-## Usage
+## Usage examples
 
-TODO
+You can either parse variables inside strings or even directly in files.
 
-### Examples
+### Basic
 
-#### Basic
-
 ```ruby
     url = "https://my-domain.com/items/{{item_id}}"
     final_url = CurlyBracketParser.parse url, item_id: 123
     # => "https://my-domain.com/items/123"
 ```
 
-#### Filters
+### Filters
 
 ```ruby
     url = "https://my-domain.com/catalog/{{item_name|snake_case}}"
     final_url = CurlyBracketParser.parse url, item_name: 'MegaSuperItem'
     # => "https://my-domain.com/catalog/mega_super_item"
 ```
 
-#### Globals
+For a list of built-in filters visit [LuckyCase](https://github.com/magynhard/lucky_case).
 
-TODO
+#### Define your custom filter
+
+```ruby
+    CurlyBracketParser.register_filter('7times') do |string|
+      string.to_s * 7
+    end
+
+    text = "Paul went out and screamed: A{{scream|7times}}h"
+    final_text = CurlyBracketParser.parse text, scream: 'a'
+    # => "Paul went out and screamed: Aaaaaaaah"
+```
+
+### Files
+
+<ins>test.html</ins>
+```html
+<h1>{{title|sentence_case}}</h1>
+```
+
+```ruby
+    parsed_file = CurlyBracketParser.parse_file './test.html', title: 'WelcomeAtHome'
+    # => "<h1>Welcome at home</h1>"
+```
+
+Use `#parse_file!` instead to write the parsed string directly into the file!
+
+### Default variables
+
+You can define default variables, which will be replaced automatically without passing them by parameters, but can be overwritten with parameters.
+
+Because of providing blocks, your variables can dynamically depend on other states.
+
+```ruby
+    CurlyBracketParser.register_default_var('version') do
+      '1.0.2'
+    end
+
+    text = "You are running version {{version}}"
+    CurlyBracketParser.parse text
+    # => "You are running version 1.0.2"
+    CurlyBracketParser.parse text, version: '0.7.0'
+    # => "You are running version 0.7.0"
+```
