 # 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.

 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.

-## 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!

-        // ask.  It turns out that making large allocations with 'posix' doesn't
-        // work very well with autoscaling. The behavior we want is that:
-        //
-        // 1. You can make large DSM allocations, larger than the current RAM
-        //    size of the VM, without errors
-        //
-        // 2. If the allocated memory is really used, the VM is scaled up
-        //    automatically to accommodate that
-        //
-        // We try to make that possible by having swap in the VM. But with the
-        // default 'posix' DSM implementation, we fail step 1, even when there's
-        // plenty of swap available. PostgreSQL uses posix_fallocate() to create
-        // the shmem segment, which is really just a file in /dev/shm in Linux,
-        // but posix_fallocate() on tmpfs returns ENOMEM if the size is larger
-        // than available RAM.
-        //
-        // Using 'dynamic_shared_memory_type = mmap' works around that, because
-        // the Postgres 'mmap' DSM implementation doesn't use
-        // posix_fallocate(). Instead, it uses repeated calls to write(2) to
-        // fill the file with zeros. It's weird that that differs between
-        // 'posix' and 'mmap', but we take advantage of it. When the file is
-        // filled slowly with write(2), the kernel allows it to grow larger, as
-        // long as there's swap available.
-        //
-        // In short, using 'dynamic_shared_memory_type = mmap' allows us one DSM
-        // segment to be larger than currently available RAM. But because we
-        // don't want to store it on a real file, which the kernel would try to
-        // flush to disk, so symlink pg_dynshm to /dev/shm.

-# 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.
