+# MCC Development Workflow
+
+## Project Overview
+- Repo: `~/Minecraft/Minecraft-Console-Client` (env var `$MCC_REPO`)
+- Solution: `MinecraftClient.sln` (projects: `MinecraftClient` + `ConsoleInteractive`)
+- Build: `dotnet build MinecraftClient.sln -c Release`
+- Servers: `~/Minecraft/Servers/` (env var `$MCC_SERVERS`)
+
+## Typical Debug Workflow
+1. `~/Minecraft/Servers/start-server.sh 1.20.6-Vanilla` (background)
+2. Wait for "Done" in server output
+3. Build: `dotnet build $MCC_REPO/MinecraftClient.sln -c Release`
+4. Run MCC: `cd $MCC_REPO && MCC_FILE_INPUT=1 dotnet run --project MinecraftClient -c Release -- CursorBot - localhost 2>&1`
+5. RCON: `mc-rcon "op CursorBot"`
+6. MCC cmd: `echo "inventory player list" >> $MCC_REPO/mcc_input.txt`
+7. Read terminal file to see output
+8. Kill MCC → rebuild → repeat
+
+## Timing Reference
+| Operation | Typical Duration |
+|-----------|-----------------|
+| MCC startup → join server | ~1s |
+| FileInput command → response | <500ms |
+
+## Official Minecraft Server Source (Decompiled)
+`$MCC_REPO/MinecraftOfficial/` contains decompiled official server code for protocol reference.
+When investigating protocol details (packet structure, field order, NBT format, etc.),
+look at the corresponding version's decompiled source as authoritative reference.
