 ## Features
-- Single file, easy installation :sparkles:
-- Fast fast fast fast :rocket:
-- Install multiple node versions without a hassle! :clap:
-- [Project-specific `.nvmrc` file support](./features_tests/nvmrc)
+:sparkles: Single file, easy installation
+
+:rocket: Built with speed in mind
+
+:thinking: Works with `.nvmrc` files
 
 ## Installation
 
-* Download the [latest release binary](https://github.com/Schniz/nsw/releases) for your system
+* Download the [latest release binary](https://github.com/Schniz/fnm/releases) for your system
 * Make it available globally on `$PATH`
 * Add the following line to your `.bashrc`/`.zshrc` file:
 
   ```bash
-  eval `nsw env`
+  eval `fnm env`
   ```
 
-## TODO
+## Future Plans
+- [ ] Add a simpler way of installing it (`curl | bash`?)
 - [ ] Feature: make versions complete the latest: `10` would infer the latest minor and patch versions of node 10. `10.1` would infer the latest patch version of node 10.1
-- [ ] Feature: `nsw use --install`, `nsw use --quiet`
-- [ ] Feature: `nsw install lts`?
-- [ ] Feature: `nsw alias`?
+- [ ] Feature: `fnm use --install`, `fnm use --quiet`
+- [ ] Feature: `fnm install lts`?
+- [ ] Feature: `fnm alias`?
 - [ ] Feature: Consider nvm-like per-shell usage with symlinks on `/tmp` directory
 - [ ] OSX: Add to homebrew?
 - [ ] Windows Support?
 - [ ] Linux: Replace `curl` usage with `cohttp`/`ocurl` or something else which is statically-linkable
 - [ ] Linux: Replace `tar` with a statically linked library too (for ungzip + untar)
