How to Show full content and Add "Read more "?

Hi there,

Does anyone know how to (1)Show full content OR Clear the excerpt setting on home page and categories, tags, etc.,

can only change it to longer content…

(2) and, Add “Read more ” ?

Tried to do:

Found this in content.php file in the root of esplanade folder:

<div class=”entry-summary”>
<?php the_excerpt(); ?>
</div><!– .entry-summary –>

Replace with this:

<div class=”entry-summary”>
<?php the_excerpt(); ?>” rel=”bookmark” title=”<?php the_title_attribute(); ?>”>Read More
</div><!– .entry-summary –>

It showed:

” rel=”bookmark” title=””>Read More
instead of
Read kmore

I’m very new in wordpress and coding stuffs.
After whole day reading the articles, still can’t figure out how to fix the problems
