+# 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.
