ReadCIS installation requires 165kb disk space, of which 70kb is the documentation. 

 1) Copy all files into the \APP\READCIS\ directory on any disk, preferably a flash SSD. Press <Psion-+> to create this directory, be sure to type the name as \APP\READCIS , the backslash at the beginning in critical.
 2) Press <Psion-I> to install the ReadCIS icon.
 3) Set the disk to A, B or Internal to match the disk that contains \APP\READCIS\.
 4) Press <Tab>.
 5) Cursor to \APP\READCIS\.
 6) Press <Enter>.
 7) Cursor to "Readcis.opa". Choose carefully, there are many files with similar names.
 8) Press <Enter>. The ReadCIS icon will appear.
 9) Press <Enter> to start ReadCIS.
10) Press <Psion-+> to Configure Names.
11) Press <Psion-H> to Read Documentation.
12) Accept the default file _Readcis_ , press <Enter>.
13) The documentation is stored in Psion Data format. The first screen explains how to navigate, or convert it to a text file for reading with your PC word processor or a Psion text viewer, it is too large to open with Psion Word. Please read topics 2.0 through 2.8.1 for instructions on completing the new Names dialogs. After you are familiar with the program you may wish to delete some records and compress the file, or remove it altogether and rely on the <Help> facility.  However, please retain a copy of the complete data file for reference. (I know the <Help> file says it is for version 1.4, it'll be revised soon.)
