+#### Filtering subtitle text
+
+If you'd like to filter out specific instances subtitle text, one way to do so is by using a regular expression (regex). asbplayer can match any sequence following a specified regex pattern and remove the matches.
+
+Under the MISC section in asbplayer settings, locate the "Subtitle regex filter" textbox. Enter an appropriate regex to filter desired content.
+You can replace filtered content similarly by entering a string into the "Subtitle regex filter text replacement" textbox. Leaving this blank will simply remove the content.
+
+Useful examples of regular expressions:
+ - `(\(|（).*(\)|）)` : Remove names enclosed by parenthesis to indicate speakers  (i.e. "**（山田）**　元気ですか？")
+ - `\[.*\]` : Remove indications enclosed by brackets that sound or music that is playing (i.e. "**\[PLAYFUL MUSIC]**")
+
+Learn how to write and test custom regular expressions at [Regex Learn - Playground](https://regexlearn.com/playground).
+
+#### Downloading subtitle files
+
+Once loaded into the extension, you can download the subtitles by opening the side panel and clicking the `Download Subtitles as SRT` button in the top-right. You can also download subtitles via the website by clicking the same download button in the top-left.
+
+> Note: Using the [regex feature](#filtering-subtitle-text) will alter the .srt that is downloaded.
