+containing that image. If directory is specified then it is same as selecting that directory in "Open directory recusivelly". If multiple files are

+<h3>Database tree</h3>
+<p>This is another view that show indexed database as tree. You can add or remove tree filter that construct a tree structure from FITS keywords. Each level of tree
+will be based on this filter. You can specify one keywords multiple times.</p>
+
+<h3>Plate Solving</h3>
+<p>This module can plate solve images and update FITS header with solution for FITS and XISF images.
+<b>Profile</b> this set various parameters that affect star extraction and solving.
+<b>Starting point</b> program will try to automatically determine optimal starting point which helps to speed up solving.
+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.
+</p>
+
+<h3>File Manager</h3>
+<p>
+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.
+</p>
+<p>
+In menu you can select which FITS keywords will be showed. Temporarilly disable loading FITS header or copy file paths of selected files as text.

+
+<h3>Command line options</h3>
+<p>
+Tenmon can be executed from command line. It support these command line options.
+<ul>
+<li><i>--thumb, --thumbnail &lt;path&gt;</i> Generate thumbnail and save it to path. It generate it from first file provided as argument.</li>

+<li><i>--script &lt;script&gt;</i> execute a script from file path same manner as executed from GUI.</li>
+<li><i>--scriptarg &lt;arg&gt>;</i> pass this string as variable scriptarg to a running script.</li>
+<li><i>--outdir &lt;dir&gt;</i> output dir for script execution. By default current working directory is used.</li>
+<li><i>--noexit</i> by default application exit when execution of script specified with --script ends. This prefent that.</li>
+<li><i>-h, --help</i> show help end exit.</li>
+Any other arguments are taken as input paths. If only one file path is specified then that image is open and image list is populated by directory
+containing that image. If directory is specified then it is same as selecting that directory in "Open directory recusivelly". If multiple files are
+specified then image list will contain just these speicified images.

+When exuecting script with --script then these paths are used as input files and directories as in "Batch processing"
