+# RawTherapee
+A powerful cross-platform raw photo processing program
+
+RawTherapee is a cross-platform raw photo processing program, released under the GNU General Public License Version 3. It is written in C++ using a GTK+ front-end and a patched version of dcraw for reading raw files. It is notable for the advanced control it gives the user over the demosaicing and developing process.

+
+## Compilation, patching and Git
+Refer to RawPedia for dependency requirements:
+http://rawpedia.rawtherapee.com/Linux
+
+The instructions below will be merged into that article on RawPedia soon.
+
+Clone the source code:
+`git clone https://github.com/Beep6581/RawTherapee ~/repo-rt`
+or update a previously cloned repository:
+`cd ~/repo-rt && git fetch`
+
+Apply a patch:
+If you want to apply a patch, use "git apply" if you just want to apply without committing, or "git am" if you want to automatically apply and commit:
+`git apply /downloads/some.patch`
+or
+`git am /downloads/some.patch`
+
+Compile:
+To find out how many threads your CPU supports, run:
+`grep -c processor /proc/cpuinfo`
+Then replace the number in `-j8` below with this number. This will make compilation faster but it will have no effect on the speed of running RawTherapee.
