This is not a hard rule: under special cirmstances branches can be useful.
They should not however be considered "routine".

+In each of these directories, **in the order listed**, track down the
`setup.py` file, then, as root (`sudo bash`), run the following:
* python3 setup.py develop
preferably with a link to a URL in the [bugtracker](https://bugs.libre-soc.org/)
with further details as to why the unit test should not be run.
+# Task management guidelines
+
+1. Create the task in appropriate "Product" section with appropriate
+ "Component" section. Most code tasks generally use "Libre-SOC's
+ first SOC".
+2. Fill in "Depends on" and "Blocks" section whenever appropriate.
+ Also add as many related ("See Also") links to other bugreports
+ as possible. bugreports are never isolated.
+3. Choose the correct task for a budget allocation. Usually the parent
+ task is used.
+4. Choose the correct NLnet milestone. The best practice is to check
+ the parent task for a correct milestone.
+5. Assign the budget to the task in `"USER=SUM"` form, where "USER"
+ corresponds to your username and "SUM" corresponds to the actual
+ budget in EUR. There may be multiple users.
+6. When the task is completed, you can begin writing an RFP.
+ **DO NOT submit it without explicit authorisation and review**.
+ Leave out your bank and personal address details if you prefer
+ when sending to the Team Manager for review.
+7. Once the RFP is written, notify the Team Manager and obtain their
+ explicit approval to send it.
+8. Once approval is received and the RFP sent, update the `"USER=SUM"`
+ field to include the submitted date:
+ `"USER={amount=SUM, submitted=SDATE}"`. The SDATE is entered in
+ `YYYY-MM-DD` form.
+9. Once the task is paid, again notify the Team Manager (IRC is fine),
+ and update `"USER={amount=SUM, submitted=SDATE}"`
+ to `"USER={amount=SUM, submitted=SDATE, paid=PDATE}"`. The PDATE is
+ entered in `YYYY-MM-DD` form, too.
+
+Throughout all of this you should be using budget-sync to check the
+database consistency
