-However, if you feel adventurous feedback and pull requests are greatly appreciated.

 Also, be aware that the features described here are the goal that this library is aiming
 for and, as of now, not all of them are implemented (but most of them are).
 The dependency management is done while the packaging and publishing are still at the beginning.

 ## Installation
 
+Poetry provides a custom installer that will install `poetry` isolated
+from the rest of your system by vendorizing its dependencies. This is the
+recommended way of installing `poetry`.
+
+```bash
+curl -sSL https://raw.githubusercontent.com/sdispater/poetry/master/get-poetry.py | python
+```
+
+Alternatively, you can download the `get-poetry.py` file and execute it separately.
+
+If you want to install prerelease versions, you can do so by passing `--preview` to `get-poetry.py`:
+
 ```bash
-pip install poetry
+python get-poetry.py --preview
 ```
 
+Similarly, if you want to install a specific version, you can use `--version`:
+
+```bash
+python get-poetry.py --version 0.7.0
+```
+
+Using `pip` to install `poetry` is also possible.
+    
+```bash
+pip install --user poetry
+``` 
+    
+Be aware, however, that it will also install poetry's dependencies
+which might cause conflicts.
