The "Site Identity" form
You will find everything in Configuration -> Site Identity.
Note that these important data are used by tags and forms included in the templates for your site; these data relate to the content of your pages and the referencing data included in the HTML pages of your site.
The site name
The first field on the form, labelled "Your site’s name", is used to enter and save that text that will become the site name shown in the title of each of your site’s pages. By default, this will contain "[My SPIP site]": don’t forget to change it and put in your own!
This information is called in the templates with the tag #NOM_SITE_SPIP.
Site slogan
This is the short description of your site / activity. It will be displayed under the logo / title of your site.
The associated tag: #SLOGAN_SITE_SPIP

This field must contain the URL address of your public site.
Tip : leave this field empty and validate the form. The field will be automatically filled in.
The associated tag: #URL_SITE_SPIP
Site description
Enter a few pertinent short phrases that will enable site visitors to quickly understand what your site is all about.
The associated tag: #DESCRIPTIF_SITE_SPIP

Webmaster’s email address
By default, SPIP will use the email address of whoever installed the site (the first administrator).

Logo of the site
Load your site’s logo here.
If you are using the default SPIP templates, this logo is displayed in the banner. This logo is also present elsewhere, in particular in the "backend" file to which Internet users can subscribe. So choose a reasonable size.
