-# About
-TAB aims to be a superior all-in-one minecraft plugin for displaying information that outperforms all 
-similar plugins in terms of features, performance and compatibility.  
-More information can be found at [Why TAB?](https://github.com/NEZNAMY/TAB/wiki/Why-TAB%3F) wiki page.
+# TAB-OG

-# Compiling
-Compilation requires JDK 17 and up.  
-To compile the plugin, run `./gradlew build` from the terminal.  
-Once the plugin compiles, grab the jar from `/jar/build/libs/` folder.  
-The universal jar contains all modules for all supported platforms.
+TAB-OG is a soft fork of [TAB](https://github.com/NEZNAMY/TAB) for
+[TrueOG Network](https://true-og.net/), based on upstream commit `93cfd74`.

-# Documentation
-You can find everything about the plugin on the [Wiki](https://github.com/NEZNAMY/TAB/wiki). This includes a detailed description
-of all features, as well as information regarding compatibility or limitations of each feature.  
+Differences from upstream TAB:
+- Versioned `5.9.9` (upstream is on `6.x`), targeting Purpur 1.19.4 serving 1.8–1.21.11
+  clients through ViaVersion, ViaBackwards, and ViaRewind.
+- Builds only Bukkit `v1_19_R3`, BungeeCord, and Velocity; drops Fabric, Forge, NeoForge,
+  and the unused Bukkit/Paper NMS modules.
+- Uses LuckPerms `5.5` (Vault removed) with a GraalVM JDK 17 toolchain, producing one
+  universal shaded JAR.
+- TrueOG compatibility fixes: [Vanish-OG](https://git.trueog.net/trueog/Vanish-OG), the
+  [AFK-OG](https://git.trueog.net/trueog/AFK-OG) indicator, legacy scoreboard team colors,
+  and disabled scoreboard number formats.
+- Legacy (1.8–1.12.2) nametag rendering: over-head names drop the rank brackets (the
+  tablist keeps them), sit one space after the rank in its color, bold the AFK indicator
+  for every client, and fit within the 16-character team prefix/suffix limits. A bold
+  rank is kept only when the whole tag can render bold — legacy clients width-count
+  everything after `§l` as bold and never receive a `§r`, so a plain-rendered name after
+  a bold rank pads the nametag end with phantom pixels; when it cannot fit, bold is
+  stripped over-head. Keeping bold requires `add-teamcolor-to-prefix: false` in the
+  ViaBackwards config, otherwise the appended team color un-bolds the name again.
+- Ships live TrueOG Network config values.

-# Issues
-The [Issues](https://github.com/NEZNAMY/TAB/issues) section is an issue tracker for all the kind of problems covered in issue templates.
-Please refrain from attempting to use it to receive help with your server, such issues will be closed immediately.  
-When opening an issue, provide as much information as possible. The difference between a bug getting fixed in 1 week vs 1 hour
-is in quality of the report. Bug reports where steps to reproduce are "idk" have no value and will not help to get the bug fixed at all.

-See [CONTRIBUTING.md](https://github.com/NEZNAMY/TAB/blob/master/CONTRIBUTING.md)
+Build with `./gradlew build` (JAR in `jar/build/libs/`). Requires LuckPerms; bold legacy
+nametags additionally require ViaBackwards with `add-teamcolor-to-prefix: false`.

- * Scoreboard implementation using Bukkit API (1.5.2+). It has several issues:

- *      While this may not seem like a problem, it enforces those
- *      limits even for 1.13+ players (if using ViaVersion).<p>
- * #2 - Modern versions no longer have any limits, but md_5
- *      decided to add some random limits for absolutely no reason
- *      at all. Scoreboard title received a random 128 characters
- *      limit including color codes. Together with the almighty bukkit
- *      RGB format using 14 characters for 1 color code, this makes
- *      gradients just impossible to use. Team prefix/suffix also
- *      received a 64 characters limit (excluding color codes at least),
- *      however that might not be enough for displaying a line of text
- *      in sidebar, which would require splitting the text into prefix
- *      and suffix, which is just begging for bugs to be introduced.<p>
- * #3 - Other plugins can decide to put players into their own
- *      scoreboard, automatically destroying all visuals made by the
- *      plugin. They might also put all players into the same scoreboard,
- *      making per-player view of teams, especially sidebar not working.<p>
