 The Software Working Group is working on physics and detector
 simulations that enable a quantitative assessment of the measurement
 capabilities of the EIC detector(s) and their physics impact for the
 Yellow Report Initiative. The common simulation tools and workflow
 environment being set up by the working group allow the EICUG to
 pursue the Yellow Report studies in a manner that is accessible,
 consistent, and reproducible.

 ### Eic-smear {#eicsmear}
 
 The master branch of [eic-smear](https://github.com/eic/eic-smear)
 is now updated to version 1.1.2, and that of [eicsmeardetetors](https://github.com/eic/eicsmeardetetors)
 to version 1.0.1. The changes are mostly incremental/experimental, but it is recommended all users update their local installations.
 
 eic-smear:
 * improved RAPGAP support;
 * fixed support for muons;
 * improved support for less common compilers as well as installation instructions.
 
 eicsmeardetectors:
 * We introduced a new genre of semi-official scripts, dubbed "WG additions".
 These are based on the official detector matrix but have added features agreed-upon within a PWG or DWG. Currently, these are:
    * ```MatrixDetector_0_1_FF```, which includes a rough parameterization of far forward detectors, and
    * ```MatrixDetector_0_1_TOF```, which is only a starting point for on-going development with the PID working group (do not use it yet; it is a preview which probably shouldn't be in the master branch).
 * Note that all official and semi-official scripts have been updated to support muons.
 * Further work is on-going to support calorimetry granularity for various projective and non-projective concepts.
 
 We hope to finalize work on PID and granularity on the same time scale as the upcoming release of detector matrix 0.2.
 
 Finally, extra thanks go out to a large group of volunteers from EIC India that is working hard to add QA, testing, and validation capabilities into eic-smear!
 
 ##### Recap: How to run eic-smear using cvmfs
 This package as well as a large suite of Monte Carlo generators and tools can be used the same way as detailed in the [fun4all section](#cvmfs), only changing the setup to
 ```
 singularity shell -B /cvmfs:/cvmfs /cvmfs/eic.opensciencegrid.org/singularity/rhic_sl7_ext.simg
 setenv EIC_LEVEL dev
 source /cvmfs/eic.opensciencegrid.org/x8664_sl7/MCEG/releases/etc/eic_bash.sh
 ```
 All packages are then under ```$EICDIRECTORY```.
 
 
 ### Fun4All {#fun4all}
 ##### TPC Endcap included
 For our TPC based simulations we now have a detailed endcap based on the sPHENIX design. This will enable studies how the TPC support material will affect especially the electron identification in the forward hemisphere. The endcap is configurable so it can serve as a basis to develop detailed TPC endcap designs for an eic detector. The endcap is by default disabled in the EIC detector based on the Babar magnet but can be enabled in the [macro](https://github.com/eic/fun4all_macros/blob/master/detectors/EICDetector/Fun4All_G4_EICDetector.C) (set Enable::TPC_ENDCAP = true in line 215).

 #### Recap: How to run Fun4All
 As a prerequisite you need to be able to run a singularity container on you local host. We have instructions to install a Ubuntu VM for [windows](https://github.com/eic/Singularity/blob/master/VirtualBox.md) and [macOS](https://github.com/eic/Singularity/blob/master/OSX_installationguide.md)
 ##### Using a local download of the libraries:
 We  provide a [script](https://github.com/eic/Singularity/blob/master/updatebuild.sh) which downloads and installs the needed libraries on your local host. This will give you a working envrionment where you can run simulations but also compile every package and develop new ones.
 ```
 git clone https://github.com/eic/Singularity
 cd Singularity
 ./updatebuild.sh
 ```
 If you have an existing installation, running the updatebuild.sh will update your local installation with the most recent changes. Then issue the two commands which are printed out at the end.
 
 ##### Using cmvfs {#cvmfs}
 If you have cvmfs on your host (and an internet connection) - using cvmfs is the prefered way of running. It will give you access to multiple software builds and you do not have to keep it updated yourself. We do provide weekly archival builds if you want to use something stable. In this case you only have to start the singularity container which resides in cvmfs and source the setup script inside it.
 ```
 singularity shell -B /cvmfs:/cvmfs /cvmfs/eic.opensciencegrid.org/singularity/rhic_sl7_ext.simg
 source /cvmfs/eic.opensciencegrid.org/x8664_sl7/opt/fun4all/core/bin/eic_setup.sh -n
 ```
