`fun add(sessions: `[`List`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-list/index.html)`<`[`Session`](../-session/index.md)`>): `[`Unit`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) [(source)](https://github.com/mozilla-mobile/android-components/blob/master/components/browser/session/src/main/java/mozilla/components/browser/session/SessionManager.kt#L139)

for every added [Session](../-session/index.md).
