+title: Subgrounds
+---
+
+Subgrounds is an intuitive Python library for querying subgraphs, built by [Playgrounds](https://playgrounds.network/). It allows you to directly connect subgraph data to a Python data environment, letting you use libraries like [pandas](https://pandas.pydata.org/) to perform data analysis!
+
+Subgrounds offers a simple Pythonic API for building GraphQL queries, automates tedious workflows such as pagination, and empowers advanced users through controlled schema transformations.
+
+## Getting Started
+
+Subgrounds requires Python 3.10 or higher and is available on [pypi](https://pypi.org/project/subgrounds/).
+
+```bash
+pip install --upgrade subgrounds
+# or
+python -m pip install --upgrade subgrounds
+```
+
+Once installed, you can test out subgrounds with the following query. The following example grabs a subgraph for the Aave v2 protocol and queries the top 5 markets ordered by TVL (Total Value Locked), selects their name and their TVL (in USD) and returns the data as a pandas [DataFrame](https://pandas.pydata.org/pandas-docs/dev/reference/api/pandas.DataFrame.html#pandas.DataFrame).
+
+```python
+from subgrounds import Subgrounds
+
+sg = Subgrounds()
+
+# Load the subgraph
+aave_v2 = sg.load_subgraph(
+    "https://api.thegraph.com/subgraphs/name/messari/aave-v2-ethereum")
+
+# Construct the query
+latest_markets = aave_v2.Query.markets(
+    orderBy=aave_v2.Market.totalValueLockedUSD,
+    orderDirection='desc',
+    first=5,
+)
+# Return query to a dataframe
+sg.query_df([
+    latest_markets.name,
+    latest_markets.totalValueLockedUSD,
+])
+```
+
+## Documentation
+
+Subgrounds is built and maintained by the [Playgrounds](https://playgrounds.network/) team and can be accessed on the [Playgrounds docs](https://docs.playgrounds.network/subgrounds).
