Recola: Recursive Computation of 1-Loop Amplitudes
==================================================


*Last updated:* |today|

----

Introduction
------------

|recola| is a |fortran| computer program for the *automated generation* and
*numerical computation* of tree and one-loop amplitudes at *next-to-leading
order* (EW, QCD) in the Standard Model (SM) and Beyond the SM (BSM).

The following sections cover the installation and basic usage of the tools.

:ref:`recola`
    Currently two separately maintained versions exist:
    
    * |recola| is the original version (*a.k.a* Recola1) which is tailored for computations within the Standard Model in the 't Hooft--Feynman gauge.
    * |recola2| is the successor of |recola|, a generalized version for computations in the SM, for BSM theories and SMEFT.

    A list of releases and the release history can be found :ref:`here <recola>`.
      
:ref:`installation`
    This section describes the building and installation steps of |recola| and |recola2|. 

:ref:`quickstart`
    This section describes the first steps in using |recola| and |recola2| (requires the :ref:`installation <installation>`). We go through the example of using the demo files and setting up new demo files. 

:ref:`modelfiles`
    In |recola2| model files are linked to the |recola2| library. We describe the models and their configuration and compilations steps for a manual installation (not required when using the |recola2|-|collier| :ref:`installation <vone>`). 

:ref:`docs`
    We list all functions provided by the library accessible to the user.
    This section is still under construction.
