-# Language Server Details (Serena AUTO-DOWNLOADS these on first startup):
-#   - csharp: Uses Microsoft.CodeAnalysis.LanguageServer (Roslyn) - same engine as VS Code's C# extension
-#     Downloads from Azure NuGet feed; also downloads .NET 9 runtime if needed
-#     ⚠️ KNOWN ISSUE: Fails on T-Mobile Home Internet due to IPv6 routing issues to Azure blob storage
-#   - csharp_omnisharp: Uses OmniSharp (alternative) - also auto-downloads
-#   - cpp: Uses clangd (auto-downloads v19.1.2 on Windows/Mac; Linux needs `apt install clangd`)
+#   - For Free Pascal/Lazarus, use pascal
 # Special requirements:
-#   - csharp: Requires the presence of a .sln file in the project folder.
+#   Some languages require additional setup/installations.
+#   See here for details: https://oraios.github.io/serena/01-about/020_programming-languages.html#language-servers
 # When using multiple languages, the first language server that supports a given file will be used for that file.
 # The first language is the default language and the respective language server will be used as a fallback.
 # Note that when using the JetBrains backend, language servers are not used and this list is correspondingly ignored.
-#
-# T-Mobile IPv6 workaround: Use csharp_omnisharp instead of csharp if you see Azure NuGet download errors.
-# The issue is that Python urllib prefers IPv6, and T-Mobile's IPv6 routing to Azure blob storage is broken.
