+# What is IFOS3D?
+
+**IFOS2D** (**I**nversion of **F**ull **O**bserved **S**eismograms) is a 3D elastic full waveform inversion code.  
+The inversion problem is solved by a conjugate gradient method and the gradients are computed in the frequency domain with the adjoint method.  
+The forward modeling is done by a time domain finite difference scheme. 
+
+IFOS2D is the reverse (inverse) of our 3D finite difference forward solver [**SOFI3D**](https://git.scc.kit.edu/GPIAG-Software/SOFI3D).
+
+The [**manual**](https://git.scc.kit.edu/GPIAG-Software/IFOS3D/wikis/home) can be downloaded [here](https://git.scc.kit.edu/GPIAG-Software/IFOS3D/wikis/home).
