-## Writing a basic 9P server
-
-On plan 9 the entire system is build around the idea of namespaces
-and that _"everything is a file"_. For this reason it is very easy to write
-a new 9P fileserver in C since all the boring tasks are implemented in
-libraries. This note describes a minimal program which serves a folder to
-`/mnt/hello9p` containing a single synthetic file with the contents "Hello from 9P!".
-
-## The code
-
-	#include <u.h>
-	#include <libc.h>
-	#include <fcall.h>
-	#include <thread.h>
-	#include <9p.h>
-	
-	void
-	fsread(Req *r)
-	{
-		readstr(r, "Hello from 9P!\n");
-		respond(r, nil);
-	}
-	
-	Srv fs = {
-		.read = fsread,
-	};
-	
-	void
-	main(void)
-	{
-		Tree *tree;
-	
-		tree = alloctree(nil, nil, DMDIR|0555, nil);
-		fs.tree = tree;
-		createfile(tree->root, "hello", nil, 0555, nil);
-	
-		postmountsrv(&fs, nil, "/mnt/hello9p", MREPL | MCREATE);
-	}
-
-## Explanation
-
-The global variable `fs` is a structure which contains function pointers
-to all the 9P handlers, but since I only plan on reading from the file,
-only the `read` field is set. The fsread function calls two helper functions
-from the 9p(2) library which will create a response with the given string as
-the file contents.
-
-In `main` I start by allocating a new file tree, since this 9P server deals with
-a fileserver that has a tree structure, and therefore I don't have to worry
-about how directories are handled for example. A file is added with `createfile`
-to the root of the tree.
-
-The call to `postmountsrv` will mount the 9P server under `/mnt/hello9p`.
-
-## Thats it
-
-This is not very complicated, but see the manpages at 9p(2) and 9pfile(2)
-and intro(5) for more information about the libraries and 9P itself.
