+# Using Docker
+
+To quickly get started, run the command `make docker`.
+
+If docker is installed the Makefile will export extra targets in the fomrat `docker.*` to build and run the docker image. Type `make` for a list of available tasks.
+
+There is a basic `docker-compose.yml` in the docker directory.
+
+## Building the development image
+
+Using `make docker` will build the dev image if it does not exist, then drops
+you inside the container with the langchain environment available in the shell.
+
+### Customizing the image and installed dependencies
+
+The image is built with a default python version and all extras and dev
+dependencies. It can be customized by changing the variables in the [.env](/docker/.env)
+file. 
+
+If you don't need all the `extra` dependencies a slimmer image can be obtained by 
+commenting out `POETRY_EXTRA_PACKAGES` in the [.env](docker/.env) file.
+
+### Image caching
+
+The Dockerfile is optimized to cache the poetry install step. A rebuild is triggered when there a change to the source code.
+
+## Example Usage
+
+All commands from langchain's python environment are available by default in the container.
+
+A few examples:
+```bash
+# run jupyter notebook
+docker run --rm -it IMG jupyter notebook
+
+# run ipython
+docker run --rm -it IMG ipython
+
+# start web server
+docker run --rm -p 8888:8888 IMG python -m http.server 8888
+```
+
+## Testing / Linting
+
+Tests and lints are run using your local source directory that is mounted on the volume /src.
+
+Run unit tests in the container with `make docker.test`.
+
+Run the linting and formatting checks with `make docker.lint`.
+
+Note: this task can run in parallel using `make -j4 docker.lint`.

+## Installation and Setup
+- Install the Python package with `pip install nomic`
+- Nomic is also included in langchains poetry extras `poetry install -E all`
+- 
+## Wrappers
+
+### VectorStore
+
+There exists a wrapper around the Atlas neural database, allowing you to use it as a vectorstore.
+This vectorstore also gives you full access to the underlying AtlasProject object, which will allow you to use the full range of Atlas map interactions, such as bulk tagging and automatic topic modeling.
+Please see [the Nomic docs](https://docs.nomic.ai/atlas_api.html) for more detailed information.
+
+
+
+To import this vectorstore:

+# Banana
+
+This page covers how to use the Banana ecosystem within LangChain.
+It is broken into two parts: installation and setup, and then references to specific Banana wrappers.
+
+## Installation and Setup
+
+- Install with `pip3 install banana-dev`
+- Get an Banana api key and set it as an environment variable (`BANANA_API_KEY`)
+
+## Define your Banana Template
+
+If you want to use an available language model template you can find one [here](https://app.banana.dev/templates/conceptofmind/serverless-template-palmyra-base).
+This template uses the Palmyra-Base model by [Writer](https://writer.com/product/api/).
+You can check out an example Banana repository [here](https://github.com/conceptofmind/serverless-template-palmyra-base).
+
+## Build the Banana app
+
+Banana Apps must include the "output" key in the return json. 
+There is a rigid response structure.
+
+```python
+# Return the results as a dictionary
+result = {'output': result}
+```
+
+An example inference function would be:
+
+```python
+def inference(model_inputs:dict) -> dict:
+    global model
+    global tokenizer
+
+    # Parse out your arguments
+    prompt = model_inputs.get('prompt', None)
+    if prompt == None:
+        return {'message': "No prompt provided"}
+
+    # Run the model
+    input_ids = tokenizer.encode(prompt, return_tensors='pt').cuda()
+    output = model.generate(
+        input_ids,
+        max_length=100,
+        do_sample=True,
+        top_k=50,
+        top_p=0.95,
+        num_return_sequences=1,

+        repetition_penalty=1.5,
+        bad_words_ids=[[tokenizer.encode(' ', add_prefix_space=True)[0]]]
+        )
+
+    result = tokenizer.decode(output[0], skip_special_tokens=True)
+    # Return the results as a dictionary
+    result = {'output': result}
+    return result

+Document Loaders
+==========================
+
+Combining language models with your own text data is a powerful way to differentiate them.
+The first step in doing this is to load the data into "documents" - a fancy way of say some pieces of text.
+This module is aimed at making this easy.
+
+A primary driver of a lot of this is the `Unstructured <https://github.com/Unstructured-IO/unstructured>`_ python package.
+This package is a great way to transform all types of files - text, powerpoint, images, html, pdf, etc - into text data.
+
+For detailed instructions on how to get set up with Unstructured, see installation guidelines `here <https://github.com/Unstructured-IO/unstructured#coffee-getting-started>`_.
+
+The following sections of documentation are provided:
+
+- `Key Concepts <./document_loaders/key_concepts.html>`_: A conceptual guide going over the various concepts related to loading documents.
+
+- `How-To Guides <./document_loaders/how_to_guides.html>`_: A collection of how-to guides. These highlight different types of loaders.
