+Library for a SPI wrapper 
+created by IGB
+================================================
 
-Created by IGB.
+This library allows the user to:
 
-Arduino Library for wrapping the SPI class in a simpler way.
-Create an object to open a communication channel.
-Use the object and its methods to transfer data.
-All underlying activities are encapsulated.
+* Create an object to open a spi communication channel with underlying complexity encapsulated
+* Use the object and its methods to transfer data with automatically setting slave select pins
+* Configure for different data sizes arrays, 8bit, 16bit, 32bit
+* Configure the other SPI options like frequency
+
+An example is included to get you started.
+
+* **/examples** - Example sketches for the library (.ino). Run these from the Arduino IDE
+* **/src** - Source files for the library (.cpp, .h)
+* **keywords.txt** - Keywords from this library that will be highlighted in the Arduino IDE
+* **library.properties** - General library properties for the Arduino package manager

+Documentation
+--------------
+The library enables the following functions:
+
+#### General methods for class
+	ComDriverSpi();
+    ComDriverSpi(uint8_t slaveSelectPin);
+    ComDriverSpi(uint8_t slaveSelectPin, uint32_t frequency);
+
+#### Write and read to SPI bus
+    bool writeSpi(uint8_t data[], uint32_t sizeToWrite, transferOption_t transferOption = transferStartEnd);
+    bool readSpi(uint8_t data[], uint32_t sizeToRead, transferOption_t transferOption = transferStartEnd);
+    bool writeReadSpi(uint8_t dataWrite[], uint32_t sizeToWrite, uint8_t dataRead[], uint32_t sizeToRead, transferOption_t transferOption = transferStartEnd);
+
+    void writeSpiManual(uint8_t dataWrite[], uint32_t sizeToWrite);
+    void readSpiManual(uint8_t dataRead[], uint32_t sizeToRead);
+    
+    void writeSpiManual8(uint8_t data);
+    uint8_t readSpiManual8(void);
+    void writeSpiManual16(uint16_t data);
+    uint16_t readSpiManual16(void);
+    void writeSpiManual32(uint32_t data);
+    uint32_t readSpiManual32(void);
+
+#### Configuration
+    void startWriteSpiManual(void);
+    void endWriteSpiManual(void);
+    void setSlaveSelectPin(uint8_t slaveSelectPin);
+    uint8_t getSlaveSelectPin();
+    void setFrequency(uint32_t frequency);
+    uint32_t getFrequency();
+    void setDataMode(uint8_t dataMode);
+    uint8_t getDataMode();
+    void setDataOrder(uint8_t dataOrder);
+    uint8_t getDataOrder();
+    void setTransferOption(transferOption_t transferOption);
+    transferOption_t getTransferOption();
