-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.
 
+The project used to be called "Zenith". Many of the commands and code comments
+still refer to "zenith", but we are in the process of renaming things.
+
 ## 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.
+[Join the waitlist](https://neon.tech/) for our free tier to receive your serverless postgres instance. Then connect to it with your preferred postgres client (psql, dbeaver, etc) or use the online SQL editor.
 
 Alternatively, compile and run the project [locally](#running-local-installation).
 
 ## Architecture overview
 
-A Neon installation consists of compute nodes and the Neon storage engine. Compute nodes are stateless PostgreSQL nodes backed by the Neon storage engine.
+A Neon installation consists of compute nodes and a 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.
-
-See developer documentation in [SUMMARY.md](/docs/SUMMARY.md) for more information.
+- Pageserver. Scalable storage backend for the compute nodes.
+- WAL service. The service receives WAL from the compute node and ensures that it is stored durably.
 
+Pageserver consists of:
+- Repository - Neon storage implementation.
+- WAL receiver - service that receives WAL from WAL service and stores it in the repository.
+- Page service - service that communicates with compute nodes and responds with pages from the repository.
+- WAL redo - service that builds pages from base images and WAL records on Page service request

-
-The project uses [rust toolchain file](./rust-toolchain.toml) to define the version it's built with in CI for testing and local builds.
-
-This file is automatically picked up by [`rustup`](https://rust-lang.github.io/rustup/overrides.html#the-toolchain-file) that installs (if absent) and uses the toolchain version pinned in the file.
-
-rustup users who want to build with another toolchain can use the [`rustup override`](https://rust-lang.github.io/rustup/overrides.html#directory-overrides) command to set a specific toolchain for the project's directory.

-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).
 
 ```sh
 git clone --recursive https://github.com/neondatabase/neon.git
-
-CARGO_BUILD_FLAGS="--features=testing" make
-
+make # builds also postgres and installs it to ./tmp_install
 ./scripts/pytest
 ```
 
-By default, this runs both debug and release modes, and all supported postgres versions. When
-testing locally, it is convenient to run just one set of permutations, like this:
-
-```sh
-DEFAULT_PG_VERSION=16 BUILD_TYPE=release ./scripts/pytest
-```
-
-## 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!
