 ## Why?
 
-- Your OS's package manager doesn't contain the latest (or multiple) $language versions
-  - And/or you don't trust random APT repositories, AUR packages, etc.
-- You want an OS independent way to install and switch between $language versions
-  - And/or if you don't want to remember how to use `update-alternatives`, `archlinux-java`, etc.

+  - And/or if you don't want to remember / forget how to use `update-alternatives`, `archlinux-java`, etc.
 - You are tired of installing and configuration version managers for every single language
-- You believe any of the following is overkill, slow, bloated, or is poorly coded
-  - [Nix](https://nixos.org)
-  - [Guix](https://guix.gnu.org/en/download)
-  - [asdf](https://github.com/asdf-vm/asdf)
-  - [sdkman](https://github.com/sdkman/sdkman-cli)
-  - [Docker](https://www.docker.com) (or containers in general)
+  - And/or you think each version manager comes with its own class of bugs / bad dx, etc.
+
+I didn't like existing solutions such as [asdf](https://github.com/asdf-vm/asdf) or [sdkman](https://github.com/sdkman/sdkman-cli). asdf was too buggy and I disliked the coding style and architecture. sdkman is better but it felt too bloated, complex, and Java-centric. Other solutions like [Nix](https://nixos.org), [Guix](https://guix.gnu.org/en/download), and [Docker](https://www.docker.com) solve the solutions in some way, but aren't optimal
 
 ## Features
 
 - Optionally configurationless
 - Can install any language with pure Bash
-- Clean Bash code (uses builtins and Bash facilities over external utilities)
+- Clean Bash code (heavily favors builtins and Bash facilities over external utilities)
 
-## Use Cases
+## Preview (v0.2.0)
 
-- Different projects that use $language have different version requirements
-- Performance testing
-- Rootless installations

 ## Current Support
 
-Woof plans to support many tens of languages. Currently, there is limited support for NodeJS, Deno, Go, Crystal, Nim, Dart, and the Hashicorp suite of tools. See the full list in [roadmap](./docs/roadmap.md). Furthermore, the following platforms are supported
-
-- Linux (later Darwin, FreeBSD)
-- amd64 (later x86, armv7l, aarch64)
-- Bash (later Zsh, Ksh, Fish, etc.)
+Woof already supports 10 languages on `x86_64`. For more details, see the [roadmap](./docs/roadmap.md)
 
 We attempt to be reasonably compatible with all existing tools. For example, it will read asdf's [.tool-versions](https://asdf-vm.com/manage/configuration.html#tool-versions), nvm's [.nvmrc](https://github.com/nvm-sh/nvm#nvmrc) and read things from popular version managers like `rvm` and `pyenv`
