 ## Translating
 
 Translation is managed through [Transifex](https://www.transifex.com/yohanboniface/umap/dashboard/).
+
+## Bugs Triaging
+
+You are very welcome to help us triaging [uMap issues](https://github.com/umap-project/umap/issues).
+
+* Help other users by answering questions
+* Give your point of view in discussions
+* And so on...
+
+## Development on Ubuntu
+
+### Environnement setup
+
+Follow the procedure [Ubuntu from scratch](ubuntu.md)
+
+But instead using folders /etc/umap, you can create a ~/.umap folder.
+This folder will contain the umap.conf file.
+
+And for folder /srv/umap, you can create a ~/umap folder (We will remove this folder later)
+
+You will have to set an env var, we will set it in your .bashrc:
+
+    nano ~/.bashrc
+
+Add the following at the end of file:
+
+```
+# uMap
+export UMAP_SETTINGS=~/.umap/umap.conf
+```
+
+Then refresh your terminal
+
+    source ~/.bashrc
+
+Run your local uMap and check that it is working properly.
+
+### Hacking on the code
+
+Create a workspace folder ~/wk and go into it.
+
+"git clone" the main repository and go in the umap folder
+
+Several commands, needs you to be in a virtualenv:
+
+    virtualenv ~/wk/umap/venv --python=/usr/bin/python3.6
+    source /srv/umap/venv/bin/activate
+
+Now, command "umap" will be available
+
+*Note: if you close your terminal, you will need to re-run command:*
+
+    source /srv/umap/venv/bin/activate
+
+To test your code, you will add to install umap from your git folder. Go to ~/wk/umap and run:
+
+    pip install -e .
+    # or pip install -e ~/wk/umap
+
+This command, will check dependencies and install uMap from sources inside folder.
+
+To start your local uMap:
+
+    umap runserver 0.0.0.0:8000
+
+### Update translations
+
+Install needed tools:
+
+    apt install gettext transifex-client
+
+Pull the translations from transifex website:
+
+    tx pull -f
+
+Then you will need to update binary files with command:
+    make compilemessages
+
+Done. You can now review and commit modified/added files.
