 ## Requirements
 `lean-smt` depends on [`lean-cvc5`](https://github.com/abdoo8080/lean-cvc5) FFI,
-which currently only supports Linux (x86_64) and macOS (AArch64).
+which currently only supports Linux (x86_64) and macOS (AArch64 and x86_64).
 
 ## Usage
 To use `lean-smt` in your project, add the following line to your list of
 dependencies in `lakefile.lean`:
 ```lean
-require smt from git "https://github.com/ufmg-smite/lean-smt.git"@"main"
+require smt from git "https://github.com/ufmg-smite/lean-smt.git" @ "main"

+  else if System.Platform.isOSX then "libc++.dylib"
+  else "libstdc++.so.6"
+
+package foo where
+  moreLeanArgs := #[s!"--load-dynlib={libcpp}"]
+  moreGlobalServerArgs := #[s!"--load-dynlib={libcpp}"]
 ```
 `lean-smt` comes with one main tactic, `smt`, that translates the current goal
 into an SMT query, sends the query to cvc5, and (if the solver returns `unsat`)
