 ## How to use it
 
-Select a texture, set the [options](#options) accondingly and hit _Create_. It will create a _Material_ and a _Font Settings_ asset with the same name as the texture and in the same folder.
+Select a texture, change the [settings](#settings) accondingly and hit _Create_. It will create a _Material_ and a _Font Settings_ asset with the same name as the texture and in the same folder.
 
 Make sure your texture has the _Read/Write_ enabled inside its properties.
 
 Because of some [limitation](#limitations), it'll not set the _Line Spacing_ field. If you need support to multi-line text, set it on the generated Font Settings file.
 
-## Options
+## Settings
 
-Options are for the project and saved inside the folder _Assets/Editor/Resources_.
+Settings can be saved to [profiles](#profiles) and retrieved to be used later.
 
--  **Texture**: Texture used for the font.
+-  **Texture**: Texture used for the font. This is not saved to the profile.
 -  **Orientation**: Order to look up for characters in the texture. Values: horizontal, vertical.
 -  **Cols**: Number of columns in the texture.
 -  **Rows**: Number of rows in the texture.
 -  **Alpha Threshold**: Alpha threshold to identify characters bounds.
 -  **Monospaced**: Whether the result font should be monospaced.
--  **Character Set**: Predefined character set to use.
+-  **Character Set**: Predefined character set to use. This is not saved to the profile.
 -  **Characters**: Characters used in the font in order they appear in the texture. Use the space character to represent blank spaces in the texture.
 -  **Default Character Spacing**: Default spacing between characters.
 -  **Custom Character Properties**: Custom properties for each characters, if any. For now the only custom property is the spacing.
--  **Profile**: Manage profiles. You can select, create, edit or delete profiles. Same as layout profiles in Unity.
 
 ## Preferences
 
-Preferences are for the editor and saved inside the _EditorPrefs_.
+Preferences are saved in the editor using _EditorPrefs_.
 
 -  **Warn before overwrite**. Warn before overwriting an existing font. This will replace the old font keeping the references.
 -  **Warn before replacing settings**. Warn before replacing settings when selecting a profile.
+-  **Warn before replacing profile**. Warn before replacing an existing profile.
+
+## Buttons
+
+-  **Create**. Creates the font using the given settings.
+-  **Rollback**. Rollback settings to the selected profile or default if none is selected.
+
+## Profiles
+
+You can save profiles to retrieve them later, making easy to create patterns depending on the type of texture or font you are creating.
+
+Profiles are saved to the each project inside the folder _Assets/Editor/Resources_.
+
+All [settings](#settings) except for the _Texture_ and the _Character Set_ can be saved to the profile.
+
+You can manage profiles by opening the _Profiles_ menu at the bottom left corner of the popup. Select, create, edit or delete profiles like you do with layout profiles in Unity.
 
 ## Limitations
 
-This tool makes the most of the work to create a bitmap font to be used with the Text component but it has some limitations:
+This tool makes the most of the work to create a bitmap font to be used with Text components but it has some limitations:
 
 -  **It works only with font sprite sheets not sprite atlases**. It means that the distance between characters in the texture are the same and there is a fixed value of rows and columns. In other words, it has to be a grid of characters. They can't be sparsed.
 -  **It can't set the line specing property**. For some reason, Unity doesn't allow us to edit the _line spacing_ field by code. You need to set it manually after running the tool.
+-  **The resultant font works only with Legacy Text Component**. It doens't work with TextMeshPro texts.
