 # Qlock
 
 A minimal, curses-based clock, for your terminal. Inspired by the [QlockTwo by Biegert&Funk](https://qlocktwo.com/us/ "QlockTwo by Biegert&Funk").

+## Installing
+
+### Release binary
+
+Prebuilt binaries can be found on the [releases page][github-release-link]. Download the archive for your computer's architecture, extract the binary, and put it inside your `$PATH`.
+
+```bash
+$ wget -q https://github.com/joshdk/tty-qlock/releases/download/v1.0.0/qlock-linux-amd64.tar.gz
+$ tar -xf qlock-linux-amd64.tar.gz
+$ sudo install qlock /usr/bin/qlock
+```
+
+You can then launch qlock by running:
+
+```
+$ qlock -help
+```
+
+### From source
+
+Alternatively, you can build it yourself by cloning the repo, and then running:
+
+```bash
+$ make build
+```
+
+You can then launch qlock by running:
+
+```
+$ ./dist/qlock -help
+```
+
+## Usage
+
+### Help!
+
+You can pass the `-help` flag to display the help text:
+
+```
+$ qlock -help
+Usage of qlock:
+  -off-color string
+        color for disabled letters (default "black")
+  -on-color string
+        color for enabled letters (default "blue")
+  -version
+        print version and exit
+```
+
+### Colors
+
+You can pass the `-on-color` and `-off-color` flags to control the color of the enabled and disabled UI elements respectively.
+
+Both flags can take any of the 8 standard color names (`black`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`, or `white`).
+
+Additionally, a `+bold` suffix can be added to use the bold color variant (like `-color-on green+bold`).
+
