+## Module Layout
+
+- `table.rs`: adjacency table
+  - Tree data structure on vector
+  - Inode allocation by `MIN_ID + index`
+  - Should be use behind lock
+- `handle.rs`: Mount Handle
+  - NewType wrapper for dropping
+- `adapter` module: adapter between internal data structure(tree-like) and `libfuse`
+  - `error.rs`: a centralized way to handle error
+  - `fuse.rs`: adaptor between internal data structure and `libfuse`
+  - `reply.rs`: collection of constructor for replay from `libfuse`
+  - `handle.rs`: file handle table
+  - `template.rs`: A NewType wrapper to force user explicitly clone(`as_filesystem`) filesystem
+- `entry` module: collection of single file
+  - `tar.rs`: a NewType wrapper for `Tree<Entry>`
+  - `ro.rs`: read only normal file(mapped from tar ball)
+  - `rw.rs`: read/write normal file(in memory)
+- `resource.rs`: Resource counter, much like `semaphore`
+- `mkdtemp.rs`: a safe wrapper around `libc::mkdtemp`
+
+## Prerequisite knowledge
+
+### Filesystem in Userspace
+
+> FUSE, or Filesystem in Userspace, is a software interface that allows non-privileged users to create their own file systems in Linux without modifying the kernel.  It acts as a bridge between the kernel's virtual filesystem layer and user-space programs.
+
+Traditionally, we have to develop a dedicated kernel module for a filesystem.
+
+FUSE workaround this problem by providing connection, to set up a FUSE, program need to...
+
+1. acquire a FUSE connection(similar to unix socket).
+2. poll the socket until a connection(similar to a new connection on tcp socket)
+3. read that connection to acquire an OPCODE
+4. follow OPCODE to parse the request
+
+example of OPCODE: `READ`, `LOOKUP`, `OPEN`, `RMDIR`...
+
+[list](https://github.com/libfuse/libfuse/blob/6476b1c3ccde2fc4e8755858c96debf55aa0574b/lib/fuse_lowlevel.c#L2619) of OPCODE
+
+In this project, we use `fuse3`, which is a wrapper over `libfuse-sys`.
+
+To get started, you can follow [main.rs](https://github.com/Sherlock-Holo/fuse3/blob/master/examples/src/memfs/main.rs) from `fuse3`'s example.
+
+#### `INODE`
+
+`INODE` is an id generate by filesystem, program providing that can set `INODE` to whatever you want, but make sure it's unique for same file(dictionary).
+
+You can get inode with `stat`
+```
+❯ stat .
+  File: .
+  Size: 128             Blocks: 0          IO Block: 4096   directory
+Device: 2ah/42d Inode: 13553287    Links: 1
+Access: (0775/drwxrwxr-x)  Uid: ( 1000/   eason)   Gid: ( 1000/   eason)
+Access: 2024-04-28 19:44:43.208376257 +0800
+Modify: 2024-05-20 21:39:42.300855512 +0800
+Change: 2024-05-20 21:39:42.300855512 +0800
+ Birth: 2024-04-28 19:44:43.208376257 +0800
+```
+
+Note that zero `INODE` means unspecified(null in C's language). 
+
+#### `File Handle`
+
+In the context of filesystem of libc, you might be familiar with `file descriptor`, `file descriptor` is a `uint64` generate secquetially by kernel(unique for each process).
+
+`File handle` is similar to `file descriptor`, but it sit between kernel and FUSE provider, generated by FUSE provider and unique for each FUSE connection.
+
+When a file open, FUSE provider generate a `uint64`, and file handle is pass as parameter for later operations.
+
+FUSE provider should implement a way to retrieve file's session by `file handle`.
+
+> file's session includes `bytes readed`, `open flag`...
+
+Note that zero `File Handle` means unspecified(null in C's language), generating a 0 `File Handle` is not allowed. 
+
+#### OPCODE `READDIR`
+
+> Read directory.
+
+similar to what `ls -a` provide, list dictionary including `.` and `..`
+
+parameters:
+1. parent `INODE`(could be unspecified, unspecified is root)
+2. offset 
+3. size
+
+return: list of file(dictionary)
+
+example(ignore the fact that many file is missing):
+
+```
+❯ ls -a /
+.   ..   boot   etc   lib    lib64   media
+```
+
+| offset  | size  | output |
+|  ----  | ----  | --- |
+| 0  | 1 | `.` |
+| 2 | 3 | `etc`, `lib`, `lib64` |
+
+#### OPCODE `OPEN`
+
+> Open a file. Open flags (with the exception of O_CREAT, O_EXCL, O_NOCTTY and O_TRUNC) are available in flags
+
+parameters:
+1. file `INODE`(could be unspecified, unspecified is root)
+2. flag
+
+return: File Handle
+
+`O_CREAT` should be handle by kernel instead.
+

+### Control Group(linux)
+
+> In Linux, control groups (cgroups for short) act like a resource manager for your system. It lets you organize processes into groups and set limits on how much CPU, memory, network bandwidth, or other resources they can use.
+
+> cgroup is abbr for control group
+
+In practice, linux kernel expose cgroup's interface by vfs.
+
+To get started, you can follow [it article](https://access.redhat.com/documentation/zh-tw/red_hat_enterprise_linux/6/html/resource_management_guide/sec-creating_cgroups) from red hat to create one.
+
+In this project, we use `cgroups_rs`, which is an abstraction over underlying vfs.
