+# Counterweight V2
+
+This is the repo where I store everything necessary to spin up my
+Bitcoin-related node.
+
+It currently includes:
+
+- Bitcoin core
+- electrs
+- mempool block explorer
+- lnbits
+
+## How to deploy
+
+### Requirements
+
+These instructions assume you are on a debian/ubuntu machine with docker,
+docker compose and git installed.
+
+### Cloning
+
+First, clone this repo where you would like to run your node.
+
+### Building electrs
+
+TODO: explain
+
+### Environment and configuration files
+
+Now, you need to build a `.env` file. You can start by making a copy of
+`.env-example` and filling it.
+
+Afterwards, create the `data` folder in the root of the cloned repo. Inside,
+create the folders `bitcoin`, `electrs`, `mempool` and `lnbits`.
+
+Inside `data/bitcoin`, you will need to place a `bitcoin.conf` file. You can
+use the example in `config_templates/bitcoin.conf`. Ensure that your inputs
+here are consistent with the ones in the `.env` file.
+
+Inside `data/electrs/config`, you will need to place a `config.toml` file. You
+can use the example in `config_templates/config.toml`. For this one, you should
+not make any changes if you are following these instructions.
+
+Inside `data/lnbits`, you will need to place a `.env` file. Pay attention: this
+file is specific for LNbits and is unrelated to the other `.env` file that sits
+on the root of this repo. TODO: make template in 
+
+
+### Smoke testing
+
+TODO: describe how to check that everything is warning.
+
+## Upgrading versions of the different services
+
+- Bitcoin: upgrade in docker-compose.yaml.
+- electrs: specify tag in custom electrs dockerfile, build again.
+- mempool: upgrade web, api and db in docker-compose.yaml.
+- LNbits: upgrade in docker-compose.yaml.
+
+
+### How to backup data
+
+TODO: explain how to back all the data up with a rsync.
