 > Approximate floating point equality comparisons and assertions for the Rust Programming Language.
-
-This is a fork of the popular [approx](https://github.com/brendanzab/approx) crate which extends the
-functionality of `approx` by implementing many of the PRs of the original crate.
-It also provides derive macros via `approx-derive`
-
-## Replace `approx`
-To act as a drop-in replacement for [approx](https://github.com/brendanzab/approx), one can use the
-renaming option provided by cargo.
-
-```toml
-# Cargo.toml
-[dependencies]
-approx = { package = "approxim", version = "CURRENT_VERSION" }
-```
-Note that no further changes are required. Derive macros should also work with this workaround.
