+## Development Infrastructure
+
+The `docker/` directory contains a complete development environment:
+
+| Service       | Container             | Port(s)     | Description                           |
+| ------------- | --------------------- | ----------- | ------------------------------------- |
+| strfry        | lamassu-relay         | 7777        | Private Nostr relay                   |
+| bitcoind      | lamassu-bitcoind      | 18443       | Bitcoin Core (regtest)                |
+| LND           | lamassu-lnd           | 10009, 8080 | Lightning node (Lightning.Pub's node) |
+| LND Alice     | lamassu-lnd-alice     | 10010, 8081 | Second LND for payment testing        |
+| Lightning.Pub | lamassu-lightning-pub | 1776        | Nostr-native account system           |
+| PostgreSQL    | lamassu-postgres      | 5432        | Database for server-side state        |
+
+### Quick Start
+
+```bash
+devenv shell     # Enter dev environment
+infra-up         # Start all services (30-60s first run)
+mine-blocks 101  # Fund the regtest wallet
+setup-channel    # Open channel between Alice and LND
+```
+
+### Testing Payments
+
+The development setup includes two LND nodes to enable proper payment testing:
+
+1. **LND** (`lamassu-lnd`) - Used by Lightning.Pub to create invoices
+2. **Alice** (`lamassu-lnd-alice`) - Used to pay invoices (simulates external payers)
+
+```bash
+# Get Lightning.Pub admin token
+curl -X POST "http://localhost:1776/api/admin/app/auth" \
+  -H "Authorization: Bearer lamassu-dev-admin-token" \
+  -d '{"name": "wallet"}'
+
+# Create user and invoice
+curl -X POST "http://localhost:1776/api/app/user/add" -H "Authorization: Bearer $APP_TOKEN" \
+  -d '{"identifier": "test-user", "balance": 0}'
+
+curl -X POST "http://localhost:1776/api/app/user/add/invoice" -H "Authorization: Bearer $APP_TOKEN" \
+  -d '{"receiver_identifier": "test-user", "payer_identifier": "external", "http_callback_url": "", "invoice_req": {"amountSats": 1000, "memo": "Test"}}'
+
+# Pay from Alice
+alice-pay <invoice>
+```
+
+### MCP Tools Available
+
+Claude has access to these MCP servers for development:
+
+| MCP Server   | Purpose                                   |
+| ------------ | ----------------------------------------- |
+| docker-mcp   | Container management (logs, status, etc.) |
+| nostr-mcp    | Nostr operations (post notes, profiles)   |
+| postgres-mcp | Database queries and schema inspection    |
+| mcp-nixos    | NixOS/Nix package queries                 |
+| forgejo-mcp  | Git operations on Forgejo                 |
+
+Use these to interact with infrastructure directly during development.
