+
+
+## Installation
+
+Install **prepembd**:
+
+```shell
+python3 -m pip install prepembd --upgrade
+```
+
+### Requirements
+
+- [Python](https://www.python.org/) >= 3.10
+
+## Why
+
+I've been using markdown now for a long time to take notes in every possible scenario. I even manage my Anki cards with markdown ([inka2](https://github.com/sysid/inka2)) so finding relevant information again is paramount.
+With the advent of semantic search via Embeddings search became so much more powerfull. However, to create the
+embeddings out of markdown the files have to be prepared in order to reduce noice and create the correct chunk sizes.
+
+This Python script automates the process and creates a json representation of all the markdown files which then can be fed into an embedding model. It is basically just a thin wrapper aroung LangChain combined with some bespoke filter to eliminated noise.
+
+
+## Usage
+```bash
+prepembd tokenize <directory> | tee -a output.ndjson
+```
