+.. code-block:: console
+
+    Usage:
+      behat [options] [--] [<paths>]
+
+    Arguments:
+      paths
+          Optional path(s) to execute. Could be:
+           - a dir (features/)
+           - a feature (*.feature)
+           - a scenario at specific line (*.feature:10).
+           - all scenarios at or after a specific line
+              (*.feature:10-*).
+           - all scenarios at a line within a specific range
+              (*.feature:10-20).
+           - a scenarios list file (*.scenarios).
+
+    Options:
+      -s, --suite=SUITE
+          Only execute a specific suite.
+      -f, --format=FORMAT
+          How to format tests output. pretty is default.
+          Available formats are:
+          - pretty: Prints the feature as is.
+          - progress: Prints one character per step.
+          - junit: Outputs the failures in JUnit compatible
+          files.
+          You can use multiple formats at the same time.
+          (multiple values allowed)
+      -o, --out=OUT
+          Write format output to a file/directory instead of
+          STDOUT (output_path). You can also provide different
+          outputs to multiple formats. This option is mandatory
+          for the junit formatter. (multiple values allowed)
+      --format-settings=FORMAT-SETTINGS
+          Set formatters parameters using json object.
+          Keys are parameter names, values are values. (multiple
+          values allowed)
+      --init
+          Initialize all registered test suites.
+      --lang=LANG
+          Print output in particular language.
+      --name=NAME
+          Only execute the feature elements which match part
+          of the given name or regex. (multiple values allowed)
+      --tags=TAGS
+          Only execute the features or scenarios with tags
+          matching tag filter expression. (multiple values
+          allowed)
+      --role=ROLE
+          Only execute the features with actor role matching
+          a wildcard.
+      --narrative=NARRATIVE
+          Only execute the features with actor description
+          matching a regex.
+      --story-syntax
+          Print *.feature example.
+          Use --lang to see specific language.
+      -d, --definitions=DEFINITIONS
+          Print all available step definitions:
+          - use --definitions l to just list definition
+          expressions.
+          - use --definitions i to show definitions with extended
+          info.
+          - use --definitions 'needle' to find specific
+          definitions.
+          Use --lang to see definitions in specific language.
+      --snippets-for[=SNIPPETS-FOR]
+          Specifies which context class to generate snippets for.

+      --strict
+          Passes only if all tests are explicitly passing.
+      --order=ORDER
+          Set an order in which to execute the specifications
+          (this will result in slower feedback).
+      --rerun
+          Re-run scenarios that failed during last execution,
+          or run everything if there were no failures.
+      --rerun-only
+          Re-run scenarios that failed during last execution,
+          or exit if there were no failures.
+      --stop-on-failure

+      --colors
+          Force ANSI color in the output. By default color
+          support is guessed based on your platform and the
