 However, before submitting, please review the following:
 
 For bug reports:
+
   - Please make sure the bug is reproducible, and give us the steps to reproduce it, so that we can dig into the problem.
   - Please give us as much detail as possible about your environment, so we can more easily confirm the problem.
 
 For pull requests:
+
   - Please include tests. Changes with tests will be merged very quickly.
   - Please manually confirm that your changes work in `bash`, `sh`/`dash`, `ksh`, and `zsh`. Fast tests do run in these shells, but it's nice to manually verify also.
   - Please maintain consistent whitespace - 2-space indentation, trailing newlines in all files, etc.

 ## Installing nvm on Alpine Linux
+
 In order to provide the best performance (and other optimisations), nvm will download and install pre-compiled binaries for Node (and npm) when you run `nvm install X`. The Node project compiles, tests and hosts/provides pre-these compiled binaries which are built for mainstream/traditional Linux distributions (such as Debian, Ubuntu, CentOS, RedHat et al).
 
 Alpine Linux, unlike mainstream/traditional Linux distributions, is based on [BusyBox](https://www.busybox.net/), a very compact (~5MB) Linux distribution. BusyBox (and thus Alpine Linux) uses a different C/C++ stack to most mainstream/traditional Linux distributions - [musl](https://www.musl-libc.org/). This makes binary programs built for such mainstream/traditional incompatible with Alpine Linux, thus we cannot simply `nvm install X` on Alpine Linux and expect the downloaded binary to run correctly - you'll likely see "...does not exist" errors if you try that.
