-Alternatively, you can download the `get-poetry.py` file and execute it separately.
+!!! note
 
-If you want to install prerelease versions, you can do so by passing `--preview` to `get-poetry.py`:
+    You only need to install Poetry once. It will automatically pick up the current
+    Python version and use it to [create virtualenvs](/docs/basic-usage/#poetry-and-virtualenvs) accordingly.
 
-```bash
-python get-poetry.py --preview
-```
+The installer installs the `poetry` tool to Poetry's `bin` directory.
+On Unix it is located at `$HOME/.poetry/bin` and on Windows at `%USERPROFILE%\.poetry\bin`.
 
-Similarly, if you want to install a specific version, you can use `--version`:
+This directory will be in your `$PATH` environment variable,
+which means you can run them from the shell without further configuration.
+Open a new shell and type the following:
 
 ```bash
-python get-poetry.py --version 0.7.0
+poetry --version
 ```
 
+If you see something like `Poetry 0.11.4` then you are ready to use Poetry.
+If you decide Poetry isn't your thing, you can completely remove it from your system
+by running the installer again with the `--uninstall` option.

+Make sure your installed version of `pipsi` is at least version `0.10`,
