+# Contribution Guide - How to Setup Environment
+
+# WARNING - 18 Apr 2020 - THIS DOES NOT WORK YET!
+
+Whilst using Diagrams is easy and some folks will find setting up and extending Diagrams easy - for others with Python, Bash and Go dependancies it is harder...
+
+So a worked guide to setting up a VM with linux so you can contribute to Diagrams.
+
+Disclosure: This was written using ubuntu 18.04 on Azure. 
+
+## VM
+Easiest and cleanest way is to boot a new Linux VM on your cloud provide of choice. 
+* 16 GB HDD is more than enough
+* 2 GB Ram is more than enough 
+
+## Required Software
+
+To contribute to Diagrams you will need the required software (all installed from command prompt):
+
+* Python 2.7.x (comes pre-installed)
+
+* pip (to make your life easier)
+ ```shell
+    sudo apt update
+    sudo apt install python-pip
+```
+* Git
+ ```shell
+    sudo apt install git
+```
+* Go 
+    * Security warning (hence --classic) and hence why use VM
+ ```shell   
+    sudo snap install go --classic
+```
+
+
+## Requirements as per Contributing page
+* Round
+```shell
+    go get github.com/mingrammer/round
+    sudo cp go/bin/round /bin
+```
+
+* Inkscape
+ ```shell
+    sudo apt install inkscape
+```
+* Convert
+ ```shell
+    pip install convert
+``` 
+
+## Grab the Diagrams Code
+ ```shell
+   git clone https://github.com/mingrammer/diagrams.git
+``` 
+## To Run the Build
+ ```shell
+   cd diagrams
+    ./autogen.sh
+``` 
+
+# Known Issues
+When trying to run the build - which is needed to be able to be done before being able to contribute - autogen.sh causes:
+
+```shell
+....../diagrams$ ./autogen.sh
+converting the svg to png using inkscape for provider 'onprem'
+Traceback (most recent call last):
+  File "/usr/lib/python2.7/runpy.py", line 163, in _run_module_as_main
+    mod_name, _Error)
+  File "/usr/lib/python2.7/runpy.py", line 102, in _get_module_details
+    loader = get_loader(mod_name)
+  File "/usr/lib/python2.7/pkgutil.py", line 462, in get_loader
+    return find_loader(fullname)
+  File "/usr/lib/python2.7/pkgutil.py", line 472, in find_loader
+    for importer in iter_importers(fullname):
+  File "/usr/lib/python2.7/pkgutil.py", line 428, in iter_importers
+    __import__(pkg)
+  File "scripts/__init__.py", line 7
+    def app_root_dir(pvd: str) -> str:
+                        ^
+SyntaxError: invalid syntax
+```
+Hence we need to understand the dependancy which is missing to be able to contribute
+
+## Comment
+autogen.sh 
+* is using bash which is installed
+* The 'app_root_dir="diagrams"' does run 
+* The checks for round, inkscape and convert all pass
+
+But its failing as per error message above - which is beyond by Google-foo... (Or my Python knowledge which is not the greatest :-) 
+
+# TO DO
+* Add how to run modified code locally
