-# WowPresence
-Native Discord Rich Presence for World of Warcraft 1.12.1 (build 5875) and compatible clients.
+# 🎮 WowPresence
+
+Native Discord Rich Presence for **World of Warcraft 1.12.1 (build 5875)** and compatible clients.
+
+Focused on **simple installation, read-only game sampling and native Discord IPC**.
+
+> WowPresence targets **WoW 1.12.1 / build 5875-compatible client environments**.
+
+## 🔌 Requirements
+
+- **World of Warcraft 1.12.1 (build 5875)** or a compatible client
+- **Discord Desktop**
+- A compatible DLL loader such as **VanillaFixes**
+- A free **Discord Application ID**
+
+The DLL only reads character status from the game. Discord communication is handled by the separate `WowPresence.exe` companion process.
+
+## 📦 Installation
+
+1. Download **`WowPresence.zip`** from Releases.
+2. Extract the ZIP directly into your WoW game directory.
+3. Open:
+
+```text
+WowPresence\discord_application_id
+```
+
+4. Replace the placeholder with **your numeric Discord Application ID**.
+5. Add `WowPresence.dll` to your VanillaFixes `dlls.txt`.
+6. Launch WoW normally through VanillaFixes.
+
+After extraction, the relevant files should look like this:
+
+```text
+<WoW folder>\
+├─ WowPresence.dll
+├─ WowPresence.exe
+└─ WowPresence\
+   ├─ discord_application_id
+   └─ discord_broadcast_flags
+```
+
+`WowPresence.exe` is started automatically by the DLL and normally does **not** need to be launched manually.
+
+The runtime JSON and log files are created automatically inside the same `WowPresence` folder.
+
+When WowPresence is installed through **Modernization Tool**, the same binaries automatically use:
+
+```text
+<WoW folder>\.modernization_tool\WowPresence\
+```
+
+instead. No separate build is required.
+
+## 🛰️ Discord Application ID
+
+For **OctoWoW**, you can use the preconfigured Discord Application ID:
+
+```text
+1544072796098011176
+```
+
+This is the same Application ID automatically configured by **Modernization Tool**.
+
+If you want to use your own Discord application instead:
+
+
+1. Open the **Discord Developer Portal**: https://discord.com/developers/applications
+2. Create a **New Application**.
+3. Give it the name you want Discord to display.
+4. Open **General Information**.
+5. Copy the **Application ID**.
+6. Paste only that numeric ID into:
+
+```text
+WowPresence\discord_application_id
+```
+
+Example:
+
+```text
+123456789012345678
+```
+
+No Discord Client Secret, bot token or bot account is used or required.
+
+If `discord_application_id` is missing or invalid, Rich Presence remains disabled and the reason is written to `WowPresence\WowPresence.log`.
+
+## ✨ Features
+
+- Character name and guild display.
+- Level and class display.
+- Race and faction display.
+- Current zone display resolved from the client AreaTable instead of heuristic text-address scanning.
+- Stable elapsed-session timer across character changes.
+- Automatic companion startup.
+- Exact WoW process tracking.
+- Read-only game-memory sampling.
+- Native Discord IPC.
+- Optional privacy flags for individual character fields.
+- No bot, Client Secret or external service required.
+
+## 🔧 Compatibility
+
+### Tested
+
+- **OctoWoW** — WoW 1.12.1 / build 5875 based client
+
+### Expected compatible
+
+- **World of Warcraft 1.12.1 build 5875**
+- Private-server clients preserving the relevant 1.12.1 client memory layout
+
+### Not compatible
+
+- WoW Classic Era 1.14.x
+- The Burning Crusade Classic
+- Wrath of the Lich King Classic
+- Retail World of Warcraft
+
+Other modified 1.12.1 clients should be considered **untested until verified**.
+
+## ⚙️ How it works
+
+```text
+WoW
+ └─ WowPresence.dll
+      ├─ read-only character sampling
+      ├─ Area ID → AreaTable zone resolution
+      ├─ WowPresence\discord_wow_status.json
+      └─ starts WowPresence.exe
+             └─ Discord local IPC
+```
+
+Zone names are resolved from the player's current AreaTable ID, matching the client's own zone data and avoiding internal map tokens such as `H32D` or `HLVA`.
+
+The DLL does not communicate directly with Discord.
+
+The companion executable does not read or write WoW memory.
+
+Runtime files are kept together in one of these locations:
+
+**Standalone installation:**
+
+```text
+<WoW folder>\WowPresence\
+├─ discord_application_id
+├─ discord_broadcast_flags
+├─ discord_wow_status.json
+└─ WowPresence.log
+```
+
+**Installed through Modernization Tool:**
+
+```text
+<WoW folder>\.modernization_tool\WowPresence\
+├─ discord_application_id
+├─ discord_broadcast_flags
+├─ discord_wow_status.json
+└─ WowPresence.log
+```
+
+If the Modernization Tool managed folder exists, WowPresence automatically prefers it. Otherwise it uses the standalone `WowPresence` folder.
+
+## 🔒 Privacy flags
+
+The included file:
+
+```text
+WowPresence\discord_broadcast_flags
+```
+
+controls which character details are published to Discord.
+
+| Value | Field |
+| ---: | --- |
+| 1 | Name |
+| 2 | Guild |
+| 4 | Faction |
+| 8 | Class |
+| 16 | Level |
+| 32 | Zone |
+| 63 | All fields |
+
+The release package uses `63` by default.
+
+If the file is deleted, WowPresence also defaults to all supported fields.
+
+## 🛡️ Administrator privileges
+
+Discord and WoW should run with matching privilege levels.
+
+If Discord runs as administrator, WoW must also run as administrator for local Rich Presence IPC to work reliably.
+
+Running both normally is recommended unless elevation is required by the local setup.
+
+## 🛠️ Building
+
+WowPresence targets **32-bit x86 Windows**, matching WoW 1.12.1.
+
+With an x86 MSVC developer environment:
+
+```bat
+cl /nologo /O2 /MT /W3 /LD src\WowPresence.c /Fe:WowPresence.dll /link /INCREMENTAL:NO
+cl /nologo /O2 /MT /W3 src\WowPresenceLauncher.c user32.lib /Fe:WowPresence.exe /link /SUBSYSTEM:WINDOWS /INCREMENTAL:NO
+```
+
+GitHub Actions builds:
+
+- `WowPresence.dll`
+- `WowPresence.exe`
+- `WowPresence.zip`
+
+The ZIP includes the ready-to-edit `WowPresence` configuration folder.
+
+Tags matching `v*` can publish these files as a GitHub Release.

+# WowPresence v1.2
+
+## Changes
+
+- Reworked zone detection to use the player's real AreaTable ID.
+- Zone names are now resolved from `AreaTable.dbc` instead of selecting the first plausible string from several client addresses.
+- Prevents internal map/area tokens such as `H32D` and `HLVA` from being published as Discord zone names.
+- Uses the client's active localized AreaTable name when available, with a safe populated-locale fallback.
+- Keeps WowPresence fully standalone; ClassicAPI is not required.
+- Modernization Tool installations continue to use `.modernization_tool\WowPresence\` automatically.
+
+## Included
+
+- `WowPresence.dll`
+- `WowPresence.exe`
+- `WowPresence.zip` ready-to-install standalone package

+# Third-Party Notices
+
+WowPresence contains original project code maintained by Dusk-92 and uses compatibility knowledge related to World of Warcraft 1.12.1 and Discord local Rich Presence IPC.
+
+## IchaLaunch
+
+The development of WowPresence was inspired in part by the character-status / Discord Rich Presence implementation in:
+
+- Project: IchaLaunch
+- Author / maintainer: brutaliccus
+- Repository: https://github.com/brutaliccus/IchaLaunch
+
+IchaLaunch was used as a technical reference during development, particularly for understanding a working WoW 1.12.1 character-status sampling approach.
+
+The current WowPresence implementation is maintained separately and has been independently reworked. No IchaLaunch binary is included in this repository.
+
+At the historical IchaLaunch revision reviewed during development, no explicit LICENSE, LICENSE.md, or COPYING file was present. This notice therefore records provenance and credit; it should not be interpreted as granting rights on behalf of the IchaLaunch author.
+
+## ClassicAPI technical reference
+
+AreaTable and current-player-area client layout details were cross-checked against:
+
+- Project: ClassicAPI
+- Repository: https://github.com/brues-code/ClassicAPI
+
+ClassicAPI is used as a technical/reference source for documented WoW 1.12.1 client structures. WowPresence does not require, load, or call ClassicAPI.
+
+## World of Warcraft client compatibility data
+
+WowPresence uses client-layout information and memory offsets associated with World of Warcraft 1.12.1 build 5875. Such compatibility information has been documented in multiple community projects over the years.
+
+These values and client structures are used solely to locate read-only character status information in a compatible running client.
+
+## Discord
+
+WowPresence communicates with the locally running Discord desktop client through Discord's local IPC / Rich Presence protocol.
+
+Discord is a trademark of Discord Inc. WowPresence is not affiliated with or endorsed by Discord Inc.
+
+## Blizzard Entertainment / World of Warcraft
+
+World of Warcraft, Warcraft, Blizzard, and related names and marks are trademarks or registered trademarks of Blizzard Entertainment, Inc.
