 Convert podcast transcripts from HTML, SRT, WebVtt, Podlove etc into [PodcastIndex JSON](https://github.com/Podcastindex-org/podcast-namespace/blob/main/transcripts/transcripts.md).
 
 
+## Installation
+
+It is recommended to use [pipx](https://pipx.pypa.io/stable/) to install and run the CLI tool. If you wish to use the library, you can install with `pip` instead.
+
+```bash
+brew install pipx
+pipx install podcast-transcript-convert
+```
+
+## Usage
+Run the conversion app on your transcripts directory.
+
+```bash
+transcript2json transcripts/ converted/
+```
+You can then inspect the output JSON files in the `converted/` directory.
+
+## Library Usage
+```python
+from podcast_transcript_convert.convert import bulk_convert
+
+bulk_convert("transctipts_dir/", "converted_dir/")
+```
+
+Individual file type converters are in the `converters` package. You can use them directly if you know the file type.
+
+You can use `file_typing.identify_file_type(file)` to determine the file type of a transcript file.
