+# Attic Greek (ABNT2)
+
+A polytonic Ancient (Attic) Greek keyboard layout for Brazilian ABNT2 keyboards, built with [Keyman Developer](https://keyman.com/developer).
+
+## 
+
+## Overview
+
+This keyboard allows typing polytonic Attic Greek — including breathings (smooth/rough), accents (acute, grave, circumflex), vowel quantity marks (macron/breve), iota subscript, and dialytika — directly from a standard Brazilian ABNT2 physical keyboard, without needing to remap the underlying OS layout.
+
+It is intended for students and researchers of Ancient Greek philology, philosophy, and classics who work on ABNT2 hardware and want an intuitive, discoverable set of deadkey combinations rather than memorizing raw Unicode code points.
+
+
+## Features
+
+* Full polytonic coverage: smooth (᾿) and rough (῾) breathings, acute, grave, and circumflex accents, iota subscript, and dialytika
+
+* Macron/breve (vowel quantity) combinations for α, ι, υ
+
+* Deadkey-based input: compose diacritics onto a base vowel in any order supported by the ruleset
+
+* On-Screen Keyboard (OSK) layout for visual reference on touch/desktop
+
+## 
+
+## Installation
+
+1. Download and install [Keyman](https://keyman.com) for your platform.
+
+2. Install the `attic\_greek\_abnt2.kmp` package.
+
+3. Select "Attic Greek (ABNT2)" from your Keyman keyboard list.
+
+## 
+
+## Usage
+
+Deadkeys are typed before or after the base vowel (see table below) to compose the desired combination. Refer to the on-screen keyboard (OSK) for the full deadkey map.
+
+## Known limitations
+
+* Macron/breve combinations are currently restricted to α, ι, υ.

+<h1>Welcome to the Attic Greek for ABNT2 keyboard</h1>
+
+<p>For users of the ABNT2 Brazilian Portuguese keyboard, learning this layout will feel intuitive.</p>
+<p>It combines the Greek keyboard layout with the accentuation keys of the Brazilian Portuguese ABNT2.</p>
+<p>For those who know Portuguese and are already familiar with the Attic Greek alphabet and accentuation, learning to use this keyboard will require minimal effort.</p>
+
+<hr>
+<h1>How to type</h1>
+
+<h2> • Main Accentuation Keys:</h2>
+
+<p>The primary accent and diacritic keys are (ç), (~), (´), ([), (]) and (-):</p>
+
+<p>
+(ç): Iota subscript</br>
+(~): Tilde</br>
+(´): Acute and grave accents</br>
+([): Rough breathing</br>
+(]): Soft breathing</br>
+(-): Macron</br>
+</p>
+
+<h2> • How to Type Accents:</h2>
+
+<p>To apply accents and signs, press the accent keys before typing the vowel.</p>
+
+<p>Note: The order of the accent keys does not matter; you can press them in any combination before typing the target letter.</p>
+
+<p>Examples:</p>
+<p>
+To type ῳ, press (ç) followed by ω.<br/>
+To type ῷ, press (ç), (~), and ω.<br/>
+To type ᾧ, press (ç), (~), ([), and ω (and so on).<br/>
+</p>
