 # bit-inspector
 
-Detects bit rotten files in the given directory to keep your files forever.
+"Bit Inspector" (Bir) is a tool to manage files. It is inspired by Git, but its goals are slightly different.
+ * Hash sum of files is tracked
+ * Detects bit rots to keep your files forever
+ * Files are handled in a "Bir repository"
+ * You can clone a remote repository
+ * You can save your local repository to remote repository.
 
-It is inspired by:
 
- * https://github.com/ambv/bitrot
- * https://github.com/laktak/chkbit-py
+## How to build "Bit Inspector" on your own 
 
-## How it works
-
-You go to a directory.
-You run the command bir:
- * All files in this directory are inspected, new files are added to the database, deleted files are removed from the database.
- * If the file last modification date in database and on the disk is the same, but the content checksum is different, then a bit rot is detected.
-
-This program cannot restore files with bitrot.
- * You have to backup up your files (do snapshots).
+```
+git clone https://code.nanoboot.org/nanoboot/bit-inspector
+cd bit-inspector
+mvn clean install
+```
 
 ## How to setup your environment on Linux
 
+
+Add to your .bashrc:
+
+    alias bir='java -jar {path to bit-inspector jar with dependencies file}/bit-inspector-0.0.0-SNAPSHOT-jar-with-dependencies.jar'
+
+## Syntax
+
+bir {command} [{arg1} {arg2} {argn}]
+
 Example:
+```
+bir clone dir=/home/johndoe/mydir url={local path or s3 bucket or FTP server or website url}
+```
 
-    alias bir='java -jar /rv/data/desktop/code/code.nanoboot.org/nanoboot/bit-inspector/target/bit-inspector-0.0.0-SNAPSHOT-jar-with-dependencies.jar'
+### Arguments
 
-## Usage
+dir={path to directory}
+ * default:. (current working directory)
 
-"Bit Inspector" creates an SQLite database - file ".bir.sqlite3" in the current directory.
+## Bir repository
 
-There is also created the  file ".bir.sqlite3.sha512", which contains the current hash sum of file ".bir.sqlite3".
+To use Bir, a Bir repository is needed.
+
+You can:
+ * clone a remote Bir repository
+ * or use an existing local Bir repository
+ * or create a new empty Bir repository
+ * or create a new Bir repository using an existing directory
+
+### Cloning a remote repo
+
+#### S3
+```
+bir clone {endpoint url}/{bucket name}
+```
+Then you will be asked for access key and secret key.
+
+### Using an existing bir repository
+
+### Creating a new empty Bir repository
+
+Go to wanted directory or use argument dir={path to wanted directory} and run:
+
+```
+bir init [dir to wanted directory]
+```
+
+### Creating a Bir repository using an existing directory
+
+
+Go to wanted directory or use argument dir={path to wanted directory} and run:
+
+```
+bir init [dir to wanted directory]
+```
+
+### Commands
+
+### init
+
+Init commands creates new directory .bir with its structure
+```
+bir init [dir={path to directory}]
+```
+
+
+bir – object storage – local/s3/ftp
+
+ bir remote add {remote name}
+bir clone {remote name}
+bir save
+bir push {remote name}
+bir fetch
+bir pull
+bir status
+
+directories:
+.bir
+.bir objects
+
+
+Table FILE – add new columns – linux_rights, owner, group
+
+
+###
+
+## Structure of .bir directory
+
+.bir
+.bir/objects
+.bir/bir.sqlite3 ... an SQLite database
+.bir/.bir.sqlite3.sha512 ...last calculated hash sum of file ".bir.sqlite3".
+
+## File .birignore
 
 You can create file .birignore containing the names of the files/directories you wish to ignore
 * each line should contain exactly one name
 * lines starting with # are skipped
 * you may use Unix shell-style wildcards
 
+## Detection of bit rots
+
+If the file last modification date in database and on the disk are the same, but the calculated checksum is different, then a bit rot was is probably detected.
+
+
+New files are added to the database, deleted files are removed from the database.
+ 
+
+This program cannot restore files with bitrot.
+ * You have to backup up your files (do snapshots).
