+# WordClock Buildroot
+
+## Requirements
+* Check out buildroot requirements: https://buildroot.org/downloads/manual/manual.html#requirement
+* About __15GB__ of free disk space
+
+## Compilation
+
+1. Clone repository:
+  
+  SSH: `git clone [email protected]:OpenLarry/WordClock-Buildroot.git`
+  
+  HTTP: `git clone https://github.com/OpenLarry/WordClock-Buildroot.git`
+2. Change directory:
+  
+  `cd WordClock-Buildroot`
+3. Download submodules:
+  
+  `git submodule init`
+  
+  `git submodule update`
+4. Set buildroot configuration:
+  
+  `make olimex_imx233_olinuxino_wordclock_defconfig`
+5. Run build process:
+  
+  `make`
+6. Wait. Build time depends on hardware configuration and internet speed.
+7. Change into generated output directory:
+  
+  `cd output/images`
+8. Here you can find the SD card image (`sd-card.img`) and all parts of it:
+  
+  * `u-boot.sd` boot loader
+  * `uboot-env.bin` boot loader configuration
+  * `uImage.imx233-olinuxino` linux kernel
+  * `rootfs.squashfs` root filesystem
+  
+9. Copy to SD card:
+  
+  `dd if=sd-card.img of=/dev/mmcblk0 bs=4096` (replace mmcblk0 with your card reader device)
+
+## About buildroot
+
+Buildroot is a simple, efficient and easy-to-use tool to generate embedded
+Linux systems through cross-compilation.
+
+The documentation can be found in docs/manual. You can generate a text
+document with 'make manual-text' and read output/docs/manual/manual.text.
+Online documentation can be found at http://buildroot.org/docs.html
+
+To build and use the buildroot stuff, do the following:
+
+1. run 'make menuconfig'
+2. select the target architecture and the packages you wish to compile
+3. run 'make'
+4. wait while it compiles
+5. find the kernel, bootloader, root filesystem, etc. in output/images
+
+You do not need to be root to build or run buildroot.  Have fun!
+
+Buildroot comes with a basic configuration for a number of boards. Run
+'make list-defconfigs' to view the list of provided configurations.
+
+Please feed suggestions, bug reports, insults, and bribes back to the
+buildroot mailing list: [email protected]
+You can also find us on #buildroot on Freenode IRC.
