+# TIPS - Transaction Inclusion Prioritization Stack
+
+## Overview
+TIPS is an experimental project to replace the p2p mempool with a collection of stateless servies to enable:
+
+- Higher throughput
+- Simulation of all transaction
+- Cost savings on hardware
+- Bundle support
+
+## Code Style & Standards
+- Do not add comments unless instructed
+- Put imports at the top of the file, never in functions
+- Use `just fix` to fix formatting and warnings
+- Run `just ci` to verify your changes
+- Add dependencies to the Cargo.toml in the root and reference them in the crate cargo files
+- Always use the latest dependency versions. Use https://crates.io/ to find dependency versions when adding new deps
+- For logging use the tracing crate with appropriate levels and structured logging
