+# Play From the Fog Reimagined
+
+**Server:** `minecraft.ayush-jain.dev`  
+**Pack:** From the Fog Reimagined **6.3.2** by SoumXD  
+**Minecraft:** 1.20.1 · Forge 47.4.10 · Java 17
+
+## Install once
+
+1. Open your launcher’s modpack installer. For offline-name accounts, [SKlauncher 4.0](https://docs.skmedix.pl/4.0/) supports CurseForge packs and automatic Java setup. Its 4.0 release is currently beta. If you use Microsoft sign-in, the [CurseForge app](https://www.curseforge.com/download/app) can install the pack directly.
+2. Search **From the Fog Reimagined** by **SoumXD**, select **6.3.2**, and install the whole pack. [Exact official client release](https://www.curseforge.com/minecraft/modpacks/from-the-fog-reimagined/files/9191040).
+3. Launch that pack. Give the game 6 GB of memory if your computer has room; the pack author lists 4 GB as the client minimum. Shaders are optional—turn them off if performance is poor.
+4. Multiplayer → Add Server → `minecraft.ayush-jain.dev`.
+
+Use the exact username the admin approved, including capitalization. Start with `aryan` or `jainster` as appropriate. Ask the admin to approve any additional name in CraftDeck → Access & Auth immediately before your first join.
+
+On first join, follow the server prompt: `/login YOUR_PASSWORD YOUR_PASSWORD`. On later joins: `/login YOUR_PASSWORD`. Choose your own password in the game; do not send it to the admin or reuse an important account password. If the registration window expires, the admin can reopen it in CraftDeck.
+
+## If joining fails
+
+- **Not whitelisted:** check the exact username and ask the admin to reopen approval.
+- **Missing/incompatible mods:** launch the complete **6.3.2** pack, rather than vanilla or a standalone From the Fog datapack. Both sides must use 1.20.1 Forge.
+- **Out of memory / slow:** allocate memory in this pack’s launcher settings and disable shaders first.
+- **Cannot connect:** ask the admin to check the Minecraft container and TCPShield route. The CraftDeck admin address is private and is not the game server address.
+
+The server uses the pack author’s matching server pack, plus a server-only login mod. Friends do not need to copy server files or install that login mod. Download pack content from the author through your launcher; no separate mod ZIP collection or hosted mirror is needed.
+
+This is the official Reimagined pack baseline. An exact CaseOh-specific mod/shader list has not been verified.
