 First we'll start with the Atom package system. As we mentioned previously, Atom itself is a very basic core of functionality that ships with a number of useful packages that add new features like the [Tree View](https://github.com/atom/tree-view) and the [Settings View](https://github.com/atom/settings-view).
 
-In fact, there are more than 90 packages that comprise all of the functionality that is available in Atom by default. For example, the [Welcome screen](https://github.com/atom/welcome) that you see when you first start Atom, the [spell checker](https://github.com/atom/spell-check), the [themes](https://github.com/atom/one-dark-ui) and the [Fuzzy Finder](https://github.com/atom/fuzzy-finder) are all packages that are separately maintained and all use the same APIs that you have access to, as we'll see in great detail in [Hacking Atom](/hacking-atom/).

 This means that packages can be incredibly powerful and can change everything from the very look and feel of the entire interface to the basic operation of even core functionality.

One of these may be that multiple user accounts on a machine want to use the same Atom Home. The environment variable used to specify and alternate location is called `ATOM_HOME`.

-You can limit a search to a subset of the files in your project by entering a [glob pattern](https://en.wikipedia.org/wiki/Glob_%28programming%29) into the "File/Directory pattern" text box. For example, the pattern `src/*.js` would restrict the search to javascript files in the `src` directory. The "globstar" pattern (`**`) can be used to match arbitrarily many subdirectories. For example, `docs/**/*.md` will match `docs/a/foo.md`, `docs/a/b/foo.md`, etc. You can enter multiple glob patterns separated by commas, which is useful for searching in multiple file types or subdirectories.

 When you have multiple project folders open, this feature can also be used to search in only one of those folders. For example, if you had the folders `/path1/folder1` and `/path2/folder2` open, you could enter a pattern starting with `folder1` to search only in the first folder.
