Introduction ~~~~~~~~~~~~ The Shift Log Tool (SLT) is envisioned as both an “on-line” tool, used in real-time by the operators at the two telescope sites, and as an “off-line” tool, used at any of the three SKA sites. Its intention is to collate and then provide access to a record of the major events occurring during an operator’s shift. For instructions on developing the SLT UI, see the `README `_ It communicates with ska-oso-slt-services via a REST API see the `REST API `_
