 # sophus-rs
 
-This library is in an early development stage - hence API is highly unstable.
+sophus-rs is a Rust library for 2d and 3d geometry for Computer Vision and Robotics applications.
+It is a spin-off of the [Sophus](https://github.com/strasdat/Sophus) C++ library which
+focuses on **Lie groups** (e.g. rotations and transformations in 2d and 3d).
 
-Sophus-rs currently requires rust nightly. The only nightly feature it uses is `portable-simd`.
-It is the intention to move to rust stable once `portable-simd` is stabilized. There is no current
-plan to depend on other nightly features.
+In addition to Lie groups, sophus-rs also includes other geometric/maths concepts such unit vector,
+splines, image classes, camera models as well as a other utilities such as a non-linear least
+squares optimization.
+
+## Status
+
+This library is in an early development stage - hence API is highly unstable. It is likely that
+existing features will be removed or changed in the future.
+
+However, the intend is to stride for correctness, facilitated using a comprehensive test suite.
+
+## Building
+
+sophus-rs builds on stable.
+
+```toml
+[dependencies]
+sophus = "0.7.0"
+```
+
+To allow for batch types, such as BatchScalarF64, the 'simd' feature is required. This feature
+depends on [`portable-simd`](https://doc.rust-lang.org/std/simd/index.html), which is currently
+only available on [nightly](https://doc.rust-lang.org/book/appendix-07-nightly-rust.html). There
+are plans to use any other nightly features.
+
+```toml
+[dependencies]
+sophus = { version = "0.7.0", features = ["simd"] }
+```
