-## Build
+## TIPS
 
+### Linux support
+
+You have 2 choice to run on Linux. If you don't need font operation, use `SkiaSharp.NativeAssets.Linux.NoDependencies`.
+
+1. Use `SkiaSharp.NativeAssets.Linux` package. In this case, you need to install `libfontconfig1` via apt or others.
+1. Use `SkiaSharp.NativeAssets.Linux.NoDependencies` 2.80.2 or above. In this case, you don't need `libfontconfig1`.
+
+SkiaSharp.NativeAssets.Linux.NoDependencies still can draw text, however can't search font cased on character or other fonts.
