## Installing forks
### For all of them.
You should install [pip] (usually python-pip and python3-pip in
repositories) and [git].
Windows users should also install [pip] and [msysgit] and in [msysgit]
select to run **unix tools in PATH**.
Note: pip is included with Python =< 3.4! Python 3 is only supported by
Limnoria.
For **rootless installation**, please see
[Limnoria's documentation.](http://supybot.aperio.fr/doc/use/install.html#local-installation) which you should be able to modify to install stock
Supybot or gribble with the information below.
If you don't have sudo, please simply remove it from beginnings of lines
and run the commands as root or Administrator.
[git]:http://git-scm.com/
[pip]:http://pip.readthedocs.org/en/latest/reference/pythonpip_install.html
[msysgit]:https://msysgit.github.io/
### Supybot
**Not recommended as it's not actively developed.**
```
sudo python -m pip install git+https://github.com/supybot/supybot.git --upgrade
```
### gribble
Less actively developed than Limnoria and doesn't support Python 3.
```
sudo python -m pip install git+https://github.com/nanotube/supybot_fixes.git --upgrade
```
### Limnoria
At the time of writing, the most active Supybot fork which includes
embedded HTTPd for plugins needing it, supports other languages than
English and also runs with Python 3.
The first command installs requirements of Limnoria and the second
Limnoria itself. Only Limnoria has requirements.txt file at the moment.
```
sudo python3 -m pip install -r https://raw.githubusercontent.com/ProgVal/Limnoria/master/requirements.txt --upgrade
sudo python3 -m pip install git+https://github.com/ProgVal/Limnoria.git@master --upgrade
```
#### python3 -m pip
If you don't have pip for Python3 you can
```
curl -LO https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py
```
if `curl -LO` doesn't work, try replacing it with `wget`.
