 After installing fabric for 1.14, you will need to place the OptiFabric mod jar as well as the optifine installer in the mods folder.
 
-Note currently only fabric api 0.2.7 is supported, you can download it from [here](https://minecraft.curseforge.com/projects/fabric/files/2702281). This will be fixed soon.
+Fabric API 0.2.7 is recommended, you can download it from [here](https://minecraft.curseforge.com/projects/fabric/files/2702281). Newer (0.3.0+) versions may have issues with shaders, if you know how to fix this please get in contact, thanks.
