===Coding===
In wiki code, it is recommended to add references by within <nowiki><ref> and </ref></nowiki> tags, in addition to adding the {{tl|reflistTop}} at the bottom of the articleand {{tl|Bottom}} templates to their respective places. Such <nowiki><ref></nowiki> tags can be automatically generated from the doi codes, PMID or PMCID of articles at this site:
*[http://sumsearch.org/cite/ http://sumsearch.org/cite/]
For example, entering 10.1038/438900a at that page yields the following text:
When inserted in an article, it gives the following at the bottom:
*{{cite journal| author=Giles J| title=Internet encyclopaedias go head to head. | journal=Nature | year= 2005 | volume= 438 | issue= 7070 | pages= 900-1 | pmid=16355180 | doi=10.1038/438900a | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=16355180 }}
===Notes===
Notes are added by adding ''group='' to the ref tag, such as:
*<nowiki><ref name="pitch" group="notes">Detailed explanations and references are located in the [[Calcaneal pitch]] article.</ref></nowiki> as seen in the article [[X-ray of flat feet]]
