# Chroma

> Batch process all your records using `unstructured-ingest` to store structured outputs locally on your filesystem and upload those to a Chroma database.

First you’ll need to install the Chroma dependencies as shown here.

```bash
pip install "unstructured[chroma]"

```

## Run Locally

The upstream connector can be any of the ones supported, but for convenience here, showing a sample command using the upstream local connector.

<CodeGroup>
  ```bash Shell
  #!/usr/bin/env bash

  unstructured-ingest \
    local \
    --input-path example-docs/book-war-and-peace-1p.txt \
    --output-dir local-to-chroma \
    --strategy fast \
    --chunk-elements \
    --embedding-provider "<unstructured embedding provider, ie. langchain-huggingface>" \
    --num-processes 2 \
    --verbose \
    --work-dir "<directory for intermediate outputs to be saved>" \
    chroma \
    --host "localhost" \
    --port 8000 \
    --collection-name "collection name" \
    --tenant "default_tenant" \
    --database "default_database" \
    --batch-size 80
  ```

NOTE: Keep in mind that you will need to have all the appropriate extras and dependencies for the file types of the documents contained in your data storage platform if you’re running this locally. You can find more information about this in the [installation guide](/open-source/installation/overview).
