System text is formatted as HTML.  To apply formatting to text, words or sentences must be enclosed by 'tags', which are text values enclosed by a starting tag in diagonal brackets ('<example>') and an ending tag with a forward slash ('</example>. 

The most commonly used elements are <p> and </p> to begin and end a paragraph, <b> and </b> to make text bold, and <i> and </i> to italicise text.  Further information can be found at https://www.w3schools.com/html

Additionally, when fields from the database are referenced within the standard text, they are enclosed by curly brackets (e.g. {PROGRAMME}).
