+# Evaluation
+
+This section of documentation covers how we approach and think about evaluation in LangChain.
+Both evaluation of internal chains/agents, but also how we would recommend people building on top of LangChain approach evaluation.
+
+## The Problem
+
+It can be really hard to evaluate LangChain chains and agents.
+There are two main reasons for this:
+
+**# 1: Lack of data**
+
+You generally don't have a ton of data to evaluate your chains/agents over before starting a project.
+This is usually because Large Language Models (the core of most chains/agents) are terrific few-shot and zero shot learners,
+meaning you are almost always able to get started on a particular task (text-to-SQL, question answering, etc) without
+a large dataset of examples.
+This is in stark contrast to traditional machine learning where you had to first collect a bunch of datapoints
+before even getting started using a model.
+
+**# 2: Lack of metrics**
+
+Most chains/agents are performing tasks for which there are not very good metrics to evaluate performance.
+For example, one of the most common use cases is generating text of some form.
+Evaluating generated text is much more complicated than evaluating a classification prediction, or a numeric prediction.
+
+## The Solution
+
+LangChain attempts to tackle both of those issues.
+What we have so far are initial passes at solutions - we do not think we have a perfect solution.
+So we very much welcome feedback, contributions, integrations, and thoughts on this.
+
+Here is what we have for each problem so far:
+
+**# 1: Lack of data**
+
+We have started [LangChainDatasets](https://huggingface.co/LangChainDatasets) a Community space on Hugging Face.
+We intend this to be a collection of open source datasets for evaluating common chains and agents.
+We have contributed five datasets of our own to start, but we highly intend this to be a community effort.
+In order to contribute a dataset, you simply need to join the community and then you will be able to upload datasets.
+
+We're also aiming to make it as easy as possible for people to create their own datasets.
+As a first pass at this, we've added a QAGenerationChain, which given a document comes up
+with question-answer pairs that can be used to evaluate question-answering tasks over that document down the line.
+See [this notebook](/docs/guides/evaluation/qa_generation.html) for an example of how to use this chain.
+
+**# 2: Lack of metrics**
+
+We have two solutions to the lack of metrics.
+
+The first solution is to use no metrics, and rather just rely on looking at results by eye to get a sense for how the chain/agent is performing.
+To assist in this, we have developed (and will continue to develop) [tracing](/docs/guides/tracing/), a UI-based visualizer of your chain and agent runs.
+
+The second solution we recommend is to use Language Models themselves to evaluate outputs.
+For this we have a few different chains and prompts aimed at tackling this issue.
+
+## The Examples
+
+We have created a bunch of examples combining the above two solutions to show how we internally evaluate chains and agents when we are developing.
+In addition to the examples we've curated, we also highly welcome contributions here.
+To facilitate that, we've included a [template notebook](/docs/guides/evaluation/benchmarking_template.html) for community members to use to build their own examples.
+
+The existing examples we have are:
+
+[Question Answering (State of Union)](/docs/guides/evaluation/qa_benchmarking_sota.html): A notebook showing evaluation of a question-answering task over a State-of-the-Union address.
+
+[Question Answering (Paul Graham Essay)](/docs/guides/evaluation/qa_benchmarking_pg.html): A notebook showing evaluation of a question-answering task over a Paul Graham essay.
+
+[SQL Question Answering (Chinook)](/docs/guides/evaluation/sql_qa_benchmarking_chinook.html): A notebook showing evaluation of a question-answering task over a SQL database (the Chinook database).
+
