 ## Checks
-There are 11 predfined checks each representing a password criteria. 
+There are 11 predfined checks each representing a password criteria. Each check type is defined as a bit flag. A combination of checks can thus be simply refrenced using a single integer. All predefined check types are defined [here.](source/EzPasswordValidator/Checks/CheckTypes.cs)
 
-##### Length check 
-Checks if the given password is equal to or longer than the required minimum length.
+#### Length check 
+Checks if the given password is equal to or longer than the required minimum length
+and equal to or shorter than the maximum allowed length.     
+```
+Default minimum length: 8     
+Default maximum length: 128
+```
+
+Changing length bounds example:
+
+```C#
+validator.MinLength = 10;
+validator.MaxLength = 256;
 
-##### Check for numbers
+//OR
+
+validator.SetLengthBounds(10, 256);

+
+#### Check for numbers
 Checks that the password contains at least one digit.
 
-##### Check for letters
-Checks that the password contains at least one letter.
+#### Check for letters
+Checks that the password contains at least one letter. This check supports multiple alphabets. For more information about how we classify a letter see [this](https://docs.microsoft.com/en-us/dotnet/api/system.char.isletter?view=netframework-4.8#remarks) refrence.
 
-##### Check for symbols
+#### Check for symbols
 Checks that the password contains at least one symbol.
 
-##### Case check
-Checks that the password contains at least one upper- and lower-case letter.

-##### Check for number sequences
-Checks if the password contains a number series 3 or longer such as 123 or 765.
+#### Check for number sequences
+Checks if the password contains a number series 3 or longer. Both increasing sequences and decreasing sequences are checked.    
+```
+Example number sequence: 123  |  765
+```
 
-##### Check for number repetition
-Checks if the password contains number repetition 3 or longer in length, such as 444 or 222.
+#### Check for number repetition
+Checks if the password contains number repetition 3 or longer in length.
+```
+Example number repetition: 444  |  222

-##### Check for number location 
-Checks that the password does not only have numbers in the front and/or end of the password.
+#### Check for number location 
+Checks that the password does not only have numbers in the front and/or end of the password. To pass this check the password must have a non-digit character before and after a digit character, only one digit must match this pattern.
+```
+Example invalid password: 2password   |  password2
+Example valid   password: 2pass9word  |  p6ssword
+```
 
-##### Check for letter sequences
+#### Check for letter sequences
 Checks if the password contains an alphabetical letter sequence consisting of four or more
-characters. With the exception of the common three letter sequences: abc and xyz.

+Note: this check currently only supports ISO basic latin alphabet (A-Z a-z).

-##### Check for letter repetition
+#### Check for letter repetition
 Checks if the password contains letter repetition 3 or longer in length.
-The check is not case sensitive meaning 'aAA' and 'aaa' will both match.

-##### Check for symbol repetition
+#### Check for symbol repetition
 Checks for immediate symbol repetition 3 or longer in sequence.
+```
+Example symbol repetiton: ///  |  @@@
