-## How to use
+## Install
 
-### As a subpackage
+### pip
 
-```python
-from pyParallelRunAndWrite import parallelRunAndWrite as prw
-# The following dependencies are only useful for testFunc
-import os
-from time import sleep
-from random import randint
-
-def testFunc(arg):
-    ret=str(arg)+str(os.getpid())
-    sleep(randint(2,5))
-    if(randint(0,100)%2 ==0):
-        raise Exception("COUCOU"+ret)
-    return ret
-
-prw.parallelRunAndWrite(testFunc, range(5), "testplop",  numProc=2, errFileName="errors")
+```bash
+pip3 install git+https://gitlab.tetras-libre.fr/tetras-libre/pyParallelRunAndWrite@master#egg=pyParallelRunAndWrite
 ```
 
-### By installing it
+### For developpement
 
 ```bash
+git clone https://gitlab.tetras-libre.fr/tetras-libre/pyParallelRunAndWrite
 pip3 install -e .
 ```
 
-Then :
+### As a dependency in your setup.py
+
+```python
+from setuptools.command.install import install
+from setuptools.command.develop import develop
+from setuptools import setup, find_packages
+import pip
+
+...
+
+gitDeps = [
+'git+https://gitlab.tetras-libre.fr/tetras-libre/pyParallelRunAndWrite@master#egg=pyParallelRunAndWrite',
+    ]

+def customRun(command_subclass):
+    orig_run = command_subclass.run
+
+    def modified_run(self):
+        for dep in gitDeps:
+            pip.main(['install', dep])
+
+        orig_run(self)
+
+    command_subclass.run = modified_run
