Hello @rumeysa_COSKUN, and welcome to the forum!
@wakocima acted kindly against Missooni and posted their shop-link, probably unfortunately for you was that the link to these brush-sets were not given but that to the shop.
So, you need to go here to get those sets:
Krita Brush Pack V1
Krita Brush Pack V2
And now follow this step-by-step-description to download the bundles:
Free things on ko-fi are easy to get, on the brush-set page you click here:
On the next page, you have to enter your email-address 1 and your name 2 in the corresponding fields. Then click on the blue button 3
“Checkout Now”.
This will show you the following page where you click on “View Content”:
Now you’ll be taken to the last step where you simply have to click on download:
In case you don’t know how to install a bundle in Krita:
A bundle is installed in Krita via the menu ‘‘Settings’’ >> ‘‘Manage Resource Libraries…’’ and in the opening dialog you have to click the button + Import in the next dialog browse to the downloaded bundle, select it and confirm the selection. Now Krita imports that bundle, and you can use its content, so the brushes in case of this bundle.
In case this BUNDLE comes in an archive-file, like ZIP or RAR for instance, then you have to unpack the archive to get the BUNDLE-File it contains, then you can proceed as described above.
