If you are running NodeBB via git, it is also helpful to let the maintainers know what commit hash you are on. To find the commit hash, execute the following command:

``` bash
$ cd /path/to/my/nodebb
$ git rev-parse HEAD
```

If you have downloaded the `.zip` or `.tar.gz` packages from GitHub (or elsewhere), please let us know.

## Attempt to use `git bisect`

If you have installed NodeBB via GitHub clone, are familiar with utilising git, and are willing to help us narrow down the specific commit that causes a bug, consider running `git bisect`.
