+# Sidecar files
+
+When scanning, sist2 will read metadata from `.s2meta` JSON files and overwrite the 
+original document's metadata. Sidecar metadata files will also work inside archives.
+Sidecar files themselves are not saved in the index.
+
+This feature is useful to leverage third-party applications such as speech-to-text or
+OCR to add additional metadata to a file.
+
+**Example**
+
+```
+~/Documents/
+├── Video.mp4
+└── Video.mp4.s2meta
+```
+
+The sidecar file must have exactly the same file path and the `.s2meta` suffix.
+
+`Video.mp4.s2meta`:
+```json
+{
+  "content": "This sidecar file will overwrite some metadata fields of Video.mp4",
+  "author": "Some author",
+  "duration": 12345,
+  "bitrate": 67890,
+  "some_arbitrary_field": [1,2,3]
+}
+```
+
+```
+sist2 scan ~/Documents -o ./docs.idx
+sist2 index ./docs.idx
+```
+
+*NOTE*: It is technically possible to overwrite the `tag` value using sidecar files, however,
+it is not currently possible to restore both manual tags and sidecar tags without user scripts
+while reindexing.
