1) Put the numbre of posts you want to display before pagination in “The maximum number of posts to display in this list” box

2) Define the tags you want to display so that people can display the next or previous page in the list. This goes in the “Navigation next-link” and “Navigation prev-link” fields.
I used:

<a href="%ple_navigation_next_url%">Next page-->></a>

<a href="%ple_navigation_prev_url%"><<--Previous page</a>

3) The tags you defined in 2) are now held in two variables:
%ple_navigation_prev_link% and
%ple_navigation_next_link%

You now insert %ple_navigation_prev_link% in the “This html code will be displayed after the last entry” field.

%ple_navigation_next_link% goes in the “This html code will be displayed before the first entry”

Answer: Thank you very much, for these english instructions!
