Add article title to read more link

For this you can use the overrides...

If they are not already there, in your template folder: create a new folder called 'html'.
In that folder you create a folder called 'com_content'.
And in that folder you create the folders called "category", "homepage", "section"

Then locate the following files

(joomla)/components/com_content/views/category/tmpl/blog_item.php

(joomla)/components/com_content/views/homepage/tmpl/default_item.php

(joomla)/components/com_content/views/section/tmpl/blog_item.php

Copy the files to your template's html folders

(yourtemplate)/html/com_content/category/blog_item.php

(yourtemplate)/html/com_content/frontpage/default_item.php

(yourtemplate)/html/com_content/section/blog_item.php

Open these files.

 
Nearly at the bottom of these files you should be seeing something like:

<a href="<?php echo $this->item->readmore_link; ?>"

class="readon<?php echo $this->item->params->get('pageclass_sfx'); ?>">

     <?php if ($this->item->readmore_register) :

          echo JText::_('Register to read more...');

     elseif ($readmore = $this->item->params->get('readmore')) :

          echo $readmore;

     else :

          echo JText::sprintf('Read more...');

     endif; ?></a>

Change the line

echo JText::sprintf('Read more...');

into

echo JText::sprintf('Read more', $this->item->title);

The “Read more” link should now look like this: Read more: (Article title)
