Simply add {{WikiProject Software}} to an article's talk page at or near the top (generally, below any that are more specific, and any that relate to current AfD or similar issues, and any that relate to article milestones, such as Good Article status; but above less specific ones, such as projects relating to technology, computers, etc., more generally).

{{WikiProject Software
|class                = 
|importance           = 
|computing-importance = 
|attention            = <!-- Yes/No -->
|needs-infobox        = <!-- Yes/No -->
|needs-image          = <!-- Yes/No -->
}}

• attention – set |attention=yes if the article needs immediate attention from experienced editors. Use only if another parameter does not cover the need for attention; this should be used sparingly. It is strongly encouraged to also add a section to the talk page explaining what needs attention.
  • This parameter populates Category:Software articles needing attention.
• class – valid values are listed in the custom class mask. See the project's quality scale for details. Setting an explicit value of NA is rarely necessary; for this, either leave |class= blank or omit the parameter.
• computing-importance – see the importance scale of WikiProject Computing for details.
• importance – valid values are: top, high, mid, low, na (case-insensitive). See the project's importance scale for details. Setting an explicit value of NA is rarely necessary; for this, either leave |importance= blank or omit the parameter.
• listas – This parameter, which is the equivalent of the DEFAULTSORT sortkey that should be placed on all biographical articles, is a sortkey for the article talk page (e.g. for Ada Lovelace, use |listas=Lovelace, Ada so that the talk page will show up in the L's and not the A's of the various assessment and administrative categories). This is important because it is one source used by those who set DEFAULTSORT on the article; consider also setting the DEFAULTSORT for the article when setting this parameter. For more information about this, please see Wikipedia:Categorization of people § Ordering names in a category.
  If the article is using {{WikiProject banner shell}} then it is preferable to add |listas= to that template instead of a project banner template. Putting the parameter on more than one template is not required.
• needs-image – set |needs-image=yes if the article needs an image.
  • This parameter populates Category:Software articles needing images.
• needs-infobox – set |needs-infobox=yes if the article needs an infobox. Remember that infoboxes are not suitable for all articles, and can overwhelm short articles.
  • This parameter populates Category:Software articles without infoboxes.
• auto – This parameter is for the use of bots and indicates that the article has been automatically rated:
  • |auto=length – based on the length of the article
  • |auto=inherit – because one or more other projects use this class
  • |auto=yes (or |auto=stub), in conjunction with |class=stub – as Stub-Class because it uses a stub template
    • Use of the above values (or value combinations) with this parameter populates Category:Automatically assessed software articles.
• category – set |category=no if, and only if, a banner is being used for demonstration or testing purposes, to prevent unnecessary or undesirable categorization. Otherwise, omit this parameter.

• The parameter |importance-comp= is recognised as an alias for |computing-importance=. If both |computing-importance= and |importance-comp= are present, |importance-comp= is ignored.
