+
+# Building (Linux)
+
+- Clone this repo `git clone "https://git.maidsin.space/catto/snotes.git"`
+- [Install Rust](https://www.rust-lang.org/learn/get-started)
+- run `carog build --release` in the root of the project
+- You now have a working `snotes` binary file under `target/release`
+
+Windows Builds might be a bit more involved since this dependency builds and bundles sqlite3 [https://github.com/rusqlite/rusqlite](https://github.com/rusqlite/rusqlite)
+
+# Installation
+
+You could copy the `snotes` binary into a `/usr/bin` or `~/.local/bin` folder, one that's part of your system PATH so you can run it anywhere.
