+## Binary Installation
+
+git-cdflow provides 64-bit installation for GNU/Linux and Mac OS X.
+
+1. Download the tar.gz file for your platform from the [release page](https://github.com/Etiqa/git-cdflow/releases)
+2. Extract the archive
+```bash
+tar xvzf git-cdflow.tar.gz
+```
+3. `cd` to the directory you extracted the archive, for example `cd /Users/johndoe/git-cdflow`
+4. `cd` to the bin subdirectory `cd bin`
+5. Test that the toolkit is functional
+```bash
+./git-cdflow version
+```
+6. Append the git-cdflow bin directory to your `PATH` environment variable. There are different ways to do it, for example adding the following row to your `~/.bashrc` file
+```bash
+export PATH=$PATH:/Users/johndoe/git-cdflow/bin
+```
+7. Verify that the binaries will be found by the shell:
+```bash
+source ~/.bashrc
+which git-cdflow
+```
+8. Your configuration should be done and git-cdflow should be recognized as a git plugin, so you can run it without the dash:
+```bash
+git cdflow help
+```
