+## Uninstalling Rustlings
+
+If you want to remove Rustlings from your system, there's two steps. First, you'll need to remove the exercises folder that the install script created
+for you:
+
+``` bash
+rm -rf rustlings # or your custom folder name, if you chose and or renamed it
+```
+
+Second, since Rustlings got installed via `cargo install`, it's only reasonable to assume that you can also remove it using Cargo, and
+exactly that is the case. Run `cargo uninstall` to remove the `rustlings` binary:
+
+``` bash
+cargo uninstall rustlings
+```
+
+Now you should be done!

 ## Completion
 
 Rustlings isn't done; there are a couple of sections that are very experimental and don't have proper documentation. These include:

 Thanks for installing Rustlings!
 
-Is this your first time?
+Is this your first time? Don't worry, Rustlings was made for beginners! We are
+going to teach you a lot of things about Rust, but before we can get
+started, here's a couple of notes about how Rustlings operates:
 
-Let's make sure you're up to speed:
+1. The central concept behind Rustlings is that you solve exercises. These
-- You have Rust installed, preferably via `rustup`
+   exercises usually have some sort of syntax error in them, which will cause
-- You have `~/.cargo/bin` added to your PATH variable
+   them to fail compilation or testing. Sometimes there's a logic error instead
-- You have cloned this repository (https://github.com/rust-lang/rustlings)
+   of a syntax error. No matter what error, it's your job to find it and fix it!
-- You have installed Rust language support for your editor
+   You'll know when you fixed it because then, the exercise will compile and
-- You have locally installed the `rustlings` command by running an
+   Rustlings will be able to move on to the next exercise.
-  installation script or manually executing:
+2. If you run Rustlings in watch mode (which we recommend), it'll automatically
+   start with the first exercise. Don't get confused by an error message popping
+   up as soon as you run Rustlings! This is part of the exercise that you're
+   supposed to solve, so open the exercise file in an editor and start your
+   detective work!
+3. If you're stuck on an exercise, there is a helpful hint you can view by typing
+   'hint' (in watch mode), or running `rustlings hint myexercise`.
+4. If an exercise doesn't make sense to you, feel free to open an issue on GitHub!
+   (https://github.com/rust-lang/rustlings/issues/new). We look at every issue,
+   and sometimes, other learners do too so you can help each other out!
