-Zenith is a serverless open source alternative to AWS Aurora Postgres. It separates storage and compute and substitutes PostgreSQL storage layer by redistributing 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.
+
+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
+[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 Zenith installation consists of compute nodes and Zenith storage engine.
+A Neon installation consists of compute nodes and a Neon storage engine.
 
-Compute nodes are stateless PostgreSQL nodes, backed by Zenith storage engine.
+Compute nodes are stateless PostgreSQL nodes backed by the Neon storage engine.
 
-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.
+The Neon storage engine consists of two major components:
+- 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 - Zenith storage implementation.
+- 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.
+- WAL redo - service that builds pages from base images and WAL records on Page service request
 
 ## 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 etcd cmake postgresql-client
+```
+* On Fedora, these packages are needed:
+```bash
+dnf install flex bison readline-devel zlib-devel openssl-devel \
+  libseccomp-devel perl clang cmake etcd postgresql postgresql-contrib
 ```
 
-[Rust] 1.56.1 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 etcd 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 `./scripts/pysync` (requires poetry) in the project directory.

 ### 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.

-//!
-//! Postgres wrapper (`zenith_ctl`) is intended to be run as a Docker entrypoint or as a `systemd`
-//! `ExecStart` option. It will handle all the `zenith` specifics during compute node
-//! initialization:
-//! - `zenith_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 `zenith_ctl` spawns two separate service threads:
-//! - `compute-monitor` checks the last Postgres activity timestamp and saves it
-//!   into the shared `ComputeState`;
-//! - `http-endpoint` runs a Hyper HTTP API server, which serves readiness and the
-//!   last activity requests.
-//!
-//! Usage example:
-//! ```sh
-//! zenith_ctl -D /var/db/postgres/compute \
-//!            -C 'postgresql://zenith_admin@localhost/postgres' \
-//!            -S /var/db/postgres/specs/current.json \
-//!            -b /usr/local/bin/postgres
