+## Installation
+
+### Simple `pip` method
+
+Install the package with `pip install spip2md` (or `python -m pip install spip2md`
+if you don’t have pip installed).
+
+Assuming your `$PATH` contains your `pip` install directory, you can now run
+`spip2md` a normal command of the same name.
+
+### Traditional method
+
+Clone this git repo with command `git clone` and `cd` into the created directory.
+
+Either make sure you have the dependencies installed system-wide, or create a
+Python virtual-environment and install them inside.
+
+You can then run `spip2md` as a Python module with command `python -m spip2md`.
+Make sure to replace `spip2md` with a relative path to directory `spip2md` if you
+didn’t `cd` into this repository’s directory.
