+commands.json
+=============
+
+:code:`commands.json` files define how subcommands are executed by the
+:code:`./wpt` command. :code:`wpt` searches all command.json files under the top
+directory and sets up subcommands from these JSON files. A typical commands.json
+would look like the following::
+
+  {
+    "foo": {
+      "path": "foo.py",
+      "script": "run",
+      "parser": "get_parser",
+      "help": "Run foo"
+    },
+    "bar": {
+      "path": "bar.py",
+      "script": "run",
+      "virtualenv": true,
+      "requirements": [
+        "requirements.txt"
+      ]
+    }
+  }
+
+Each key of the top level object defines a name of a subcommand, and its value
+(a properties object) specifies how the subcommand is executed. Each properties
+object must contain :code:`path` and :code:`script` fields and may contain
+additional fields. All paths are relative to the commands.json.
+
+:code:`path`
+  The path to a Python script that implements the subcommand.
+
+:code:`script`
+  The name of a function that is used as the entry point of the subcommand.
+
+:code:`parser`
+  The name of a function that creates an argparse parser for the subcommand.
+
+:code:`parse_known`
+  When True, `parse_known_args() <https://docs.python.org/3/library/argparse.html#argparse.ArgumentParser.parse_known_args>`_
+  is used instead of parse_args() for the subcommand. Default to False.
+
+:code:`help`
+  Brief description of the subcommand.
+
+:code:`virtualenv`
+  When True, the subcommand is executed with a virtualenv environment. Default
+  to True.
+
+:code:`requirements`
+  A list of paths where each path specifies a requirements.txt. All requirements
+  listed in these files are installed into the virtualenv environment before
+  running the subcommand. :code:`virtualenv` must be true when this field is
+  set.
+
+:code:`conditional_requirements`
+  A key-value object. Each key represents a condition, and value represents
+  additional requirements when the condition is met. The requirements have the
+  same format as :code:`requirements`. Currently "commandline_flag" is the only
+  supported key. "commandline_flag" is used to specify requirements needed for a
+  certain command line flag of the subcommand. For example, given the following
+  commands.json::
+
+    "baz": {
+      "path": "baz.py",
+      "script": "run",
+      "virtualenv": true,
+      "conditional_requirements": {
+        "commandline_flag": {
+          "enable_feature1": [
+            "requirements_feature1.txt"
+          ]
+        }
+      }
+    }
+
+  Requirements in :code:`requirements_features1.txt` are installed only when
+  :code:`--enable-feature1` is specified to :code:`./wpt baz`.
