Hey @mhduiy - I've reviewed your changes - here's some feedback:

• Several image links use an empty alt tag (![](…)) after your changes—consider adding descriptive alt text for those to keep accessibility consistent.
• I see p_notification.png added to assets but not referenced anywhere in the docs—please verify and integrate it where it’s meant to appear.
• To prevent future casing or syntax drift, you could add a CI check or simple script that enforces the standardized image reference format and filename casing across all markdown files.
