## Install
### Install standalone single-binary
```
wget https://github.com/pepa65/eqr/releases/download/1.8.44/qr
wget https://github.com/pepa65/eqr/releases/download/1.8.44/promptpay
sudo chown root:root qr promptpay
sudo chmod +x qr promptpay
sudo mv qr promptpay /usr/local/bin/
```

### Install with cargo
If not installed yet, install a **Rust toolchain**, see https://www.rust-lang.org/tools/install

#### Direct from crates.io
`cargo install eqr`

#### Direct from repo
`cargo install --git https://github.com/pepa65/eqr`

#### Static build (avoiding GLIBC incompatibilities)
```
git clone https://github.com/pepa65/eqr
cd eqr
rustup target add x86_64-unknown-linux-musl
cargo rel  # Alias in .cargo/config.toml
```

The binaries will be in `target/x86_64-unknown-linux-musl/release/`

### Install with cargo-binstall
Even without a full Rust toolchain, rust binaries can be installed with the static binary `cargo-binstall`:

```
# Install cargo-binstall for Linux x86_64
# (Other versions are available at https://crates.io/crates/cargo-binstall)
wget github.com/cargo-bins/cargo-binstall/releases/latest/download/cargo-binstall-x86_64-unknown-linux-musl.tgz
tar xf cargo-binstall-x86_64-unknown-linux-musl.tgz
sudo chown root:root cargo-binstall
sudo mv cargo-binstall /usr/local/bin/
```

Install the binaries for linux-x86_64 (musl): `cargo-binstall eqr`

The binaries will be installed into `~/.cargo/bin/` which still needs to be added to `PATH`!
