Add OWML mod skeleton and import English translation template

Phase 2 (mod skeleton) + Phase 3 (import English source):

- manifest.json / SlovakTranslation.cs / ILocalizationAPI.cs registering
  "Slovenčina" via xen.LocalizationUtility (Interplanetary Polyglot).
- SlovakTranslation.csproj / .sln building net48 against the OWML and
  OuterWildsGameLibs NuGet packages — no game install needed to compile.
- assets/Translation.xml: English source template (896 KB, 2424 entries,
  keys == values) to be translated into Slovak.
- Project docs (README/PLAN/CLAUDE) and .gitignore.

Build verified: dotnet build -c Release stages a loadable mod folder.

-# Outer-Wilds-SK-Translation-Mod
+# Outer Wilds — Slovenský preklad / Slovak Translation Mod
 
+> **Neoficiálny slovenský preklad hry Outer Wilds** (základná hra + rozšírenie
+> *Echoes of the Eye*). Pridáva do hry jazyk **Slovenčina**.
+>
+> *An unofficial Slovak (slovenčina) translation mod for Outer Wilds, covering
+> the base game and the Echoes of the Eye DLC.*
+
+**Stav / Status:** 🚧 **Work in progress** — the mod scaffold and translation are
+being built. See [`PLAN.md`](PLAN.md) for the roadmap.
+
+Outer Wilds officially ships in 12 languages; Slovak is not one of them. This mod
+adds it as a new selectable language using the community localization framework —
+no changes to the game's own files are required.
+
+---
+
+## How it works
+
+The mod is a small [OWML](https://github.com/ow-mods/owml) mod that registers a
+new language through **[Interplanetary Polyglot / Localization Utility](https://outerwildsmods.com/mods/interplanetarypolyglot/)**
+(`xen.LocalizationUtility`). All translated text lives in a single
+`assets/Translation.xml`; the utility swaps the game's strings for the Slovak ones
+at runtime.
+
+## Installation
+
+1. Install the **[Outer Wilds Mod Manager](https://outerwildsmods.com/mod-manager/)**.
+2. Install this mod through the Mod Manager. Its dependency **Interplanetary
+   Polyglot** (`xen.LocalizationUtility`) will be pulled in automatically.
+3. Launch the game via the Mod Manager.
+4. In **Settings → Language**, choose **Slovenčina**.
+   - Tip: the optional [Language Swap](https://outerwildsmods.com/mods/languageswap/)
+     mod lets you switch language in-game with `Ctrl+L`.
+
+> Until the first release is published, the mod is not yet in the Mod Manager
+> database — see [`PLAN.md`](PLAN.md) for how to build it from source.
+
+## Contributing / Prispievanie
+
+Translation fixes are very welcome — the goal is natural, consistent Slovak.
+
+- **Report** mistranslations or awkward phrasing as an issue.
+- **Edit** only the `<value>` of each entry in `assets/Translation.xml`.
+  **Never change the `<key>`** — it is the English identifier the game matches on.
+- Preserve all inline formatting exactly, e.g. `&lt;color=orange&gt;…&lt;/color&gt;`,
+  `&lt;i&gt;`, and speaker prefixes like `POKE:`.
+- Follow the terminology in `docs/glossary.md` so names (Nomai, the Eye, Ash Twin
+  Project, …) stay consistent across the whole game.
+
+See [`CLAUDE.md`](CLAUDE.md) for the full conventions and repo layout.
