Contributing to the MDN platform with Python and Django

Hello I know python and django. I want to contribute to the code base using django but i am totally confused about it. Iv tried reaching out for many people but couldnt find any help. I visited the docs and whatcanidoformozilla site but one thing i found was to find a bug and learn to fix it. I a beginner and I dont understand any of it. Frankly its very confusing and overwhelming. I need some one to set me on the right path, guide me and teach me.

Just to be clear, are you talking about contributing to the MDN platform itself? The best place to get set with a local install of Kuma (the MDN platform) and start playing with it is:

https://kuma.readthedocs.io/en/latest/installation.html

Also see the kuma repo for more help:

This is what i get when i try to clone the repo using
git clone --recursive git@github.com:mozilla/kuma.git

The authenticity of host ‘github.com (192.30.253.112)’ can’t be established.

Are you sure you want to continue connecting (yes/no)? yes

Have you added an SSH key to your GitHub account:

?

This was my first thought on seeing that error message.

i ran git clone https://github.com/mozilla/kuma.git
insted of git clone --recursive git@github.com:mozilla/kuma.git
does this make any difference ?

i continued and docker was working well until

docker exec -i kuma_web_1 make localecompile
mkdir: cannot create directory 'build': Permission denied make: *** [compilejsi18n] Error 1
## Generating JavaScript translation catalogs ##
Makefile:53: recipe for target 'compilejsi18n' failed

now i made a SSH key and added it to my github account

i ran docker-compose up
and now it is running for an hour now
something like this
