+Release Processes
+=================
+
+Project Release Cadence
+-----------------------
+
+The project currently aims to do a release once every 6 months which will be
+tagged on the master branch. There will be a code freeze (stop merging
+non-essential changes) up to 4 weeks prior to the target release date. The release
+candidates will start appearing after this and only bug fixes or updates
+required for the release will be merged. The maintainers are free to use their
+judgement on what changes are essential for the release. A release branch may be
+created after code freeze if there are significant changes that need merging onto
+the integration branch during the merge window.
+
+The release testing will be performed on release candidates and depending on
+issues found, additional release candidates may be created to fix the issues.

+Version numbering
+~~~~~~~~~~~~~~~~~
+TF-A version is given in Makefile, through several macros:
+
+- VERSION_MAJOR
+- VERSION_MINOR
+- VERSION_PATCH
+
+For example, TF-A v2.10 has VERSION_MAJOR=2, VERSION_MINOR=10 and VERSION_PATCH=0.
+
+This VERSION_PATCH macro is only increased for LTS releases.
+
+Upcoming Releases
+~~~~~~~~~~~~~~~~~
+
+These are the estimated dates for the upcoming release. These may change
+depending on project requirement and partner feedback.
