clean up

Noticed this while debugging a test failure in #8673 which only occurs
with real S3 instead of mock S3: if you authenticate to S3 via
`AWS_PROFILE`, then it requires the `HOME` env var to be set so that it
can read inside the `~/.aws` directory.

The scrubber abstraction `StorageScrubber::scrubber_cli` in
`neon_fixtures.py` would otherwise not work. My earlier PR #6556 has
done similar things for the `neon_local` wrapper.

You can try:

```
aws sso login --profile dev
export ENABLE_REAL_S3_REMOTE_STORAGE=y REMOTE_STORAGE_S3_BUCKET=neon-github-ci-tests REMOTE_STORAGE_S3_REGION=eu-central-1 AWS_PROFILE=dev
RUST_BACKTRACE=1 BUILD_TYPE=debug DEFAULT_PG_VERSION=16 ./scripts/pytest -vv --tb=short -k test_scrubber_tenant_snapshot
```

before and after this patch: this patch fixes it.

+To set it up, run:
+
+```bash
+ln -s ../../pre-commit.py .git/hooks/pre-commit
+```
+
+This will run following checks on staged files before each commit:
+- `rustfmt`
+- checks for Python files, see [obligatory checks](/docs/sourcetree.md#obligatory-checks).
+
+There is also a separate script `./run_clippy.sh` that runs `cargo clippy` on the whole project
+and `./scripts/reformat` that runs all formatting tools to ensure the project is up to date.

 # Neon
 
 Neon is a serverless open-source alternative to AWS Aurora Postgres. It separates storage and compute and substitutes the PostgreSQL storage layer by redistributing data across a cluster of nodes.
 
 ## Quick start
-Try the [Neon Free Tier](https://neon.tech/docs/introduction/technical-preview-free-tier/) to create a serverless Postgres instance. Then connect to it with your preferred Postgres client (psql, dbeaver, etc) or use the online [SQL Editor](https://neon.tech/docs/get-started-with-neon/query-with-neon-sql-editor/). See [Connect from any application](https://neon.tech/docs/connect/connect-from-any-app/) for connection instructions.

 A Neon installation consists of compute nodes and the Neon storage engine. Compute nodes are stateless PostgreSQL nodes backed by the Neon storage engine.
 
 The Neon storage engine consists of two major components:
-- Pageserver. Scalable storage backend for the compute nodes.
-- Safekeepers. The safekeepers form a redundant WAL service that received WAL from the compute node, and stores it durably until it has been processed by the pageserver and uploaded to cloud storage.

+More advanced usages can be found at [Control Plane and Neon Local](./control_plane/README.md).
+
+#### Handling build failures
+
+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`.
+
+### Integration tests
+
 Ensure your dependencies are installed as described [here](https://github.com/neondatabase/neon#dependency-installation-notes).

+## Flamegraphs
+
+You may find yourself in need of flamegraphs for software in this repository.
+You can use [`flamegraph-rs`](https://github.com/flamegraph-rs/flamegraph) or the original [`flamegraph.pl`](https://github.com/brendangregg/FlameGraph). Your choice!
+
+>[!IMPORTANT]
+> If you're using `lld` or `mold`, you need the `--no-rosegment` linker argument.
+> It's a [general thing with Rust / lld / mold](https://crbug.com/919499#c16), not specific to this repository.
+> See [this PR for further instructions](https://github.com/neondatabase/neon/pull/6764).
+
+## 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!

+        // than available RAM.
+        //

+# 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.
