 <h3>Batch processing</h3>
 <p>This module allow to write scripts in JavaScript that process image files. Batch Processing window consist from three main parts. On top is list of input files and directories.
 You can add directories or individual files to this list. Directories are scanned recursively to find all files even non image files. This list of files is then passed to script in array named <b>files</b>.

+You can leave one or both unchecked then it will attempt to do blind solving. If the position or scale is wrong it can actually
+fail to solve.
+<b>Solution</b> this section contain resulting solution like RA,DEC coordinates center of image, image field of view, orientation as degrees E of N,
+image scale in arcseconds per pixel, number of stars extracted and HFR fitting and eccentricity. Then there is log window for debug information from
+solver.
+</p>
+<p>Then finally there are various action button. Settings button show dialog where you can set path to existing index files or auto download some.
+Extract button will just extract stars from image and it will show their count, HFR and eccentricity. This action doesn't need index files.
+Solve button will try to find coordinates of images. Abort button will stop extraction or solving. Update FITS header will update FITS fits keywords
+with found solution.</p>
+
+<p>In settings dialog you can set path to index files which is by default custom internal one. It also try to locate commonly used path from other
+programs like KStars for astrometry.net index files.

+
+<h3>File Manager</h3>

+This is simple double panel file manager. It can show columns with selected FITS keywords. Each panel have tabs where it easily switch between
+multiple directories. You can copy or move files and directories either inside one panel or between two panels by selecting and then dragging.
+By default files are copies. To move then press Shift key before start dragging. Double click on file will open it in main window if it is image
+or other file it will open default program that is associated with it this file type. You can also drag file to other programs like from default
+file explorer programs that are in system or from file explorer to this program.
