Installing Eclipse for Django/Python

Install Eclipse from the repos.  I’m just using Synaptic (installing on Mint), search for Eclipse and tick it (and agree to install the bunch of dependencies)

Once installed, open Eclipse.  Following the instructions here,

Click Help > Install New Software

Click Add

In the name field, enter Pydev and Pydev Extensions. 
In location, enter http://pydev.org/updates 

It should locate the software - Install Pydev for Eclipse (Pydev Django Templates Editor wouldn’t install because of a dependency - I’ve forgotten about it and moved on)

A restart, and you’re done.
