+SasView is being reworked, in the ESS_GUI git branch, to use PyQT 5.0 for the GUI. Please note that this branch uses '''exclusively Python 3'''. There is no need to install Anaconda again, though, because the environment YAML file (see below) will ensure that Python 3 is installed.
 
+Using Git Bash, {{{cd}}} to your sasview directory and run:
+
+{{{
 git checkout ESS_GUI
-
-''Look for ''sasview/build_tools/conda_py3_qt5_env.yml'', open it in an editor, save it somewhere else '''outside '''of git control, '''remove''' in the pip section the lines for ''sasview ''and ''sasmodels'', then '''add '''there '''''- tinycc==1.1 '''''the compiler for the models.''
+}}}
+Look for {{{sasview/build_tools/conda_py3_qt5_env.yml}}}, open it in an editor, save it somewhere else '''outside''' of git control, '''remove''' in the pip section the lines for {{{sasview}}} and {{{sasmodels}}}, then '''add''' there: {{{- tinycc==1.1}}} (the compiler for the models).
 
 ''[Note - if later whilst running sasview you have problems with models not compiling or loading, close sasview, delete the contents of the directory users/your-user-name/sasmodels/compiled_models, then re-start, which will force re-compilation using the current compiler.]''
 
+In an Anaconda prompt (or equivalently in Git Bash, if your Anaconda installation is in your $PATH), run:
+
+{{{
 conda env create -f=/path-to-your-new-yml-file/conda_py3_qt5_env_new.yml
+conda activate qt5
+}}}
 
-source activate qt5
-
-cd src/sas/qtgui
-
-python convertUI.py
-
-cd ../../..
-
-python run.py
+You can now run {{{python run.py}}} as usual to start the application.
 
 ''If run.py gives an error from line 1140 in readCategoryInfo, you likely have the old version of the categories file. Delete the file serial_cat.json from your user directory  ( c:/users/username/.sasview in Windows) and then run the latest *release* version of sasview. This will automatically generate the correct categories.json file.''
 
-''Other useful conda commands:''
+''If qt5 sasview does not run the first time through, try going back to the normal sasview master ({{{git checkout master}}}), then repeat the steps above once more (trust me it may then work!). Piotr and others will be making this easier in the future.''
 
-conda info --envs      ''will show that you now have both sasview and qt5 environments.''
+=== Other useful conda commands ===
 
-conda env remove --name qt5''  ''
+{{{conda info --envs}}}
+This will show that you now have both sasview and qt5 environments.
 
-''will remove the qt5 environment, though the files involved seem to stay on your hard drive so a new ''conda env create ''is much faster than the first time.''
+----
 
-''if something fails part way through creating an environment, such as not removing the pip install for sasview & sasmodels, then "update" will be faster e.g.''
+{{{conda env remove --name qt5}}}
+This will remove the qt5 environment, though the files involved seem to stay on your hard drive so a new {{{conda env create}}} is much faster than the first time.
 
-conda env update -f=/path to your new yml file/conda_py3_qt5_env_new.yml --name qt5
