-
-We have a sample pre-commit hook in `pre-commit.py`.
-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.
-
-If you want to skip the hook, run `git commit` with `--no-verify` option.

-# How to run a CI pipeline on Pull Requests from external contributors
-_An instruction for maintainers_
-
-## TL;DR:
-- Review the PR
-- If and only if it looks **safe** (i.e. it doesn't contain any malicious code which could expose secrets or harm the CI), then:
-    - Press the "Approve and run" button in GitHub UI
-    - Add the `approved-for-ci-run` label to the PR
-    - Currently draft PR will skip e2e test (only for internal contributors). After turning the PR 'Ready to Review' CI will trigger e2e test
-      - Add `run-e2e-tests-in-draft` label to run e2e test in draft PR (override above behaviour)
-      - The `approved-for-ci-run` workflow will add `run-e2e-tests-in-draft` automatically to run e2e test for external contributors
-
-Repeat all steps after any change to the PR.
-- When the changes are ready to get merged — merge the original PR (not the internal one)
-
-## Longer version:
-
-GitHub Actions triggered by the `pull_request` event don't share repository secrets with the forks (for security reasons).
-So, passing the CI pipeline on Pull Requests from external contributors is impossible.
-
-We're using the following approach to make it work:
-- After the review, assign the `approved-for-ci-run` label to the PR if changes look safe
-- A GitHub Action will create an internal branch and a new PR with the same changes (for example, for a PR `#1234`, it'll be a branch `ci-run/pr-1234`)
-- Because the PR is created from the internal branch, it is able to access repository secrets (that's why it's crucial to make sure that the PR doesn't contain any malicious code that could expose our secrets or intentionally harm the CI)
-- The label gets removed automatically, so to run CI again with new changes, the label should be added again (after the review)
-
-For details see [`approved-for-ci-run.yml`](.github/workflows/approved-for-ci-run.yml)
-
-## How do I make build-tools image "pinned"
-
-It's possible to update the `pinned` tag of the `build-tools` image using the `pin-build-tools-image.yml` workflow.
-
-```bash
-gh workflow -R neondatabase/neon run pin-build-tools-image.yml \
-            -f from-tag=cc98d9b00d670f182c507ae3783342bd7e64c31e

 # 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/github) 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.

-
-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.

 ## Error message style

-
 PostgreSQL has a style guide for writing error messages:
 
 https://www.postgresql.org/docs/current/error-style-guide.html
 
 Follow that guide when writing error messages in the PostgreSQL
-extensions.
+extension. We don't follow it strictly in the pageserver and
-
+safekeeper, but the advice in the PostgreSQL style guide is generally
-### Neon Rust code
+good, and you can't go wrong by following it.
-
-#### Anyhow Context
-
-When adding anyhow `context()`, use form `present-tense-verb+action`.
-
-Example:
-- Bad: `file.metadata().context("could not get file metadata")?;`
-- Good: `file.metadata().context("get file metadata")?;`
-
-#### Logging Errors
-
-When logging any error `e`, use `could not {e:#}` or `failed to {e:#}`.
-
-If `e` is an `anyhow` error and you want to log the backtrace that it contains,
-use `{e:?}` instead of `{e:#}`.
-
-#### Rationale
-
-The `{:#}` ("alternate Display") of an `anyhow` error chain is concatenation fo the contexts, using `: `.
-
-For example, the following Rust code will result in output
-```
-ERROR  failed to list users: load users from server: parse response: invalid json
-```
-
-This is more concise / less noisy than what happens if you do `.context("could not ...")?` at each level, i.e.:
-
-```
