remove README information that is provided by the command

Running query.sh without any arugments already provides usage
information that is sometimes more details than the README. We should
just pick one place for documentation and leave the other empty. The
query scripts are automatically read for documentation, so they're more
likely to be up-to-date than the README.

-# JSON module graph queries
+JSON module graph queries
+=========================
 
 This directory contains `jq` scripts that query Soong's module graph.
 `jq` may be installed through your distribution's repository.
 
-Usage:
-
-```
-m json-module-graph
-query.sh [-C] <command> <base-of-your-tree>/out/soong/module-graph.json [argument]
-```
-
-The following commands are available:
-* `directDeps` prints the names of the direct dependencies of the given module
-* `distanceFromLeaves` prints the longest distance each module has from a leaf
-  in the module graph within the transitive closure of given module
-* `filterSubtree` dumps only those modules that are in the given subtree of the
-  source tree
-* `fullTransitiveDeps` returns the full transitive dependencies of the given
-  module
-* `moduleTypeStats`: returns of a summary of the module types present on the
-  input
-* `modulesOfType`: returns the names of modules of the input type
-* `printModule` prints all variations of a given module
-* `printModule`: returns a slightly more consise view of the input module
-* `properties`: returns the properties set in the input module, includes
-  properties set via defaults
-* `transitiveDeps` prints the names of the transitive dependencies of the given
-  module. $arg can be comma-separated module names
-* `usedVariations` returns a map that shows which variations are used in the
-  input and what values they take
-* `variantTransitions`  summarizes the variant transitions in the transitive
-  closure of the given module
-* `fullTransitiveDepsProperties` returns the properties set (including via
-  defaults) grouped by module type of the modules in the transitive closure of
-  the given module
-
 It's best to filter the full module graph to the part you are interested in
 because `jq` isn't too fast on the full graph.
 
-To query about a module's inputs/outputs or actions:
+Usage
+-----
 
 ```
 m json-module-graph
-query.sh [-C] <command> <base-of-your-tree>/our/soong/module-actions.json [argument]
+query.sh [-C] <command> <base-of-your-tree>/out/soong/module-graph.json [argument]
 ```
 
-The following commands are available:
-* `findModulesCrossPkgBoundary` prints modules with inputs that cross package
-  boundaries
-* `findModulesWithNameSrcCollision` returns modules which have an input with the same
-  name as the module
-* `findModulesWithSrcType` returns modules with inputs with the specified extension
+Run `./query.sh` with no arguments for additional usage information.
