 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.
+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 Neon installation consists of compute nodes and a Neon storage engine.
-
-Compute nodes are stateless PostgreSQL nodes backed by the Neon 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.
 
 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.
+- 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.
 
-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
+See developer documentation in [/docs/SUMMARY.md](/docs/SUMMARY.md) for more information.

+    //   2. In an exact copy of the address space at the time of fork.
+    // A variety of problems scan occur now:
+    //   1. T tries to grab a lock that was locked at the time of fork.
+    //      It will wait forever since in its address space, the lock
+    //      is in state 'taken' but the thread that would unlock it is
+    //      not there.
+    //   2. A rust object that represented some external resource in the
+    //      parent now got implicitly copied by the the fork, even though
+    //      the object's type is not `Copy`. The parent program may use
+    //      non-copyability as way to enforce unique ownership of an
+    //      external resource in the typesystem. The fork breaks that
+    //      assumption, as now both parent and child process have an
+    //      owned instance of the object that represents the same
+    //      underlying resource.
+    // While these seem like niche problems, (1) in particular is
+    // highly relevant. For example, `malloc()` may grab a mutex internally,
+    // and so, if we forked while another thread was mallocing' and our
+    // pre_exec closure allocates as well, it will block on the malloc
+    // mutex forever

+    // With this specific pre_exec() closure, the non-error path doesn't allocate.
+    // The error path uses `anyhow`, and hence does allocate.

+//! Abstraction to create & read pidfiles.
+//!
+//! A pidfile is a file in the filesystem that stores a process's PID.
+//! Its purpose is to implement a singleton behavior where only
+//! one process of some "kind" is supposed to be running at a given time.
+//! The "kind" is identified by the pidfile.
+//!
+//! During process startup, the process that is supposed to be a singleton
+//! must [claim][`claim_for_current_process`] the pidfile first.
+//! If that is unsuccessful, the process must not act as the singleton, i.e.,
+//! it must not access any of the resources that only the singleton may access.
+//!
+//! A common need is to signal a running singleton process, e.g., to make
+//! it shut down and exit.
+//! For that, we have to [`read`] the pidfile. The result of the `read` operation
+//! tells us if there is any singleton process, and if so, what PID it has.
+//! We can then proceed to signal it, although some caveats still apply.
+//! Read the function-level documentation of [`read`] for that.
+//!
+//! ## Never Remove Pidfiles
+//!
+//! It would be natural to assume that the process who claimed the pidfile
+//! should remove it upon exit to avoid leaving a stale pidfile in place.
+//! However, we already have a reliable way to detect staleness of the pidfile,
+//! i.e., the `flock` that [claiming][`claim_for_current_process`] puts on it.
+//!
+//! And further, removing pidfiles would introduce a **catastrophic race condition**
+//! where two processes are running that are supposed to be singletons.
+//! Suppose we were to remove our pidfile during process shutdown.
+//! Here is how the race plays out:
+//! - Suppose we have a service called `myservice` with pidfile `myservice.pidfile`.
+//! - Process `A` starts to shut down.
+//! - Process `B` is just starting up
+//!     - It `open("myservice.pid", O_WRONLY|O_CREAT)` the file
+//!     - It blocks on `flock`
+//! - Process `A` removes the pidfile as the last step of its shutdown procedure
+//!     - `unlink("myservice.pid")
+//! - Process `A` exits
+//!     - This releases its `flock` and unblocks `B`
+//! - Process `B` still has the file descriptor for `myservice.pid` open
+//! - Process `B` writes its PID into `myservice.pid`.
+//! - But the `myservice.pid` file has been unlinked, so, there is `myservice.pid`
+//!   in the directory.
+//! - Process `C` starts
+//!     - It `open("myservice.pid", O_WRONLY|O_CREAT)` which creates a new file (new inode)
+//!     - It `flock`s the file, which, since it's a different file, does not block
+//!     - It writes its PID into the file
+//!
+//! At this point, `B` and `C` are running, which is hazardous.
+//! Morale of the story: don't unlink pidfiles, ever.
