 The [](quapy.method.composable) module allows the composition of quantification methods from loss functions and feature transformations. Any composed method solves a linear system of equations by minimizing the loss after transforming the data. Methods of this kind include ACC, PACC, HDx, HDy, and many other well-known methods, as well as an unlimited number of re-combinations of their building blocks.
 
+### Installation
+
+```sh
+pip install --upgrade pip setuptools wheel
+pip install "jax[cpu]"
+pip install quapy[composable]
+```
+
+### Basics
+
 The composition of a method is implemented through the [](quapy.method.composable.ComposableQuantifier) class. Its documentation also features an example to get you started in composing your own methods.

 To implement your own loss functions and feature representations, follow the corresponding manual of the [qunfold package](https://github.com/mirkobunse/qunfold), which provides the back-end of QuaPy's composable module.
