-If you encounter errors during setting up the initial tenant, it's best to stop everything (`cargo neon stop`) and remove the `.neon` directory. Then fix the problems, and start the setup again.

 ## Running tests
 
-### Rust unit tests
-
-We are using [`cargo-nextest`](https://nexte.st/) to run the tests in Github Workflows.
-Some crates do not support running plain `cargo test` anymore, prefer `cargo nextest run` instead.
-You can install `cargo-nextest` with `cargo install cargo-nextest`.

-## Cleanup
-
-For cleaning up the source tree from build artifacts, run `make clean` in the source directory.
-
-For removing every artifact from build and configure steps, run `make distclean`, and also consider removing the cargo binaries in the `target` directory, as well as the database in the `.neon` directory. Note that removing the `.neon` directory will remove your database, with all data in it. You have been warned!

-# Control Plane and Neon Local
-
-This crate contains tools to start a Neon development environment locally. This utility can be used with the `cargo neon` command.
-
-## Example: Start with Postgres 16
-
-To create and start a local development environment with Postgres 16, you will need to provide `--pg-version` flag to 3 of the start-up commands.
-
-```shell
-cargo neon init --pg-version 16
-cargo neon start
-cargo neon tenant create --set-default --pg-version 16
-cargo neon endpoint create main --pg-version 16
-cargo neon endpoint start main
-```
-
-## Example: Create Test User and Database
-
-By default, `cargo neon` starts an endpoint with `cloud_admin` and `postgres` database. If you want to have a role and a database similar to what we have on the cloud service, you can do it with the following commands when starting an endpoint.
-
-```shell
-cargo neon endpoint create main --pg-version 16 --update-catalog true
-cargo neon endpoint start main --create-test-user true
-```
-
-The first command creates `neon_superuser` and necessary roles. The second command creates `test` user and `neondb` database. You will see a connection string that connects you to the test user after running the second command.

-/// ## What do we store?
-///
-/// The storage controller service does not store most of its state durably.
-///
-/// The essential things to store durably are:
-/// - generation numbers, as these must always advance monotonically to ensure data safety.
-/// - Tenant's PlacementPolicy and TenantConfig, as the source of truth for these is something external.
-/// - Node's scheduling policies, as the source of truth for these is something external.
-///
-/// Other things we store durably as an implementation detail:
-/// - Node's host/port: this could be avoided it we made nodes emit a self-registering heartbeat,
-///   but it is operationally simpler to make this service the authority for which nodes
-///   it talks to.
-///
-/// ## Performance/efficiency
-///
-/// The storage controller service does not go via the database for most things: there are
-/// a couple of places where we must, and where efficiency matters:
-/// - Incrementing generation numbers: the Reconciler has to wait for this to complete
-///   before it can attach a tenant, so this acts as a bound on how fast things like
-///   failover can happen.
-/// - Pageserver re-attach: we will increment many shards' generations when this happens,
-///   so it is important to avoid e.g. issuing O(N) queries.
-///
-/// Database calls relating to nodes have low performance requirements, as they are very rarely
-/// updated, and reads of nodes are always from memory, not the database.  We only require that
-/// we can UPDATE a node's scheduling mode reasonably quickly to mark a bad node offline.
