-FoliaFlow is a Minecraft plugin that allows players to using gravity block duplication glitch again in Paper and Folia
+FoliaFlow is a Minecraft plugin that allows players to using gravity block duplication glitch again in folia (paper soon)
 
 ## How is work?
-Whenever a falling sand entity comes close to or hits the end portal, a new falling sand entity is summoned with a velocity that shoots it straight into the portal. However, we encountered a problem when the entity got reset by the safe teleport Paper patch - it lose its velocity. To fix this, we added the velocity back when the entity was in the end.
-
-## ⚠️If you using folia 
-And type of concreate factory collector that use piston full block to stop falling blocks. You should change to slab to prevent block early break follow picture below

+Whenever a falling sand entity comes close to or hits the end portal, a new falling sand entity is summoned with a velocity that shoots it straight into the portal. However, we encountered a problem when the entity got reset by the safe teleport paper patch - it lost its velocity. To fix this, we added the velocity back when the entity was in the end. Another issue we faced was that the entity would instantly turn into a block upon teleportation because it have block below. To solve this, we made the center block of the spawn platform a slab, ensuring that the entity stays in its falling state.
 
 
 ## Installation
 
 To install FoliaFlow, follow these steps:
 
-1. Download the plugin JAR file from the [Modrinth](https://modrinth.com/plugin/foliaflow).
+1. Download the plugin JAR file from the [releases page](https://github.com/Hynse/FoliaFlow/releases).
 2. Copy the JAR file to the `plugins` folder of your Minecraft server.
-3. Restart your server to load the plugin.
-
-## Config flies (config.yml)
-```yml
-# Don't touch this file unless you know what you're doing
-# Default values seems vanilla.
-# If you find values that seems more vanilla please create a PR
-# https://github.com/Hynse/FoliaFlow
-
-# Default value for horizontal_coefficient
-#  - Folia (1.499)
-#  - Paper (2)
-horizontal_coefficient: 1.499
-# -----------------------------------------
-
-vertical_coefficient: -1.7
-spawn_height: 0.08
-
-# Default value for teleport_offset
-#  - Folia (0.5)
-#  - Paper (2.4)
-teleport_offset: 0.5
-# -----------------------------------------

-
-## Permissions
-`foliaflow.reload` for using command `/flowreload` to reload config flies
+3. Restart your server to enable the plugin.
