 Setting up directories
 ----------------------
-- create a directory in which you also have the loser/, expoweb/ and drawings/ repositories
+- create an 'expo' directory in which you also have the loser/, expoweb/ and drawings/ repositories
 - git clone (see below) the current latest troggle from the 'python3' git branch into 
   a folder called 'troggle'
 - all the 4 repos should now be siblings, and also siblings with expofiles/ and expowebcache/
 - if you have those repos elsewhere, set up symlinks in the directory above troggle
   so that troggle thinks they are siblings

 Python3, Django, and Database setup
 -----------------------------------
 We are now using Django 2.2.19 
-
-Read this: https://docs.djangoproject.com/en/3.0/topics/install/
-
 We are installing with python3.7
-Also : https://linuxize.com/post/how-to-install-pip-on-ubuntu-20.04/ ]
 
 Install Django using pip, not with apt, on your test system.
-You will also definitely need sqlite3 even if you are planning to use another
-database. Sqlite3 is used by the test harness system.
-Your Linux installation almost certainly already includes python3 and pip3 but
-in case it doesn't install those.
-You also need survex - which installs a shedload of other packages.
 
-$ sudo apt update
-$ sudo apt dist-upgrade
-$ sudo apt install python3
-$ sudo apt install python3-pip
-$ sudo apt install sqlite3 sqlite3-doc
-$ cd /usr/bin
-$ sudo ln -s python3 python
-$ sudo ln -s pip3 pip
-$ sudo apt install survex
+[installation instructions removed - now in http://expo.survex.com/handbook/troggle/troglaptop.html ]
 
-Now install django etc.
-$ cd [troggle]
-$ sudo pip install -r requirements.txt
+[venv description removed - read it in http://expo.survex.com/handbook/troggle/troglaptop.html ]
 
-where requirements.txt is:
-confusable-homoglyphs==3.2.0
-Django==2.2
-docutils==0.14
-gunicorn==20.1.0
-Pillow==5.4.1
-pytz==2019.1
-sqlparse==0.2.4
-Unidecode==1.0.23
-
-These minor things are as-standard on Debian Buster (10).
-
-if you don't use sudo it will install them all in ~/.local/
-and so will only be available for you, not everyone; and
-the paths won't work to find troggle properly.
-
-Pillow is an image handling package used to make
-the prospecting map. tinymce is the wysiwyg in-browser
-editor (disabled pending reinstatement)
-
-$ pip list -o
-will list all the pip python packages installed.
-
-[NB we should test whether later verisons of tinymce work.]
-
-venv option
------------
-Or use a python3 virtual environment: (python3.5 or later)
-$ cd troggle
-$ cd ..
-$ python3.7 -m venv pyth37d2
-(creates folder with virtual env)
-$ cd pyth37d2
-$ source bin/activate
-(now install everything )
-$ pip install -r requirements.txt
