-### Assignment Requirements
+## Assignment Requirements
 
 Please follow [these instructions][cli-walkthrough] to download the Exercism CLI for your OS.
 
 Once the CLI is set up and configured, download the first exercise - `hello-world`:
 
-```bash
-$ exercism download --exercise=hello-world --track=javascript
+```shell
+exercism download --exercise=hello-world --track=javascript
 ```
 
 Each assignment then needs some tools to run the tests.
 They can be installed running this command within each assignment directory:
 
-```bash
-$ npm install
+```shell
+npm install
 ```
 
+> _**Help**_: `'<package>' is missing / cannot be found`
+>
+> If you see this after _upgrading_ your exercise, welcome to npm 7.
+> Delete `node_modules` and `package-lock.json` and re-run the command to resolve this.
+
 If you're concerned about disk space and are okay installing another tool, take a look at [pnpm](https://pnpm.io/), which ensure only one copy of each package-version is ever installed on disk.
 In this case, run `pnpm install` instead of `npm install`, and everything should work as expected.

 Execute the tests with:

 Be sure your code follows best practices and coding styles, as other users do, with ESLint, a tool to perform static analysis on your code.
 Sometimes, tools like this save you some time detecting typos or silly mistakes in your JavaScript code:
 
-```bash
-$ npm run lint
+```shell
+npm run lint
 ```
 
 You can also run Jest in "watch" mode, which will re-run your tests automatically when you save changes to the code or test module:
 
-```bash
-$ npm run watch
+```shell
+npm run watch
 ```
