+# BlockstreamSatellite
+
+Ruby gem to interact with the [Blockstream Satellite](https://blockstream.com/satellite/) API.  
+
+To learn more about the Blockstream Satellite check their [website](https://blockstream.com/satellite/) and [API documentation](https://blockstream.com/satellite-api/).
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+```ruby
+gem 'blockstream_satellite'
+```
+
+Or install it yourself as:
+
+    $ gem install blockstream_satellite
+
+
+## Usage
+
+### Quick example
+
+```ruby
+order = BlockstreamSatellite::Order.create(path: '/path/to/file')
+puts order.status # pending
+order.pay # sends the lightning payment using the configured lnd client; request is synchronous
+
+puts order.status # transmitting
+order.refresh
+puts order.status # sent
+```
+
+### Configuration
+
+In order to be able to pay for the lightninig invoice you need to connect to you lightning node.  
+(By default the testnet cert and macaroon files are loaded from `~/.lnd` and `localhost:10009` is used)
+
+```ruby
+lnd_client = Lnrpc::Client.new({
+  credentials_path: '/path/to/tls.cert', 
+  macaroon_path: '/path/to/admin.macaroon', 
+  address: 'localhost:10009'
+})
+BlockstreamSatellite.lnd_client = lnd_client
+```
+
+### Creating an order
+
+`BlockstreamSatellite::Order.create` accepts the following parameters: 
+
+* `path`: path to the file to transmit
+* `data`: data to transmit; can be used as an alternative `path`
+* `bid`: bid for the order. defaults to file size * 51
+
+```ruby
+order = BlockstreamSatellite::Order.create(path: '/path/to/file')
+```
+
+### Loading an order by UUID and auth_token
+
+```ruby
+order = BlockstreamSatellite::Order.get(uuid: 'uuid', auth_token: 'auth_token')
+```
+
+### Bump the bid for an order
+
+```ruby
+order = BlockstreamSatellite::Order.get(uuid: 'uuid', auth_token: 'auth_token')
+order.bump(1000)
+```
+
+
+## Satus
+
+Currently I consider this gem experimental and it is missing tests current.  
+
+
+## Contributing
+
+Bug reports and pull requests are welcome on GitHub at https://github.com/[USERNAME]/blockstream_satellite.
+
+## License
+
