+There are two ways to install WTF:
+
+## From Source
+
+Clone this repo:
+
+```bash
+git clone git@github.com:senorprogrammer/wtf.git
+```
+
+`cd` into that `wtf/` directory and run:
+
+```bash
+make install
+```
+
+and that should probably do it.
+
+## As a Binary
+
+Grab the latest version from here:
+
+```bash
+https://github.com/senorprogrammer/wtf/releases
+```
+
+expand it, and `cd` into the resulting directory. Then run:
+
+```bash
+./wtf
+```
+
+and that should also do it.
