+This directory contains docs and helper scripts for developing and debugging:
+
+- [`dev.sh`](./dev.sh): misc dev helpers
+- [`dev-features.sh`](./dev-features.sh): helpers for developing specific
+  nix-bitcoin features, like services
+- [`topics`](./topics) features specific topics
+- [`dev-scenarios.nix`](./dev-scenarios.nix): extra test scenarios used in the above scripts
+
+See also: [test/README.md](../test/README.md)
+
+## Run a dev shell
+
+There are two ways to run a dev shell:
+
+### 1. Run command `nix develop`
+
+This starts a shell with [`test/run-tests.sh`](../test/run-tests.sh) and
+the scripts in dir [`helper`](../helper) added to `PATH`.
+
+### 2. Setup and start the `direnv` dev env
+
+This is an opinionated, [direnv](https://direnv.net/)-based dev env, optimized for developer experience.
+
+[`dev-env/create.sh`](./dev-env/create.sh) creates a git repo with the following contents:
+- Dir `src` which contains the nix-bitcoin repo
+- Dir `bin` for helper scripts
+- File `scenarios.nix` for custom test scenarios
+- File `.envrc` that defines a [direnv](https://direnv.net/) environment,
+  mainly for adding nix-bitcoin and helper scripts to `PATH`
+
+#### Installation
+
+1. [Install direnv](https://direnv.net/docs/installation.html).\
+   If you use NixOS (and Bash as the default shell), just add the following to your system config:
+   ```nix
+     environment.systemPackages = [ pkgs.direnv ];
+     programs.bash.interactiveShellInit = ''
+       eval "$(direnv hook bash)"
+     '';
+   ```
+
+2. Create the dev env:
+   ```bash
+   # Set up a dev environment in dir ~/dev/nix-bitcoin.
+   # The dir is created automatically.
+   ./dev-env/create.sh ~/dev/nix-bitcoin
+
+   cd ~/dev/nix-bitcoin
+
+   # Enable direnv
+   direnv allow
+   ```
+
+3. Optional: Editor integration
+   - Add envrc support to your editor
+   - Setup your editor so you can easily execute lines or paragraphs from a shell script
+     file in a shell.\
+     This simplifies using dev helper scripts like [`./dev.sh`](./dev.sh).
+
+#### Explore the dev env
+```bash
+# The direnv is automatically activated when visiting any subdir of ~/dev/nix-bitcoin
+cd ~/dev/nix-bitcoin
+
+ls -al . bin lib
+
+# The direnv config file
+cat .envrc
+
+# You can use this file to define extra scenarios
+cat scenarios.nix
+
+# Binary `dev-run-tests` runs nix-bitcoin's `run-tests.sh` with extra scenarios from ./scenarios.nix
+# Example:
+# Run command `nodeinfo` in `myscenario` (defined in ./scenarios.nix) via a container
+dev-run-tests -s myscenario container --run c nodeinfo
+
+# Equivalent (shorthand)
+te -s myscenario container --run c nodeinfo
+
+# Run the tests for `myscenario` in a VM
+te -s myscenario
+
+# Start an interactive shell inside a VM
+te -s myscenario vm
+```
+
+See also: [test/README.md](../test/README.md)
+
+## Adding a new service
+
+It's easiest to use an existing service as a template:
+- [electrs.nix](../modules/electrs.nix): a basic service
+- [clightning.nix](../modules/clightning.nix): simple, but covers a few more features.\
+  (A `cli` binary and a runtime-composed config to include secrets.)
+- [rtl.nix](../modules/rtl.nix): includes a custom package, defined in [pkgs/rtl](../pkgs/rtl).\
+  Most other services use packages that are already included in nixpkgs.
+
+## Switching to a new NixOS release
+
+- [flake.nix](../flake.nix): update `nixpkgs.url`
+- [cirrus.yml](../.cirrus.yml): update toplevel container -> image attribute
+- [examples/configuration.nix](../examples/configuration.nix): update `system.stateVersion`
+- Treewide: check if any `TODO-EXTERNAL` comments can be resolved

+- Create a plain text URL:
+  ```bash
+  lndconnect --url

+- Set a custom host. By default, `lndconnect` detects the system's external IP and uses it as the host.
+  ```bash
+  lndconnect --host myhost
+  ```
+
+# Use Zeus (mobile lightning wallet) via WireGuard
+
+Connecting Zeus directly to your node is much faster than using Tor, but a bit more complex to setup.
+
+There are two ways to establish a secure, direct connection:
+
+- Connecting via TLS. This requires installing your lightning app's
+  TLS Certificate on your mobile device.
+
+- Connecting via WireGuard. This approach is simpler and more versatile, and is
+  described in this guide.
+
+1. Install [Zeus](https://zeusln.app) (version ≥ 0.7.1) and
+   [WireGuard](https://www.wireguard.com/install/) on your mobile device.
+
+2. Add the following to your `configuration.nix`:
+   ```nix
+   imports = [
+     # Use this line when using the default deployment method
+     <nix-bitcoin/modules/presets/wireguard.nix>
+
+     # Use this line when using Flakes
+     (nix-bitcoin + /modules/presets/wireguard.nix)
+   ]

+
+   # For clightning
+   services.clightning-rest = {
+     enable = true;
+     lndconnect.enable = true;
+   };
+   ```
+3. Deploy your configuration.
+
+4. If your node is behind an external firewall or NAT, add the following port forwarding
+   rule to the external device:
+   - Port: 51820 (the default value of option `networking.wireguard.interfaces.wg-nb.listenPort`)
+   - Protocol: UDP
+   - Destination: IP of your node
+
+5. Setup WireGuard on your mobile device.
+
+   Run the following command on your node (as user `operator`) to create a QR code
+   for WireGuard:
+   ```bash
+   nix-bitcoin-wg-connect
+
+   # For debugging: Show the WireGuard config as text
+   nix-bitcoin-wg-connect --text
+   ```
+   The above commands automatically detect your node's external IP.\
+   To set a custom IP or hostname, run the following:
+   ```
+   nix-bitcoin-wg-connect 93.184.216.34
+   nix-bitcoin-wg-connect mynode.org
+   ```
+
+   Configure WireGuard:
+   - Press the `+` button in the bottom right corner
+   - Scan the QR code
+   - Add the tunnel
+
+6. Setup Zeus
+
+   Run the following command on your node (as user `operator`) to create a QR code for Zeus:
+
+   ##### For lnd
+   ```
+   lndconnect-wg
+   ```
+
+   ##### For clightning
+   ```
+   lndconnect-clightning-wg
+   ```
+
+   Configure Zeus:
+   - Add a new node and scan the QR code
+   - Click `Save node config`
+   - On the certificate warning screen, click `I understand, save node config`.\

+The [`run-tests.sh`](./run-tests.sh) command is most convenient and versatile way to run tests.\
+It leave no traces (outside of `/nix/store`) on the host system.
+
+`run-tests.sh` requires Nix >= 2.10.
+
+### Summary
+```bash
+./run-tests.sh [--scenario|-s <scenario>] [build|vm|debug|container]
+```
+
+See the top of [run-tests.sh](../test/run-tests.sh) for a complete documentation.\
+Test scenarios are defined in [tests.nix](./tests.nix) and [tests.py](tests.py).
+
+### Tutorial
+#### Running tests
+```bash
+# Run the basic set of tests. These tests are also run on the GitHub CI server.
+./run-tests.sh
+
+# Run the test for scenario `regtest`.
+# The test is run via the Nix build system. Successful runs are cached.
+./run-tests.sh -s regtest build
+./run-tests.sh -s regtest # Shorthand, equivalent
+
+# To test a single service, use its name as a scenario.
+./run-tests.sh -s clightning
+
+# When no scenario is specified, scenario `default` is used.
+./run-tests.sh build
+```
+#### Debugging
+```bash
+# Start a shell is inside a test VM. No tests are executed.
+./run-tests.sh -s bitcoind vm
+systemctl status bitcoind
+
+# Run a Python NixOS test shell inside a VM.
+# See https://nixos.org/manual/nixos/stable/#ssec-machine-objects for available commands.
+./run-tests.sh debug
+print(succeed("systemctl status bitcoind"))
+run_test("bitcoind")
+
+# Start a shell in a container node. Requires systemd and root privileges.
+./run-tests.sh container
+
+# In the container shell: Run command in container (with prefix `c`)
+c systemctl status bitcoind
+
+# Explore a single feature
+./run-tests.sh -s electrs container
+
+# Run a command in a container.
+# The container is deleted afterwards.
+./run-tests.sh -s clightning container --run c lightning-cli getinfo
+
+# Define a custom scenario
+./run-tests.sh --scenario '{
+  services.clightning.enable = true;
+  nix-bitcoin.nodeinfo.enable = true;
+}' container --run c nodeinfo
+```
+
+# Running tests with Flakes
+
+Tests can also be accessed via the nix-bitcoin flake:
+
+```bash
+# Build test
+nix build --no-link ..#tests.default
+
+# Run a node in a VM. No tests are executed.
+nix run ..#tests.default.vm
+
+# Run a Python test shell inside a VM node

+
+# Run a node in a container. Requires extra-container, systemd and root privileges
