How do I install an extension directly from git?

Question

Now that I have found my extension directory, is installing an experimental (or developmental) extension as simple as cloning it into there? eg:

# find extension directory
DIR=$(cv ev --out=pretty 'return (new CRM_Extension_System())->getDefaultContainer()->baseDir')
# change to extension directory
cd $DIR
# clone repo
git clone [email protected]:civicrm/api4.git
# flush cache
cv flush
# enable 
cv ext:enable api4

(obviously some git remote voodoo required still but just wanting to confirm that this is the basics)

Answer 1

Yes, that's all you need to do! In my experience, flushing the cache is unnecessary though.
