+# Introduction
 
 `RIP` is a library that allows the resolving and installing of Python [PyPI](https://pypi.org/) packages from Rust into a virtual environment.
 It's based on our experience with building [Rattler](https://github.com/mamba-org/rattler) and aims to provide the same
 experience but for PyPI instead of Conda.
-It should be fast and easy to use. Like Rattler, this library is not a package manager itself but provides the low-level plumbing to be used in one.

+## What should I use this for?

+Like Rattler, `RIP` should be fast and easy to use. This library is not a package manager itself but provides the low-level plumbing to be used in one.
+To see an example of this take a look at our package manager: [pixi](https://github.com/prefix-dev/pixi)
 
 `RIP` is based on the quite excellent work of [posy](https://github.com/njsmith/posy) and we have tried to credit
 the authors where possible.
 
 # Showcase
 
-Let's resolve the `flask` python package.
-We've added a small binary in `rip_bin` to showcase this:

-![flask-install](https://github.com/prefix-dev/rip/assets/4995967/5b0356b6-8e06-47bb-9424-94b3fdd9da09)
+`RIP` has a very incomplete pip-like binary that can be used to test package installs.
+Let's resolve and install the `flask` python package. Running `cargo r install flask /tmp/flask` we get something like this:
 
-This showcases the downloading and caching of metadata from PyPI. As well as the package resolution using our solver, more on this below.
-We cache everything in a local directory so that we can re-use the metadata and don't have to download it again.

-# Installation
-
-We have added very simple installation support for the resolved packages.
-For testing purposes exclusively, we have added an `install` command to the `rip_bin` binary.
-E.g. `cargo r -- install flask /tmp/flask` to create a venv and install the flask and it's into it.
-There is no detection of existing packages yet.
+This showcases the downloading and caching of metadata from PyPI. As well as the package resolution using our incremental SAT solver: [Resolvo](https://github.com/mamba-org/resolvo), more on this below.
+Finally, after resolution it installs the package into a venv.
+We cache everything locally so that we can re-use the PyPi metadata.

 More intricacies of the PyPI ecosystem need to be implemented, see our GitHub issues for more details.

+## Resolving
 
 We have integrated the stand-alone packaging SAT solver [Resolvo](https://github.com/mamba-org/resolvo), to resolve pypi packages.
 This solver is incremental and adds packaging metadata during resolution of the SAT problem.
 This feature can be enabled with the `resolvo` feature flag.
 
+## Installation
+
+We have very simple installation support for the resolved packages.
+This should be used for testing purposes exclusively
+E.g. `cargo r -- install flask /tmp/flask_env` to create a venv and install the flask and it's into it.
+After which you can run:
+   1. `/tmp/flask_env/bin/python` to start python in the venv.
+   2. `import flask #`, this should import the flask package from the venv.
+There is no detection of existing packages in the venv yet, although this should be relatively straightforward.
