CKEditor

There are two parts to installing CKEditor for Drupal 7 (Drupal 8 comes with it already installed):

1. The CKEditor Drupal module, which is placed in the sites/all/modules folder.
2. The CKEditor library, which is placed INSIDE the sites/all/libraries folder.

After installing the module and library, enable the module and it should take effect immediately.

The Drupal community on campus has found a number of modules which help with using CKEditor:

IMCE

Versions: Drupal 10, 7

​IMCE can be used for managing images, and you might even use imce for files, as well.

Installation instructions for IMCE:

A "rich text" or "WYSIWYG" (What You See is What You Get) text editor gives your content editors a way to create and maintain content using an interface that looks and feels a lot like using a word processor.  Formatting is applied using button controls, so the content editor doesn't have to know anything about HTML and can immediately see what the content is going to look like after it has been saved.
