+###### Getting started {#getting_started}
+
+On this page you find a link to the source code of the Jülich-München
+program and a guide to help you compiling and running the code. In
+addition the main files as well as special files are listed.
+
+##### Common code version {#common_code_version}
+
+` * `[`Download`` ``recent`` ``JM`` ``code`` ``package`](jmcode_download "wikilink")
+
+##### Compilation
+
+` * For the recent git-versions: follow the instructions on the code's readme page (`[`https://kkr.iffgit.fz-juelich.de/kkrjm/page/index.html`](https://kkr.iffgit.fz-juelich.de/kkrjm/page/index.html "wikilink")`)`
+
+` * Versions older than 3.0: see `[`here`](jmcode_install_old "wikilink")
+
+\<WRAP center round important 80%\> Always try to save the executable
+together with the corresponding inc.p file in a separated folder.
+</WRAP>
+
+##### Executing kkr.x in parallel {#executing_kkr.x_in_parallel}
+
+After compiling the code you can simply execute //kkr.x// which will
+start the calculation in the directory where you currently are.
+[Here](jumu:mpiexecution_kkrjm "wikilink") you find more information
+about how to execute the program on more than one core.
+
+##### Main input files {#main_input_files}
+
+` * `[`inputcard`` ``file`](jumu:input_file "wikilink")\
+` * `[`potential`` ``file`](jumu:potential_file "wikilink")\
+` * `[`shapefun`` ``file`](kkrnano:shapefun "wikilink")
+
+##### Special input files {#special_input_files}
+
+` * `[`scoef`` ``file`](scoef_file "wikilink")` (see KKRimp program for details)`\
+` * `[`nonco_angle.dat`` ``file`](nonco_angle.dat_file "wikilink")` (see `[`SOC`` ``calculations`](jumu:soc "wikilink")` for details)`
+
+##### Some output files {#some_output_files}
+
+` * `[`lmdos.??.?.dat`](jumu:lmdos-files "wikilink")` when RUNOPT ''lmdos   '' is used`\
+` * `[`complex.dos`](jumu:complex_DOS "wikilink")\
+` * `[`output.???.txt`](jumu:output_000 "wikilink")\
+` * `[`out_timing.???.txt`](jumu:out_timing_000 "wikilink")\
