+Coding style used for my bash projects (v2 Sep 2015)
+
+1. Indentation
+
+Using tabs
+Transform old shell scripts using unexpand command
+
+2. Comments
+
+# Some comment
+## Some important comment for the next function
+################################################# Some separation
+
+3. Functions
+
+Every word in a function begins with an uppercase (ex: SomeFunctionDoesThings)
+
+Define functions this way. Use sed ':a;N;$!ba;s/\n{\n/ {\n/g' to adapt when opening bracket is on a new line.
+
+function something {
+	
+}
+
+If function has some arguments, use local variable names that are more readable than $1...$n. Explain via comments what those variables contain if needed.
+
+function anotherthing {
+	local var_name="${1}"
+	local other_var_name="${2}" # This variable contains stuff
+}
+
+Functions should always have return status
+function thirdthing {
+	some_command
+	return $?
+}
+
+3.1 Sub functions
+
+When a function is a subroutine of another function, it is called _SomethingAsSubFunction
+
+4. If statements
+
+If statements will be fully written (word "if" must be used). then is written on the same line.
+(Use sed ':a;N;$!ba;s/]\n\t*then/]; then/g' to convert files to this format... Replace "],new line, zero or more tabs, then" by "; then")
+if [ something ]; then
+	stuff
+else
+	other stuff
+fi
+
+5. Logging
+
+A logging function is available with the following levels of logging:
+
+- DEBUG: Only log this when DEBUG flas is set in program. Any command forged for eval should be logged by this.
+- NOTICE: Standard messages
+- WARN: Requires attention
+- ERROR: Program produced an error but continues execution
+- CRITICAL: Program execution is halted
+
+6. Eval
+
+The eval command should always contain 2>1&.
+There's a special case where this is needed:
+eval "some;commands" 2>> "$LOG_FILE" in order to get error messages into the log.

 ## Installation
 
+Please note that development of version 1.1 has begun. Stable release is v1.01.
+
 Osync has been designed to not delete any data, but rather make backups of conflictual files or soft deletes.
 Nevertheless, you should always have a neat backup of your data before trying a new sync tool.
 
 You can download the latest stable release of Osync at www.netpower.fr/osync
 You may also get the last development version at https://github.com/deajan/osync with the following command
 
-	$ git clone https://github.com/deajan/osync
+	$ git clone -b "v1.01" https://github.com/deajan/osync
 	$ sh install.sh
 
 Osync will install itself to /usr/local/bin and an example configuration file will be installed to /etc/osync
