Damn 12 links are dead skull

Looks like scheduling the Action to run every 15 days was a good call right? 🤣

whosoever takes this up,

• If you are not able to find the original source of URLs, check https://web.archive.org/. If the URLs are still not reachable then remove those resources from README
• apart from fixing 404 URLs, make sure to check for URLs whose status was not reported in the above table (like URLs that now have a new domain or redirect to something else, etc)

oh I might as well take this up 😆

[Jarmos-san]

@V3dantSh4rma if you're not interested in it let @HanakoK9 take it up (or you guys collaborate on it together)?

@HanakoK9 batao bhaiya, Dono help kare kya iss issue pe?

[V3dantSh4rma]

Alrighty, You can try getting the links from the number 10 to 20 and I will try getting the links from 1-10 No need to do it, I did it

I found an issue. The "4"th number of that table is of udemy, and it's paid. If anyone has the free resources of it. Send it here. Also take a look at the 5th website, Found it on wayback machine and the link is broken. Take a look at this too and do let me know Fixed

[V3dantSh4rma]

Also, the 6th website, 7th and 8th has a udemy link too. Don't know what should I do in here Fixed

[Jarmos-san]

Add a "paid" comment beside any resources which are locked behind a paywall. Here's an example:

Learn Japanese Level N5 (All 15 courses) (Paid)

Please spend some time and figure out the Removed Websites and Let me know it's source. If you guys are still not able to find it's alternative, That's okay too :)
