 ## Install

 ## Usage
+
+On standard in:
+
+```shellsession
+$ echo 'code();' | ast-grep 'code'
+code();
+$ ast-grep 'foo()' < file.js
+foo();
+```
+
+On a set of files:

+
+## Flags
+
+### `--anonymous`
+
+**Alias**: `-a`
+
+Ignore names, this includes identifiers, types, etc.
+
+## Examples
+
+### Find all no-arg function calls:
+
+```shellsession
+$ echo -e 'foo();\nbar();' | ast-grep 'fn()' -a
+foo();
+bar();
+```

+## FAQ
+
+### Q. But @azz, `grep` stands for Global Regular Expression Print, this tool doesn't use Regular Expressions!
+
+**A.** I know, but `gastp` doesn't sound great.

Trivial Package

Supply chain risk

Packages less than 10 lines of code are easily copied into your own project and may not warrant the additional supply chain risk of an external dependency.
