+This is very simple way of compiling JerryScript. (Please add more so to guide how to build.)
+
+## Get the source
+
+You may know this.
+```
+git clone https://github.com/Samsung/jerryscript.git
+cd jerryscript
+```
+
+## Building
+
+It's based on Ubuntu Linux 14.04 LTS. You may need to read https://github.com/Samsung/jerryscript/wiki/Prerequisites before starting.
+
+```
+make
+```
+For the first time of the make, it'll prepare prerequisites with next message. It may take some time so go grab some coffee.
+```
+Setting up prerequisites... (log file: ./build/prerequisites/prerequisites.log)
+```
+
+After prerequisites are prepared, make will build all supporting platforms and mods. It may also take a while.
+
+If only debug version for linux for development, just do as;
+```
+make debug.linux
+```
+
+without LTO(Link Time Optimization) and debug for linux
+```
+LTO=ff make debug.linux
+```
+
+if something goes wrong, it'll show
+```
+Build failed. See ./build/bin/unittests/make.log for details.
+```
+
+## Testing
+```
+make unittests
+```
+It should have no errors if it is ok.
+
+## Check before committing
+```
+make precommit -j
+```
+This will check any problems in your modifications. may take some time depending on your machine. This is necessary before pull requests but can omit for local commits.
