+# 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`.

+
+This page covers how to Nomic's Atlas ecosystem within LangChain.
+It is broken into two parts: installation and setup, and then references to specific Atlas wrappers.
+
+## 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:
+```python
+from langchain.vectorstores import AtlasDB
+```

+# 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,
+        temperature=0.9,
+        early_stopping=True,
+        no_repeat_ngram_size=3,
+        num_beams=5,
+        length_penalty=1.5,
+        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
+```
+
+You can find a full example of a Banana app [here](https://github.com/conceptofmind/serverless-template-palmyra-base/blob/main/app.py).
+
+## Wrappers
+
+### LLM
+
+There exists an Banana LLM wrapper, which you can access with
+
+```python
+from langchain.llms import Banana
+```
+
+You need to provide a model key located in the dashboard:
+
+```python
+llm = Banana(model_key="YOUR_MODEL_KEY")
+```

 # Agents
 
 Agents use an LLM to determine which actions to take and in what order.
-An action can either be using a tool and observing its output, or returning to the user.
+An action can either be using a tool and observing its output, or returning a response to the user.
 For a list of easily loadable tools, see [here](tools.md).
 Here are the agents available in LangChain.

You can do this with multiple different vectordbs, and use the agent as a way to route between them. There are two different ways of doing this - you can either let the agent use the vectorstores as normal tools, or you can set `return_direct=True` to really just use the agent as a router."

 ## Sequential Chain
 This is a specific type of chain where multiple other chains are run in sequence, with the outputs being added as inputs
-to the next. A subtype of this type of chain is the `SimpleSequentialChain`, where all subchains have only one input and one output,
+to the next. A subtype of this type of chain is the [`SimpleSequentialChain`](./generic/sequential_chains.html#simplesequentialchain), where all subchains have only one input and one output,

-These are a subset of chains designed to work with documents. There are two pieces to consider:

-2. Use cases for these types of chains.

-For the first, please see [this documentation](combine_docs.md) for more detailed information on the types of chains LangChain supports.

+Indexes
+==========================
+
+Indexes refer to ways to structure documents so that LLMs can best interact with them.
+This module contains utility functions for working with documents, different types of indexes, and then examples for using those indexes in chains.
+LangChain provides common indices for working with data (most prominently support for vector databases).
+For more complicated index structures, it is worth checking out `GPTIndex <https://gpt-index.readthedocs.io/en/latest/index.html>`_.
+
+The following sections of documentation are provided:
+
+- `Getting Started <./indexes/getting_started.html>`_: An overview of all the functionality LangChain provides for working with indexes.
+
+- `Key Concepts <./indexes/key_concepts.html>`_: A conceptual guide going over the various concepts related to indexes and the tools needed to create them.
+
+- `How-To Guides <./indexes/how_to_guides.html>`_: A collection of how-to guides. These highlight how to use all the relevant tools, the different types of vector databases, and how to use indexes in chains.
