f Drupal 5:

INSTALLATION:

Step 0)
  Have a working installation of Drupal.  See http://drupal.org/project/drupal

Step 1)
  Copy the 'edit_term.module', 'edit_term.install', and
'edit_term.info' files within their 'taxonomy_install' subdirectory 
into your 'modules', 'sites/all/modules', or site-specific modules directory.
  Drupal ninjas can automate installation with http://drupal.org/project/drush

Step 2)
  Enable the edit_term module.  

  Go to "Administer >> Build >> Modules" and put a checkmark in the 'status' 
column next to 'edit_term'.  Drupal will automatically create the 
necessary database tables when you submit this form.

  Configure the edit_term module.

  Go to "Administer >> Settings >> Edit term" to configure the module.

Step 4)
  Enable the edit term block (or blocks).
