+# Unrestrict Where ripgrep Searches
+
+One of the conveniences of [`rg`
+(ripgrep)](https://github.com/BurntSushi/ripgrep) is that by default it doesn't
+search in places you probably don't want it to search. That means it ignores
+anything specified by your `.gitignore` file, it excludes hidden files and
+directories (dotfiles, e.g. `.git/` or `.env`), and it excludes binary files.
+
+These restrictions can be incrementally undone as needed using the `-u` flag.
+
+The `-u` flag on its own will remove the ignored files restriction. This is
+equivalent to the `--no-ignore` flag.
+
+```bash
+$ rg -u pattern
+```
+
+Adding an additional `u` (`-uu`) to that flag will remove both the ignored files and
+hidden files restrictions. This is a shorthand equivalent to both `--no-ignore`
+and `--hidden`.
+
+```bash
+$ rg -uu pattern
+```
+
+Adding one more `u` (`-uuu`) will additionally remove the binary file
+restriction. Equivalent to those other two flags plus `--text`.
+
+```bash
+$ rg -uuu pattern
+```
