.SH DESCRIPTION
.PP
/etc/apk/repositories is the list of package repositories \fBapk\fR(8) uses to
retrieve package files for installation.\& Each line of this file specifies the
location of a package repository, and optionally a tag.\&
.PP
The location may be an \fIhttp://\fR, \fIhttps://\fR, or \fIftp://\fR URL, or the path to a
directory on the local filesystem.\& A tagged repository is prefixed with the
\fB@tag\fR specifier, followed by a space and the repository location.\& For more
information about repository tags, see \fBapk\-world\fR(5).\&
.PP
.SH REPOSITORY LAYOUT
.PP
Each repository must store an index at \fB$repository/$arch/APKINDEX.\&tar.\&gz\fR.\& See
\fBapk\-index\fR(8) for information about generating this file.\& The packages
themselves are stored at \fB$repository/$arch/$pkgname\-$pkgver\-r$pkgrel.\&apk\fR.\&
.PP
\fBapk\fR(8) verifies that each of these files has a valid cryptographic signature
unless explicitly told not to via the \fB\-\-allow\-untrusted\fR flag.\& See
\fBabuild\-keygen\fR(1) for information about generating keys, \fBapk\-keys\fR(5) to add
keys to the list of trusted keys, \fBabuild\-sign\fR(1) for information about using
these keys to sign files, and \fBapk\-verify\fR(8) for information about verifying
those signatures.\&
.PP
.SH UPDATING INDICIES
.PP
\fBapk\fR(8) fetches and stores the index for each package repository at
\fB/var/cache/apk\fR.\& To fetch fresh indicies for all configured repositories, use
\fBapk\-update\fR(8).\&
