 Infrastructure is essential, but it shouldn’t be your core business. Harmony is built on three guiding principles that make modern platforms reliable, repeatable, and easy to reason about.
 
-| Principle | What it means for you |
-|-----------|-----------------------|
-| **Infrastructure as Resilient Code** | Replace sprawling YAML and bash scripts with type-safe Rust. Test, refactor, and version your platform just like application code. |
-| **Prove It Works — Before You Deploy** | Harmony uses the compiler to verify that your application’s needs match the target environment’s capabilities at **compile-time**, eliminating an entire class of runtime outages. |
-| **One Unified Model** | Software and infrastructure are a single system. Harmony models them together, enabling deep automation—from bare-metal servers to Kubernetes workloads—with zero context switching. |

+# Architecture Decision Record: Monitoring Notifications
+
+Initial Author: Taha Hawa
+
+Initial Date: 2025-06-26
+
+Last Updated Date: 2025-06-26
+
+## Status
+
+Proposed
+
+## Context
+
+We need to send notifications (typically from AlertManager/Prometheus) and we need to receive said notifications on mobile devices for sure in some way, whether it's push messages, SMS, phone call, email, etc or all of the above.
+
+## Decision
+
+We should go with https://ntfy.sh except host it ourselves.
+
+`ntfy` is an open source solution written in Go that has the features we need.
+
+## Rationale
+
+`ntfy` has pretty much everything we need (push notifications, email forwarding, receives via webhook), and nothing/not much we don't. Good fit, lightweight.
+
+## Consequences
+
+Pros:
+
+- topics, with ACLs
+- lightweight
+- reliable
+- easy to configure
+- mobile app
+  - the mobile app can listen via websocket, poll, or receive via Firebase/GCM on Android, or similar on iOS.
+- Forward to email
+- Text-to-Speech phone call messages using Twilio integration
+- Operates based on simple HTTP requests/Webhooks, easily usable via AlertManager
+
+Cons:
+
+- No SMS pushes
+- SQLite DB, makes it harder to HA/scale
+
+## Alternatives considered
+
+[AWS SNS](https://aws.amazon.com/sns/):
+Pros:
+
+- highly reliable
+- no hosting needed
+
+Cons:
+
+- no control, not self hosted
+- costs (per usage)
+
+[Apprise](https://github.com/caronc/apprise):
+Pros:
+
+- Way more ways of sending notifications
+- Can use ntfy as one of the backends/ways of sending
+
+Cons:
+
+- Way too overkill for what we need in terms of features
+
+[Gotify](https://github.com/gotify/server):
+Pros:
+
+- simple, lightweight, golang, etc
+
+Cons:
+
+- Pushes topics are per-user

+# Leptos Starter Template
+
+This is a template for use with the [Leptos](https://github.com/leptos-rs/leptos) web framework and the [cargo-leptos](https://github.com/akesson/cargo-leptos) tool.
+
+## Creating your template repo
+
+If you don't have `cargo-leptos` installed you can install it with
+
+`cargo install cargo-leptos --locked`
+
+Then run
+
+`cargo leptos new --git leptos-rs/start-actix`
+
+to generate a new project template (you will be prompted to enter a project name).
+
+`cd {projectname}`
+
+to go to your newly created project.
+
+Of course, you should explore around the project structure, but the best place to start with your application code is in `src/app.rs`.
+
+## Running your project
+
+`cargo leptos watch`  
+By default, you can access your local project at `http://localhost:3000`
+
+## Installing Additional Tools
+
+By default, `cargo-leptos` uses `nightly` Rust, `cargo-generate`, and `sass`. If you run into any trouble, you may need to install one or more of these tools.
+
+1. `rustup toolchain install nightly --allow-downgrade` - make sure you have Rust nightly
+2. `rustup target add wasm32-unknown-unknown` - add the ability to compile Rust to WebAssembly
+3. `cargo install cargo-generate` - install `cargo-generate` binary (should be installed automatically in future)
+4. `npm install -g sass` - install `dart-sass` (should be optional in future)
+
+## Executing a Server on a Remote Machine Without the Toolchain
+After running a `cargo leptos build --release` the minimum files needed are:
+
+1. The server binary located in `target/server/release`
+2. The `site` directory and all files within located in `target/site`
+
+Copy these files to your remote server. The directory structure should be:
+```text
+leptos_start
+site/
+```
+Set the following environment variables (updating for your project as needed):
+```sh
+export LEPTOS_OUTPUT_NAME="leptos_start"
+export LEPTOS_SITE_ROOT="site"
+export LEPTOS_SITE_PKG_DIR="pkg"
+export LEPTOS_SITE_ADDR="127.0.0.1:3000"
+export LEPTOS_RELOAD_PORT="3001"
+```
+Finally, run the server binary.
+
+## Notes about CSR and Trunk:
+Although it is not recommended, you can also run your project without server integration using the feature `csr` and `trunk serve`:
+
+`trunk serve --open --features csr`
+
+This may be useful for integrating external tools which require a static site, e.g. `tauri`.
+
+## Licensing
+
+This template itself is released under the Unlicense. You should replace the LICENSE for your own application with an appropriate license if you plan to release it publicly.
