 Welcome to Xmipp documentation!
-========================================
+========================================
+drawing
+
+Xmipp is a suite of image processing programs, primarily aimed at single-particle 3D electron microscopy, 
+designed and managed by the `Biocomputing Unit <http://biocomputingunit.es/>` located in Madrid, Spain.
+
+The Xmipp project is divided into four repositories:`xmipp <https://github.com/I2PC/xmipp>`,
+ `xmippCore <>`, `scipion-em-xmipp <https://github.com/I2PC/scipion-em-xmipp>` and `xmippVix <https://github.com/I2PC/xmippViz>`, 
+ are automatically downloaded during the installation process.
+
+Getting started
+----------------
+The recommended way for users (not developers) to install and use Xmipp is via the Scipion
+ framework, where you can use Xmipp with other Cryo-EM-related software. Xmipp will be installed during Scipion installation 
+ (pay attemption on the -noXmipp flag). The Scipion installer should take care of all dependencies for you, however, you can make 
+ its life easier if you have your compiler, CUDA and HDF5 library ready and available in the standard paths. Read the installation 
+ page for more details about these softwares requirements. Follow the official installation guide of Scipion for more details.
