+
+Fetching the profile from the server can be done many ways, the easiest is to use the convenience function *GravatarProfile.getProfile*:
+
+```swift
+import SwiftGravatar
+
+if let profile = try await GravatarProfile.getProfile(using: "[email protected]"), let entry = profile.entry.first {
+	print(entry.preferredUsername)
+	print(entry.profileUrl)
+
+	print(entry.thumbnailUrl)
+	print(entry.photos?.first?.value)
+} else {
+	print("We have a problem...")
+}
+```
+
+Code can also be retrieved by other methods and then decoded:
+
+```swift
+guard let url = URL(string: "https://en.gravatar.com/632d2f3abe7be4db174da5cb2760f0ae.json") else {
+	return XCTFail("Unable to parse Gravatar URL")
+}
+let (data, _) = try await URLSession.shared.data(from: url)
+let profile = try JSONDecoder().decode(GravatarProfile.self, from: data)
+```
+
+An easy converter from e-mail to Gravatar URL can be accessed as follows:
+
+```swift
+let myemailaddress = GravatarProfile.getProfileAddress(using: "[email protected]")
+// "https://en.gravatar.com/0bc83cb571cd1c50ba6f3e8a78ef1346.json"
+```
