### Extracting new strings for translation
```bash
-flask fab babel-extract --target superset/translations --output
superset/translations/messages.pot --config superset/translations/babel.cfg -k
_ -k __ -k t -k tn -k tct
+pybabel extract -F superset/translations/babel.cfg -o
superset/translations/messages.pot -k _ -k __ -k t -k tn -k tct .
+```
+
+This will update the template file `superset/translations/messages.pot` with
current application strings.
+
+### Updating language files
+
+```bash
+ pybabel update -i superset/translations/messages.pot -d superset/translations
--ignore-obsolete
```
+This will update language files with the new extracted strings.
+
You can then translate the strings gathered in files located under
`superset/translation`, where there's one per language. You can use
[Poedit](https://poedit.net/features)
to translate the `po` file more conveniently.
There are some [tutorials in the
wiki](https://wiki.lxde.org/en/Translate_*.po_files_with_Poedit).
-For the translations to take effect:
+In the case of JS translation, we need to convert the PO file into a JSON
file, and we need the global download of the npm package po2json.
```bash
-# In the case of JS translation, we need to convert the PO file into a JSON
file, and we need the global download of the npm package po2json.
npm install -g po2json
-flask fab babel-compile --target superset/translations
-# Convert the en PO file into a JSON file
-po2json -d superset -f jed1.x superset/translations/en/LC_MESSAGES/messages.po
superset/translations/en/LC_MESSAGES/messages.json
+```
+
+To convert all PO files to formatted JSON files you can use the `po2json.sh`
script.
+
+```bash
+./superset/translations/po2json.sh
