 $ pip install randonautentropy
 ```
 
+### Installing Temporal
+
+The first time the `temporal.get` Python method or `rndo -t` command line option are called, a script attempts to automatically install the [TemporalLib](https://github.com/TheRandonauts/temporal) shell tool dependency in `/usr/local/bin`
+
+In case that fails you can install it yourself:
+
+```
+$ sudo apt install git build-essential
+$ git clone --depth 1 git@github.com:TheRandonauts/temporal.git
+$ cd temporal
+$ ./make.sh
+```
