<pre>

git clone https://gitlab.irap.omp.eu/epallier/pyros.git PYROS
68 5 Etienne Pallier
(or also : git clone git@gitlab.irap.omp.eu:epallier/pyros.git PYROS)

This creates a PYROS/ folder containing the project (with a .git/ subfolder for synchronization with the git repository)

73 48 Etienne Pallier
(
74 1 Etienne Pallier
_If you just wanted a static copy of the project (without synchronization), just remove the .git/ folder:_
75 1 Etienne Pallier
$ rm -r .git/
76 48 Etienne Pallier

Now, Pyros needs some dependencies that you have to install.
79 48 Etienne Pallier
For this, you can read the INSTALL document from PYROS/install/
80 48 Etienne Pallier
or go on reading this wiki page.

h3. Install a database server (only if necessary)
88 38 Etienne Pallier
89 50 Etienne Pallier
By default, Pyros uses Mysql, but this implies that you have to install the Mysql database server...
90 1 Etienne Pallier
91 40 Etienne Pallier
Thus, to make things easier, avoid Mysql installation by using Sqlite instead as the database server (which will need no installation at all) :
92 40 Etienne Pallier
93 44 Etienne Pallier
=> For this, just edit the file PYROS/src/pyros/settings.py and set MYSQL variable to False, and that's it. You can go to next section.
94 40 Etienne Pallier
95 44 Etienne Pallier
Now, if you really want to use Mysql (which is the default), you will need to install it (only if not already installed), so keep reading.
96 40 Etienne Pallier
97 44 Etienne Pallier
_(Skip this if you are using Sqlite instead of MySql)_
