+## Select Command
+Selects a subset of the JSON that is given as input. Uses
+[selection syntax](#selection-syntax) for patterns.
+
+Options:
+ - `--pattern <pattern>`, `-p <pattern>`: Selects using *<pattern>*. If no
+   pattern is specified, the entire JSON object is selected.
+
 ## Verify Command
 Ensures that its input is valid JSON (conformant to the official specification).
 Returns with a zero exit code and prints "Valid JSON" to output if the JSON
 is valid.
 Returns with a non-zero exit code and prints an error to stderr if the JSON
 is not valid.
+
+## Selection Syntax
+To select part of a JSON object, you can use dot-separated parts. Each part
+can be a double-quoted property name, a non-quoted property name, or an
+asterisk, which matches all property names.
+
+For example, the syntax `my_property."a.key".0"` would select an object's
+`my_property` property, then the `a.key` property of that object, and finally
+the first element of that array.
