# Filament: Custom Content Adder for Fabric Servers<\/p>\n
\n
\n
\n <\/p>\n
 <\/p>\n
filament simplifies adding custom content to Fabric-based Minecraft servers. It allows server owners to add new items, blocks, decorations and even mobs using JSON files\u2014no coding required. Configure a block, item, decoration, or armor, and you’re ready to go!<\/p>\n
Clients can connect to servers using filament without installing any mods, as it relies on a resource pack, item display entities, and packet-based methods. <\/p>\n
Decorations and other features have minimal server performance impact due to their packet-based nature.<\/p>\n
**Use Polymer’s auto-hosting capability to host the resource pack\u2014no third-party server required.**<\/p>\n
