 ## Installation
 
-### Bare Metal (production)
-
 1. Set up a Redis instance
 2. Set up a signet network on a Bitcoin Core or Knots node. This node should have a wallet that receives the mining rewards or otherwise plenty of funds to give out. You can refer to [BcnBitcoinOnly/signet-playground](https://github.com/BcnBitcoinOnly/signet-playground) for more information.
 3. Clone this project, checkout the latest tag and install the PHP dependencies with `composer install --no-dev --classmap-authoritative`
 4. Set up a webserver with FastCGI support and configure it properly, including the faucet's environment variables (see below). Caddy is recommended for its ease of use.
 
-### Docker (development)
-
-For development tasks Docker, the PHP CLI and Composer are assumed to be installed locally.
-The development stack runs containerized Caddy and PHP-FPM containers, but Composer is used as a task runner tool.
-
-```shell
-$ docker compose up -d
-$ composer install
-$ composer setup
-```
-
-After these commands the faucet will be available at `http://localhost:8080`, and set up with a regtest node with a wallet and 101 blocks already mined.
-
-The `composer.json` file also has tasks for generating bitcoin addresses, mining new blocks and running the linter and the test suite.
-
-To customize the Docker stack create a `compose.override.yml` at the root. On `docker compose up -d` it'll be automatically merged with `compose.yml`.
-Example, with custom environment variables and exposed Redis port for debugging:
-
-```yaml
-name: faucet
-
-services:
- php-fpm:
- env_file:
- - .env
- redis:
- ports:
- - 127.0.0.1:6379:6379
-```
-
-To customize the default environment variables create an `.env` file and set it up as an extra `env_file` for `php-fpm` as shown above.
-Example:
-
-```
-FAUCET_USE_CAPTCHA=1
-FAUCET_PASSWORD_BCRYPT_HASH='$2y$10$MyYyMkeWk2v4tvzA5lylyuWBsBXsvOfcGeCG61C9mVOdXDx1/BnyO'
-```
-
-Changing environment variables requires recreating the `php-fpm` container.

 ## Configuration
 
 ### Environment Variable Reference
@@ -99,9 +57,28 @@ The following environment variables can be used to configure your faucet instanc
 | `FAUCET_PASSWORD_BCRYPT_HASH` | Bcrypt hash of the faucet's password | Read Password section | No |
 | `FAUCET_MEMPOOL_URL` | Mempool URL where to show the instant payout transactions | `https://mempool.example.com` | No |
 
+### Password
+
+In order to avoid storing plain text secrets the faucet settings use a BCrypt hash instead of the password itself.
+
+Run the `bin/bcrypt.php` helper script to get a ready-made `FAUCET_PASSWORD_BCRYPT_HASH` definition from any given password.
+
+```shell
+$ php bin/bcrypt.php n0s3c0ndb3st
+FAUCET_PASSWORD_BCRYPT_HASH='$2y$10$cNZwPXN5N8.RUBrMNfZOhuT9ClWv0fWawSaxE4rTXbgTjrNVJTko2'
+```

 ### Transaction Batching
 
-TODO
+![batched payment example](docs/img/batch.png)
+
+Transaction batching instructs the faucet to withhold approved payouts to send them later on as a single transaction.
+To enable this mode, set `FAUCET_USE_BATCHING=1`.
+
+You also need to set up a cronjob that runs `bin/batch.php` at your preferred interval.
+Run `crontab -e` to edit the current user's crontab file.
+
+In [`docs/cron`](docs/cron/sample) there's an example on how to set up one such cronjob that runs every 15 minutes.

+The `composer.json` file also has tasks for fetching new addresses from the node's wallet, mining additional regtest blocks, running the test suite and applying the code linter:
