+### Description
+
+Verify WebM(s) Against AnimeThemes Encoding Standards
+
+Executes a test suite on the input WebM(s) to verify compliance.
+
+Test success/failure does **NOT** guarantee acceptance/rejection of submissions. In some tests, we are determining the correctness of our file properties. In other tests, we are flagging uncommon property values for inspection.
+
+### Install
+
+**Requirements:**
+
+* FFmpeg
+* Python >= 3.6
+
+**Install:**
+
+    pip install animethemes-webm-verifier
+
+### Usage
+
+    python -m test_webm [-h] [--loglevel [{debug,info,error}] [file [file ...]]
+
+* `--loglevel error`: Only show error messages
+* `--loglevel info`: Show error messages and script progression info messages
+* `--loglevel debug`: Show all messages, including variable dumps
+* `[file ...]`: The WebM(s) to verify. If not provided, we will test all WebMs in the current directory.
