 This is a tool to find calls at javascript code.
 
+### Installation
+
+```
+npm install -g jscode-find-callee
+```
+
 ### Usage
 The following example will search for all `console` calls at the `fixtures/console_log_2.js` sourcecode.
 ```
-node bin/jscode-find-callee fixtures/console_log_2.js
+jscode-find-callee fixtures/console_log_2.js
 ```
 
 If you want to search for an other callee instead of `console` you can use the `--name` flag.
 ```
-node bin/jscode-find-callee --name logger fixtures/console_log_2.js
+jscode-find-callee --name logger fixtures/console_log_2.js
 ```
 
 It is also possible to search an entire directory.
 ```
-node bin/jscode-find-callee --name console fixtures
+jscode-find-callee --name console fixtures
 ```
