Given how closely related the server development with Rama is to Axum you can probably save a lot of time by copying axum's directory at https://github.com/sharkbench/sharkbench/tree/main/benchmark/web/rust/axum-0.7-rust-1.74 and swap out axum with rama.

For now you can just depend on rama 0.2.0-alpha.6 As such the name of the directory would probably be rama-0.2-alpha.6-rust-1.84. Not sure how happy they would be to move to rust-1.84 though as all others are on rust 1.74... Then again I don't see a good reason for staying behind either, so they might welcome upgrading the rust version as well.
