+## About
+
+Tanabata (_jp._ 七夕) is Japanese festival. People generally celebrate this day by writing wishes, sometimes in the form of poetry, on _tanzaku_ (_jp._ 短冊), small pieces of paper, and hanging them on _sasa_ (_jp._ 笹), bamboo. See [this Wikipedia page](https://en.wikipedia.org/wiki/Tanabata) for more information.
+
+Tanabata Project is a software project that will let you enjoy the Tanabata festival. It allows you to store and organize your data as _sasa_ bamboos, on which you can hang almost any number of _tanzaku_, just like adding tags on it.
+
+## Glossary
+
+**Tanabata (_jp._ 七夕)** is a software package project for storing information and organizing it with tags.
+
+**Sasa (_jp._ 笹)** is a file record. It contains 64-bit ID number, the creation timestamp, and the path to the file.
+
+**Tanzaku (_jp._ 短冊)** is a tag record. It contains 64-bit ID number, creation and last modification timestamps, name and description.
+
+**Kazari (_jp._ 飾り)** is a sasa-tanzaku association record. It contains the creation timestamp and associated sasa and tanzaku IDs.
+
+**Hyou (_jp._ 表)** is a table.
+
+**Sasahyou (_jp._ 笹表)** is a table of sasa.
+
+**Sappyou (_jp._ 冊表)** is a table of tanzaku.
+
+**Shoppyou (_jp._ 飾表)** is a table of kazari.
+
+**TDB (Tanabata DataBase)** is a relational database that consists of three tables: _sasahyou_, _sappyou_ and _shoppyou_.
+
+**TDBMS (Tanabata DataBase Management System)** is a management system for TDBs.
+
+**TFM (Tanabata File Manager)** is a TDBMS-powered file manager.
+
+**Tweb (Tanabata web)** is the web user interface for TDBMS and TFM.
+
+## Tanabata library
+
+Tanabata library is a C library for TDB operations. Documentation coming soon...
+
+## Tanabata DBMS
+
+Tanabata Database Management System is the management system for Tanabata databases. Documentation coming soon...
+
+## Tanabata FM
+
+Tanabata File Manager is the TDBMS-powered file manager. Full documentation is [here](docs/fm.md).

+# Tanabata File Manager
+
+## Usage
+
+### Command Line Interface
+
+Build the CLI app using `./build.sh -t tfm [-b <build_dir>]`. For better experience, you can move the executable to the `/usr/bin/` directory (totally safe unless you have another app named `tfm`) or add the directory with it to `PATH`.
+
+Then just open the terminal and run `tfm -h`. If you are running it for the first time, run it with `sudo` or manually create the `/etc/tanabata/` directory and check its permissions. This is the directory where Tanabata programs store their configuration files. If everything is set up properly, you should get the following help message.
+
+```
+(C) Masahiko AMANO aka H1K0, 2022—present
+(https://github.com/H1K0/tanabata)
+
+Usage:
+tfm <options>
+
+Options:
+-h                         Print this help and exit
+-I <dir>                   Initialize new Tanabata database in directory <dir>
+-O <dir>                   Open existing Tanabata database from directory <dir>
+-i                         View database info
+-s                         Set or add
+-u                         Unset or remove
+-e                         Edit or update
+-f <sasa_id or path>       File-sasa menu
+-t <tanzaku_id or name>    Tanzaku menu
+-c <sasa_id>-<tanzaku_id>  Kazari menu (can only be used with the '-s' or '-u' option)
+-w                         Weed (defragment) database
+
+No database connected
+```
+
+So, let's take a look at each option.
+
+Using the `-I <dir>` option, you can initialize an empty TFM database in the specified directory. The app creates empty sasahyou, sappyou and shoppyou files and saves the directory path to the configuration file. The new database will be used the next time you run the app until you change it.
+
+Using the `-O <dir>` option, you can open an existing TFM database in the specified directory. The app checks if the directory contains sasahyou, sappyou and shoppyou files, and if they exist and are valid, saves the directory path to the configuration file. The new database will be used the next time you run the app until you change it.
+
+Using the `-i` option, you can get info about your database. When your hyous were created and last modified, how many records and holes they have, and so on.
+
+Using the `-s` option, you can add new sasa, tanzaku, or kazari.
+
+Using the `-u` option, you can remove sasa, tanzaku, or kazari.
+
+Using the `-e` option, you can update sasa file path or tanzaku name or description. If you want to keep the current value of a field (for example, if you want to change the description of tanzaku while keeping its name), just leave its line blank.
+
+Using the `-f` option, you can manage your sasa. It takes sasa ID when used alone or with the `-u` or `-e` option or target file path when used with the `-s` option. If you want to view the list of all sasa, pass `.` as an argument. For example, `tfm -f 2d` prints the info about sasa with ID `2d` and `tfm -sf path/to/file` adds a new file to the database.
+
+Using the `-t` option, you can manage your tanzaku. It takes tanzaku ID when used alone or with the `-u` or `-e` option or the name of new tanzaku when used with the `-s` option. If you want to view the list of all tanzaku, pass `.` as an argument. For example, `tfm -t c4` prints the info about sasa with ID `c4` and `tfm -st "New tag name"` adds a new tanzaku to the database.
+
+The `-c` option can be used only with the `-s` or `-u` option. It takes the IDs of sasa and tanzaku to link/unlink separated with a hyphen. For example, `tfm -sc 10-4d` links sasa with ID `10` and tanzaku with ID `4d`.
+
+Using the `-w` option, you can _weed_ the database. It's like defragmentation. For example, if you had 4 files with sasa IDs 0, 1, 2, 3 in your database and removed the 1st one, then your database would only have sasa IDs 0, 2, 3 and ID 1 would be a _hole_. Weeding fixes this hole by changing sasa ID 2 to 1, 3 to 2, and updating all related kazari, so for large databases this can take a while.
+
+Using the `-V` option, you just get the current version of TFM.
