+
+The aptly-named International Gemini Observatory operates twin 8-m optical/near-infrared telescopes from 
+Maunakea on the Big Island of Hawaii and Cerro Pachón in Chile, providing full sky coverage in declination and 
+6 hours of difference in longitude. Gemini North is a neighbor of AEON+ facility CFHT and Gemini South shares 
+Cerro Pachón with SOAR and the Vera C Rubin Observatory. Gemini is a founding member of AEON along with Las 
+Cumbres Observatory and SOAR.
+
+Each telescope is equipped with optical and near-infrared imagers, medium resolution optical and near-infrared 
+spectrographs, and optical high-resolution spectrographs. Gemini North also has the Altair near-infrared 
+adaptive-optics system with laser guide star. Up to three instruments are usable at each telescope on a given 
+night and switching between them takes less than a minute. An eight channel instrument, SCORPIO, is under 
+construction for Gemini South that will provide simultaneous imaging or longslit spectroscopy from 0.4 to 2.4 
+microns. 
+
+Gemini operates in queue mode on the majority of nights. Staff observers match observations to the current 
+conditions. New observations, including Targets of Opportunity, are easily inserted into the observing plans. 
+Gemini works within AEON using an existing [API](https://github.com/bryanmiller/gsselect) and plugins to the 
+[TOM Toolkit](https://tom-toolkit.readthedocs.io/en/stable/). Software improvements that are 
+[under development](https://www.gemini.edu/observing/operations-development) will provide enhanced automation based on 
+25 years of queue operations experience, more capable APIs, and a dynamic scheduler that will create 
+observing plans for both telescopes together. This system, the Gemini Program Platform (GPP), is expected to 
+enter operations in 2026.
+
+The international Gemini Observatory, a program of NSF NOIRLab, is managed by the Association of Universities 
+for Research in Astronomy (AURA) under a cooperative agreement with the U.S. National Science Foundation on 
+behalf of the Gemini partnership: the U.S. National Science Foundation (United States), the National Research 
+Council (Canada), Agencia Nacional de Investigación y Desarrollo (Chile), Ministerio de Ciencia, Tecnología e 
+Innovación (Argentina), Ministério da Ciência, Tecnologia, Inovações e Comunicações (Brazil), and Korea 
+Astronomy and Space Science Institute (Republic of Korea).
