 instructions. Current targets:
 
   * `angle_deqp_gles2_tests` for GLES 2.0 tests

 ## How to use dEQP
 
-The `--deqp-case` flag allows you to run individual tests, with simple
-wildcard support. For example: `--deqp-case=dEQP-
+Note:
+To run an individual test, use the `--deqp-case` flag on any of the `no_gtest` targets.
+It supports simple wildcard support. For example: `--deqp-case=dEQP-
 GLES2.functional.shaders.linkage.*`.
+The `gtest` targets support wildcards via the `--gtest_filter` argument,
+but have different test names.
 
 The tests lists are sourced from the Android CTS masters in
 `third_party/deqp/src/android/cts/master`. See `gles2-master.txt`,
