+# Running bitcoin-core and LND with Docker
+
+If you don't already have your own bitcoin node and lightning node, you can use docker-compose to launch new ones.
+
+##### Steps
+- Build and start docker-compose:
+	```
+	$ cd docker
+	$ docker-compose build
+	$ docker-compose up
+	```
+- If you want to use testnet, run the normal `up` command:
+	```
+	$ docker-compose up
+	```
+- If you want to use mainnet, run with the `docker-compose.mainnet.yml` override file:
+	```
+	$ docker-compose -f docker-compose.yml -f docker-compose.mainnet.yml up
+	```
