-# Zenith
+# Neon
 
-Zenith is an serverless open source alternative to AWS Aurora Postgres. It separates storage and compute and substitutes PostgreSQL storage layer by redistributes data across a cluster of nodes. 
+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.
+
+Alternatively, compile and run the project [locally](#running-local-installation).
 
 ## Architecture overview
 
-A Zenith installation consists of Compute nodes and Storage engine.
+A Neon installation consists of compute nodes and the Neon storage engine. Compute nodes are stateless PostgreSQL nodes backed by the Neon storage engine.
 
-Compute nodes are stateless PostgreSQL nodes, backed by zenith storage.
+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.
 
-Zenith storage engine consists of two major components:
-- Pageserver. Scalable storage backend for compute nodes.
-- WAL service. The service that receives WAL from compute node and ensures that it is stored durably.
-
-Pageserver consists of:
-- Repository - Zenith 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.
+See developer documentation in [/docs/SUMMARY.md](/docs/SUMMARY.md) for more information.
 
 ## Running local installation
 
-1. Install build dependencies and other useful packages
 
-On Ubuntu or Debian this set of packages should be sufficient to build the code:
-```text
+#### Installing dependencies on Linux
+1. Install build dependencies and other applicable packages
+
+* On Ubuntu or Debian, this set of packages should be sufficient to build the code:
+```bash
 apt install build-essential libtool libreadline-dev zlib1g-dev flex bison libseccomp-dev \
-libssl-dev clang pkg-config libpq-dev
+libssl-dev clang pkg-config libpq-dev cmake postgresql-client protobuf-compiler
+```
+* On Fedora, these packages are needed:
+```bash
+dnf install flex bison readline-devel zlib-devel openssl-devel \
+  libseccomp-devel perl clang cmake postgresql postgresql-contrib protobuf-compiler \
+  protobuf-devel
 ```
 
-[Rust] 1.55 or later is also required.
+2. [Install Rust](https://www.rust-lang.org/tools/install)
+```
+# recommended approach from https://www.rust-lang.org/tools/install
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+```
 
-To run the `psql` client, install the `postgresql-client` package or modify `PATH` and `LD_LIBRARY_PATH` to include `tmp_install/bin` and `tmp_install/lib`, respectively.
+#### Installing dependencies on OSX (12.3.1)
+1. Install XCode and dependencies
+```
+xcode-select --install
+brew install protobuf openssl flex bison
+```
+
+2. [Install Rust](https://www.rust-lang.org/tools/install)
+```
+# recommended approach from https://www.rust-lang.org/tools/install
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+```
+
+3. Install PostgreSQL Client
+```
+# from https://stackoverflow.com/questions/44654216/correct-way-to-install-psql-without-full-postgres-on-macos
+brew install libpq
+brew link --force libpq
+```
+
+#### Rustc version
+
+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 [`rustup override`](https://rust-lang.github.io/rustup/overrides.html#directory-overrides) command to set a specific toolchain for the project's directory.
+
+non-rustup users most probably are not getting the same toolchain automatically from the file, so are responsible to manually verify their toolchain matches the version in the file.
+Newer rustc versions most probably will work fine, yet older ones might not be supported due to some new features used by the project or the crates.
+
+#### Building on Linux
+
+1. Build neon and patched postgres
+```
+# Note: The path to the neon sources can not contain a space.
+
+git clone --recursive https://github.com/neondatabase/neon.git
+cd neon
+
+# The preferred and default is to make a debug build. This will create a
+# demonstrably slower build than a release build. For a release build,
+# use "BUILD_TYPE=release make -j`nproc`"
+
+make -j`nproc`
+```
+
+#### Building on OSX
+
+1. Build neon and patched postgres
+```
+# Note: The path to the neon sources can not contain a space.
+
+git clone --recursive https://github.com/neondatabase/neon.git
+cd neon
+
+# The preferred and default is to make a debug build. This will create a
+# demonstrably slower build than a release build. For a release build,
+# use "BUILD_TYPE=release make -j`sysctl -n hw.logicalcpu`"
+
+make -j`sysctl -n hw.logicalcpu`
+```
+
+#### Dependency installation notes
+To run the `psql` client, install the `postgresql-client` package or modify `PATH` and `LD_LIBRARY_PATH` to include `pg_install/bin` and `pg_install/lib`, respectively.
 
 To run the integration tests or Python scripts (not required to use the code), install
-Python (3.7 or higher), and install python3 packages using `pipenv install` in the project directory.
+Python (3.9 or higher), and install python3 packages using `./scripts/pysync` (requires [poetry](https://python-poetry.org/)) in the project directory.

 ## Running tests
 
+Ensure your dependencies are installed as described [here](https://github.com/neondatabase/neon#dependency-installation-notes).
+
 ```sh
-git clone --recursive https://github.com/zenithdb/zenith.git
-make # builds also postgres and installs it to ./tmp_install
-cd test_runner
-pipenv run pytest
+git clone --recursive https://github.com/neondatabase/neon.git

 ### Postgres-specific terms
 
-Due to Zenith's very close relation with PostgreSQL internals, there are numerous specific terms used.
-Same applies to certain spelling: i.e. we use MB to denote 1024 * 1024 bytes, while MiB would be technically more correct, it's inconsistent with what PostgreSQL code and its documentation use.

+# Compute node tools
+
+Postgres wrapper (`compute_ctl`) is intended to be run as a Docker entrypoint or as a `systemd`
+`ExecStart` option. It will handle all the `Neon` specifics during compute node
+initialization:
+- `compute_ctl` accepts cluster (compute node) specification as a JSON file.
+- Every start is a fresh start, so the data directory is removed and
+  initialized again on each run.
+- Next it will put configuration files into the `PGDATA` directory.
+- Sync safekeepers and get commit LSN.
+- Get `basebackup` from pageserver using the returned on the previous step LSN.
+- Try to start `postgres` and wait until it is ready to accept connections.
+- Check and alter/drop/create roles and databases.
+- Hang waiting on the `postmaster` process to exit.
+
+Also `compute_ctl` spawns two separate service threads:
+- `compute-monitor` checks the last Postgres activity timestamp and saves it
+  into the shared `ComputeNode`;
+- `http-endpoint` runs a Hyper HTTP API server, which serves readiness and the
+  last activity requests.
+
+Usage example:
+```sh
+compute_ctl -D /var/db/postgres/compute \
+            -C 'postgresql://cloud_admin@localhost/postgres' \
+            -S /var/db/postgres/specs/current.json \
+            -b /usr/local/bin/postgres
+```
+
+## Tests
+
+Cargo formatter:
+```sh
+cargo fmt
+```
+
+Run tests:
+```sh
+cargo test
+```
+
+Clippy linter:
+```sh
+cargo clippy --all --all-targets -- -Dwarnings -Drust-2018-idioms
+```
+
+## Cross-platform compilation
+
+Imaging that you are on macOS (x86) and you want a Linux GNU (`x86_64-unknown-linux-gnu` platform in `rust` terminology) executable.
+
+### Using docker
+
+You can use a throw-away Docker container ([rustlang/rust](https://hub.docker.com/r/rustlang/rust/) image) for doing that:
+```sh
+docker run --rm \
+    -v $(pwd):/compute_tools \
+    -w /compute_tools \
+    -t rustlang/rust:nightly cargo build --release --target=x86_64-unknown-linux-gnu
+```
+or one-line:
+```sh
+docker run --rm -v $(pwd):/compute_tools -w /compute_tools -t rust:latest cargo build --release --target=x86_64-unknown-linux-gnu
+```
+
+### Using rust native cross-compilation
+
+Another way is to add `x86_64-unknown-linux-gnu` target on your host system:
+```sh
+rustup target add x86_64-unknown-linux-gnu
+```
+
+Install macOS cross-compiler toolchain:
+```sh
+brew tap SergioBenitez/osxct
+brew install x86_64-unknown-linux-gnu
+```
+
+And finally run `cargo build`:
+```sh
+CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_LINKER=x86_64-unknown-linux-gnu-gcc cargo build --target=x86_64-unknown-linux-gnu --release
+```

+//! - Sync safekeepers and get commit LSN.
+//! - Get `basebackup` from pageserver using the returned on the previous step LSN.
+//! - Try to start `postgres` and wait until it is ready to accept connections.
+//! - Check and alter/drop/create roles and databases.
+//! - Hang waiting on the `postmaster` process to exit.
+//!
+//! Also `compute_ctl` spawns two separate service threads:
+//! - `compute-monitor` checks the last Postgres activity timestamp and saves it
+//!   into the shared `ComputeNode`;
+//! - `http-endpoint` runs a Hyper HTTP API server, which serves readiness and the
+//!   last activity requests.
+//!
+//! Usage example:
+//! ```sh
+//! compute_ctl -D /var/db/postgres/compute \
+//!             -C 'postgresql://cloud_admin@localhost/postgres' \
+//!             -S /var/db/postgres/specs/current.json \
+//!             -b /usr/local/bin/postgres
+//! ```
