+## Indexing Large Files
+
+By default, Sourcebot will skip indexing files that are larger than 2MB or have more than 20,000 trigrams. You can configure this by setting the `maxFileSize` and `maxTrigramCount` [settings](/docs/configuration/config-file#settings).
+
+These limits can be ignored for specific files by passing in a comma separated list of glob patterns matching file paths to the `ALWAYS_INDEX_FILE_PATTERNS` environment variable. For example:
+
+```bash
+# Always index all .sum and .lock files
+ALWAYS_INDEX_FILE_PATTERNS=**/*.sum,**/*.lock
+```
+
+Files that have been skipped are assigned the `skipped` language. You can view a list of all skipped files by using the following query:
+```
+lang:skipped
+```
+
+## Indexing Binary Files
+
+Binary files cannot be indexed by Sourcebot. See [#575](https://github.com/sourcebot-dev/sourcebot/issues/575) for more information.
