 # file-header
-A template based commandline file-header generator
+A CLI tool for generating file header from a configuration file and an EJS template.
+
+
+## Installation 
+
+#### install the package
+`npm i -g file-header`
+
+#### Edit the config file ( Optional )
+Data to be presented on a file header is stored in a config file which is located at `~/.file-headers/template_data.js`
+
+The default content of this file will be as follows.
+```javascript
+module.exports = {
+  user: process.env.USER,
+  email: process.env.USER + '@' + process.env.HOST,
+  date: new Date(),
+};
+
+```
+
+We can customize it as required. For example, change it to
+
+```javascript
+module.exports = {
+  user: 'Jake sully'
+  email: 'gmail@jakesully.com'
+  github: 'https://github.com/jakesully'
+  date: new Date(),
+};
+```
+
+#### Edit the [EJS](ejs) tempalte of the default file-header ( Optional )
+
+The default file header template can be found at `~/.file-headers/default`
+It is just [EJS](ejs) template. We can customize it to any extend.
+
+If we require different template for each file type , create a file  `~/.file-headers/<extention>`
+
+For javscript, create a custom template at  `~/.file-headers/js` and customize it.
+
+
+## Usage
+
+Commandline
+```
+file-header <filename.ext>
+```
+which will print the file header to your console.
+
+
+#### Use with Vim editor
+
+Add the below line to your vim config file
+```vim
+command! Header :execute '0r!file-header %'
+```
+
+Now, type `:Header` to add file header to your current buffer.
