 Precompiler allows you to reduce the latency of the first execution of Julia code.
-It is applicable both for package developers and "ordinary users"; for the latter, it can be viewed as an
-alternative to [PackageCompiler](https://github.com/JuliaLang/PackageCompiler.jl), particularly on Julia 1.9 and higher
-where both can be used to cache "native code."
-Nevertheless, the two are not identical: the primary differences between Precompiler and PackageCompiler are:
+**It is applicable for package developers and for "ordinary users" in their personal workflows.**
 
-- only Precompiler can be used by *package developers* to ensure a better experience for your users
+To learn how to use Precompiler, see the [documentation](https://JuliaLang.github.io/Precompiler.jl/stable/).
+
+## Precompiler and PackageCompiler
+
+Particularly on Julia 1.9 and higher, Precompiler allows dramatic reduction in "time to first execution" (TTFX).
+In this respect, it shares goals with (and performs similarly to) [PackageCompiler](https://github.com/JuliaLang/PackageCompiler.jl).
+Nevertheless, the two are not identical:
+
+- only Precompiler can be used by *package developers* to ensure a better out-of-box experience for your users
 - only Precompiler allows you to update your packages without needing to rebuild Julia
 - only PackageCompiler dramatically speeds up loading time (i.e., `using ...`) for all the packages
 
-Precompiler started as [SnoopPrecompile](https://github.com/timholy/SnoopCompile.jl/tree/master/SnoopPrecompile), but
-it differs in naming and in how one disables precompilation.
+## History (origins as SnoopPrecompile)
+
+Precompiler is the successor to [SnoopPrecompile](https://github.com/timholy/SnoopCompile.jl/tree/master/SnoopPrecompile).
+Precompiler differs in naming and in how one disables precompilation, but is otherwise a drop-in replacement.
