+
+PHP class for the geobuf compact geospatial format
+
+## Installation
+
+```bash
+composer require mbolli/php-geobuf
+```
+
+## Usage
+
+```php
+
+```
+
+## Background: Proto compilation
+
+Classes were generated by the [proto compiler](https://developers.google.com/protocol-buffers) using this command:
+
+```bash
+bin/protoc --proto_path=src --php_out=build src/geobuf.proto
+```
+
+And [this proto file](./geobuf.proto) (lightly modified from the [mapbox/geobuf proto file](https://github.com/mapbox/geobuf/blob/master/geobuf.proto) for proto3 compatibility).
