+#' Start date and end date are in "MM/D(D)/YYYY" format. You can extract this
+#' information into multiple columns with a \code{separate} function from the
+#' \pkg{tidyr} package. This is mostly for convenience. Be mindful of two things:
+#' 1) Dates are dates of first and last action, and not necessarily the escalation
+#' to war, per se. 2) dates can be "missing". These are -9s, and are commonplace
+#' when archival research can't pinpoint an exact day something happened.
+#'
+#' Observations select at the *confrontation*-level where maximum fatalities are
+#' greater than 1,000 and at the *participant*-level where 1) the participant
+#' engaged in at least an attack during this confrontation and 2) there are no
+#' instances where a participant dropped in/out on the same side of a
+#' multilateral confrontation or switched sides. For illustration's sake, the
+#' Taiwan Straits Crises saw several appearances by the United States, but only
+#' one instance (for six days in Feb. 1953) where the U.S. engaged in an attack.
+#' World War II is a classic case of participants switching sides (France did
+#' so three times), but it also happened in the War of Latvian Independence as
+#' well (MIC#2604). The War of Attrition also saw the Russians reappear twice.
+#' Cases like these aren't included, mostly for convenience sake. In total, nine
+#' cases with 1,000 maximum fatalities or more at the confrontation-level are
+#' excluded because of this. Of these nine cases, World War II and the Vietnam
+#' War are the most conspicuous by their absence. Data come from version 1.01 of
+#' the Militarized Interstate Confrontation data.
+#'
+#' Opponent fatalities are strictly dyadic and are derived from the Militarized
+#' Interstate Events data.
+#'
+#' Capabilities and democracy data come from \pkg{peacesciencer} for a forthcoming
+#' v. 1.2.0 release. See package for more information, though references are
+#' also included below. Variables are mostly lagged to the year prior to the
+#' participant observation year. However, there are several cases in the data
+#' that are born into war (see: India, Pakistan, North and South Korea, North
+#' and South Vietnam). In cases of missing data, information from the observation
+#' year is used.
