+### Bedrock issue
+For server using geyser, bedrock player cannot use custom "recipes" in the anvil.
+This is cannot be fixed on geyser or my side.
+
+### Plugin Compatibility
+Here is various plugins that had issues with CustomAnvil 
+where efforts was made for compatibility and should be working right:
+
+some of them are cool I recommend checking them out !
+
+## Supported By CustomAnvil
+These plugins have compatibility handled by custom anvil. seek help on custom anvil and do not bother these developers
+
+#### Enchantment plugins
+- [ExcellentEnchants](https://www.spigotmc.org/resources/excellentenchants-%E2%AD%90-75-vanilla-like-enchantments.61693/):
+  Use ExcellentEnchants item type
+
+- [EcoEnchant](https://www.spigotmc.org/resources/ecoenchants-%E2%AD%95-250-enchantments-%E2%9C%85-create-custom-enchants-%E2%9C%A8-essentials-cmi-support.79573/):
+  Need to use /anvilconfigreload or a server restart to add newly added enchantment.
+  Use EcoEnchant restriction system but new restriction can be added in custom anvil
+
+- [Enchantment²](https://www.spigotmc.org/resources/enchants-squared-the-enchantsplus-rewrite-custom-enchantments-that-act-like-vanilla-ones.86747/):
+  Support by Custom Anvil but still experimental. Automatic configuration. Plugin is not actively developed anymore
+
+#### Anvil Mechanics
+- [Disenchantment](https://www.spigotmc.org/resources/disenchantment-1-21-1-1-20-6-new-book-splitting-mechanics.110741/)
+  Partially use Custom Anvil maximum XP settings (>= 6.1.5)
+
+- [HavenBags](https://www.spigotmc.org/resources/havenbags-shulker-like-player-bound-bags-1-17-1-21-4.110420/)
+  For bag upgrade and skin via anvil. (version >= 1.31.0)

+
+### Known Partially Incompatible
+- [UberEnchant](https://modrinth.com/plugin/uberenchant) 
+  Anvil handling as they are doing something similar to CustomAnvil.
+It is by no mean there faults and I recomend checking them out
+
+- [SuperEnchant](https://modrinth.com/plugin/superenchants) 
+  Reported potential incompatibility
+
+- [AdvencedEnchantments](https://ae.advancedplugins.net/) 
+  Paid plugin I do not own as I did not get commissioned for support.
+  may be able to use api but cannot test on my side
+
+If you like Custom Anvil to support a specific plugin (custom enchant or anvil mechanic).
+You can ask, but please note implementing compatibility will be considered
+as low priority as I work for the plugin as an hobby on my free time for free.
