+===== Pattern Search Behaviour and how to use 'Regular Expression' in a Search =====
 Regular expressions, often abbreviated as regex or regexp, are powerful tools for pattern matching and text manipulation. They provide a concise and flexible way to describe, search, and manipulate strings.
+==== Adding Every File as it's Own Case ====
+.*
+That's all you need. The '.' matches any character except for a new line, and the '*' says the preceeding character can be matched 0 or more times.\\
+In the screenshot below, you can see this search makes a new case for every WSI file in the directory.
+{{ :pattern search 3.png?600 |}}
+Here are some examples of how .* behaves in a regex pattern:
+abc.*def: This pattern would match strings that start with "abc" and are followed by any sequence of characters, eventually ending with "def". For example, it would match "abc123def" or "abcxyzdef".
+.*\d+.*: This pattern would match strings that contain one or more digits anywhere in the string. The .* before and after \d+ allows for any characters before and after the digit(s).
+In the screenshot below you can see that '.*-' matches only files that have a '-' in their name
+{{ :pattern search 5.png?600 |}}
+==== Adding Similarly Named Files into Cases ====
+What about if you have file(s) named in a similar way?
+We can use some simple commands to sort these into cases.
+Here you can see that typing '.' matches all files starting with the same character into a Case.
+{{ :pattern search 4.png?600 |}}
+If you have files with different names, but each case shares the first 4 letters or numbers, you can type '....' to group them together.
+Another way to search and group together files into Cases is using [].\\
+Any search terms you put within the [] will be searched for.\\
+In the example below, we use ^[\d\w]* to find the starting pattern of each filename until it is interrupted by a special character e.g. '(' or '.'
+{{ :pattern search 6.png?600 |}}
+You can also chain several of these blocks together, for example:\\
+^[\d\w]+-[\d\w]+-[\d\w] would find all files with three strings of alphanumeric characters, each separated by a '-'
+==== Finding Many Files for a Single Case ====
+You can use pattern search like a regular search engine to find 'files' in your selected folder\\

 Using ? to indicate subexpressions in your pattern, e.g. "fish(er)?" matches "fish" or "fisher".

+==== Full Explanation of Regular Expression Syntax ====
 Here are some key concepts and syntax:
 . Literal Characters:\\
 Most characters in a regular expression match themselves literally. \\
 For example, the regular expression abc will match the string "abc" in the input.
