 ### Notes on Dependencies
 
-If you intend to evaluate floating-point expressions (using **lambdify**), you should consider linking against **LLVM**. Many users might also benefit from linking against **FLINT**, as it is now LGPL-licensed.

-In general, **sudo** is only required if you are installing to the default prefix (`/usr/local`). We recommend specifying a custom prefix (`--prefix=$HOME/.local`) to avoid requiring administrative privileges, which most users can do without using **sudo**.

-If you're uncomfortable specifying the prefix manually, we suggest using **Conda** or installing the pre-built wheels via **pip** instead of building from source.
