 A Python library for working with STAC Catalogs via Pandas DataFrames
 
+## Installation
+
+Install via pip:
+
+```shell
+pip install stacframes
+```
+
+## Usage
+
+To load a STAC Catalog into a GeoDataFrame:
+
+```python
+import pystac
+import stacframes
+
+catalog = pystac.Catalog.from_file("path/to/catalog.json")
+df = stacframes.df_from(catalog)
+```
+
+To write a DataFrame to a STAC Catalog:
+
+```python
+from datetime import datetime, timezone
+import pandas as pd
+import pystac
+from shapely.geometry import box
+import stacframes
+
+df = pd.read_csv("path/to/data.csv")
+
+# Filter, map, edit dataframe as desired
+
+# Map dataframe rows
+def map_row_to_item(series):
+
+    # Get and transform necessary column values from series
+    geometry = series["geom"]
+    dt = series["event_time"]
+
+    return {
+      "id": series["uuid"]
+      "geometry": geometry
+      "bbox": list(geometry.bounds)
+      "datetime": dt
+    }
+
+catalog = pystac.Catalog("data", "My Data")
+stacframes.df_to(catalog, df.apply(map_row_to_item))
+catalog.normalize_and_save("./path/to/catalog.json")
+```
+
+Please take a look at [the source code](https://github.com/azavea/stacframes/blob/master/stacframes/__init__.py) for more examples and additional documentation.
+
+## Developing
+
+Install the development requirements:
+
+```shell
+pip install -r requirements-dev.txt
+```
+
+Make changes as desired, then run:
+
+```shell
+./scripts/test
+```
+
+## Releasing a new version
+
+Follow the checklist in [RELEASE.md](./RELEASE.md)

+# AVIRIS Example
+
+This example uses `stacframes` to construct a STAC Catalog for the [NASA JPL AVIRIS dataset](https://aviris.jpl.nasa.gov).
+
+It requires the following python packages to run:
+
+```shell
+stacframes
+fastkml
+jsonschema
+```
+
+Open a terminal in this directory, then generate the catalog with `python main.py`. 
+
+The catalog will be written to `./catalog/catalog.json`.
