Issue #256: Existing repository text for hg (conservancy/kallithea)

[Karl Goetz]

New issue 256: Existing repository text for hg
https://bitbucket.org/conservancy/kallithea/issues/256/existing-repository-text-for-hg

Karl Goetz:

Hi,
The existing repository text says

```
    hg push http://kgoetz@kallithea:5000/Configuration-management
```

but that doesn't configure for future pushes
```
 hg push
abort: default repository not configured!
(see 'hg help config.paths')
```

I suggest that (like the git instructions) the hg instructions give information about setting up the remote permanently.
