+# Find Files With fd
+
+The [`fd` command](https://github.com/sharkdp/fd) is an open-source utility
+written in Rust. It is a fast and user-friendly way to find files -- as
+compared to the standard `find` command.
+
+You can recursively look in the current directory for a file with `git` in
+the name like so:
+
+```bash
+$ fd git
+```
+
+If you have a `.gitignore` file, it will ignore those files and directories
+by default.
+
+Providing a second argument, `fd` will start its recursive search from that
+directory.
+
+```bash
+$ fd git ~
+```
+
+Here, `fd` will look for filenames with `git` everywhere within my home
+directory.
+
+You can `brew install fd` to get the command and `man fd` for more details.
