Mermaid).  
-- Example: *Battery → DC/DC → ATtiny85 → LED driver → LED.*  
-
----
-
-## 3. Mechanical Parts
-### 3.1 2D CAD Files
-- Mechanical drawings in DXF for front panel / housing.  
-- Dimensions, hole positions, and cut-outs for connectors.  
-
-### 3.2 3D Models
-- STL/STEP files for 3D printing, if available.  
-- Assembly orientation, support recommendations.
