## Install

| Platform | Download |
|---|---|
| **macOS** (Apple Silicon) | [omacus-macos-arm64.dmg]($dl/omacus-macos-arm64.dmg) |
| **macOS** (Intel) | [omacus-macos-x86_64.dmg]($dl/omacus-macos-x86_64.dmg) |
| **Windows** (x64) | [omacus-windows-x86_64.zip]($dl/omacus-windows-x86_64.zip) |
| **Ubuntu / Debian** | [omacus-linux-x86_64.deb]($dl/omacus-linux-x86_64.deb) |
| **Fedora / openSUSE** | [omacus-linux-x86_64.rpm]($dl/omacus-linux-x86_64.rpm) |
| **Omarchy / Arch / any Linux** | [omacus-linux-x86_64.tar.gz]($dl/omacus-linux-x86_64.tar.gz) or the installer below |

**Omarchy** (installs the app, then offers a keybind, \`SUPER + CTRL + ALT + =\` by default, and a floating window rule):

\`\`\`sh
curl -fsSL https://omacus.com/install | bash
\`\`\`

**Any other Linux** (installs to \`~/.local/bin\` with a launcher entry):

\`\`\`sh
curl -fsSL https://omacus.com/install | bash
\`\`\`

**Ubuntu / Debian:** \`sudo apt install ./omacus-linux-x86_64.deb\`
**Fedora:** \`sudo dnf install ./omacus-linux-x86_64.rpm\`

**macOS:** open the \`.dmg\` and drag Omacus to Applications. It isn't notarized yet, so the first
time right-click the app and choose **Open**, or run \`xattr -dr com.apple.quarantine /Applications/Omacus.app\`.

**Windows:** unzip and run \`omacus.exe\`. If SmartScreen warns about an unknown publisher, choose
**More info → Run anyway**. It works from a terminal too: \`omacus.exe "\$100 in INR"\`.

Checksums are in \`SHA256SUMS.txt\`.
