Foreword

This quick tutorial shows you all necessary steps to create a custom **HumHub** theme.

- Step 1: Create a theme folder ([Theme Folder Structure](structure.md))
- Step 2: Adjust colors and build CSS ([Custom Stylesheets](css.md))
- Step 3: Modify login template ([View Files](views.md))


Step 1: Create an own theme folder
---------------------------------
- Go to the HumHub installation directory
- Switch to the directory `themes`
- Copy the folder `HumHub` and rename it to `Example`
- Enable the new `Example` theme under `Administration -> Settings -> Appearance`

Step 2: Adjust colors and build CSS 
-----------------------------------

### Installing prerequisites 

**Install NodeJS** 

See: https://nodejs.org/en/download/

**Install LESS**

Open the command console and execute:

```
npm -g install less
```

### Modify theme colors
Add modifed color variables to the file `/themes/Example/less/variables.less`.

```
@default: #ededed;
@primary: #A66F00;
@info: #FFAA00;
@success: #97d271;
@warning: #fdd198;
@danger: #FFD073;
```

### Compile LESS file
Open the command console and change to the themes `less` directory

``` 
cd /path/to/HumHub/themes/Example/less
```

Build the CSS package

Step 3: Modify login template
------------------------------

In this step we're adding some text to the login template.

### Create a themed view file
Copy the view file `humhub/modules/user/views/auth/login.php` to `Example/views/user/auth/login.php`

### Modify the view file
Add some additional text below the application name.

```php
<span style="width:100px; color:white;">
    Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.<br />
