+# async-template
+
+![async template demo](https://user-images.githubusercontent.com/1813121/277114001-0d25a09c-f24e-4ffc-8763-cd258828cec0.gif)
+
+## Usage
+
+You can start by using `cargo-generate`:
+
+```shell
+cargo install cargo-generate
+cargo generate ratatui-org/templates async --name ratatui-hello-world
+cd ratatui-hello-world
+```
+
+## Features
+
+- Uses [tokio](https://tokio.rs/) for async events
+  - Start and stop key events to shell out to another TUI like vim
+  - Supports suspend signal hooks
+- Logs using [tracing](https://github.com/tokio-rs/tracing)
+- [better-panic](https://github.com/mitsuhiko/better-panic)
+- [color-eyre](https://github.com/eyre/color-eyre)
+- [human-panic](https://github.com/rust-cli/human-panic)
+- Clap for command line argument parsing
+- `Component` trait with
+  [`Home`](https://github.com/ratatui-org/async-template/blob/main/template/src/components/home.rs)
+  and
+  [`Fps`](https://github.com/ratatui-org/async-template/blob/main/template/src/components/fps.rs)
+  components as examples
+
+## Advanced Usage
+
+You can also use a
+[`template.toml`](https://github.com/ratatui-org/async-template/blob/main/.github/workflows/template.toml)
+file to skip the prompts:
+
+```bash
+$ cargo generate --git https://github.com/ratatui-org/async-template --template-values-file .github/workflows/template.toml --name ratatui-hello-world
+# OR generate from local clone
+$ cargo generate --path . --template-values-file .github/workflows/template.toml --name ratatui-hello-world
+```
+
+## Running your App
+
+```bash
+cargo run # Press `q` to exit
+```
+
+## Show help
+
+```bash
+$ cargo run -- --help
+Hello World project using ratatui-template
+
+Usage: ratatui-hello-world [OPTIONS]
+
+Options:
+  -t, --tick-rate <FLOAT>   Tick rate, i.e. number of ticks per second [default: 1]
+  -f, --frame-rate <FLOAT>  Frame rate, i.e. number of frames per second [default: 60]
+  -h, --help                Print help
+  -V, --version             Print version
+```
+
+## Show `version`
+
+Without direnv variables:
+
+```bash
+$ cargo run -- --version
+    Finished dev [unoptimized + debuginfo] target(s) in 0.07s
+     Running `target/debug/ratatui-hello-world --version`

+
+## Counter + Text Input Demo
+
+This repo contains a `ratatui-counter` folder that is a working demo as an example. If you wish to
+run a demo without using `cargo generate`, you can run the counter + text input demo by following
+the instructions below:
+
+```bash
+git clone https://github.com/ratatui-org/async-template
+cd async-template
+cd ratatui-counter # counter + text input demo
+
+export RATATUI_COUNTER_CONFIG=`pwd`/.config
+export RATATUI_COUNTER_DATA=`pwd`/.data
+export RATATUI_COUNTER_LOG_LEVEL=debug
+# OR
+direnv allow
+
+cargo run
+```
+
+You should see a demo like this:
