+OP-TEE
+=======
+
+This is the repository of OP-TEE (Open Portable Trusted Execution Environment),
+the open-source TEE maintained by Linaro, with initial contributions from
+STMicroelectronics, Ericsson and Linaro Limited.
+
+What OP-TEE is
+------
+
+OP-TEE is designed primarily to rely on the ARM TrustZone(R) technology as the
+underlying hardware isolation mechanism. However, it has been structured to be
+compatible with any isolation technology suitable for the TEE concept and goals,
+such as running as a virtual machine or on a dedicated CPU.
+
+The main design goals for OP-TEE are:
+-	Isolation - the TEE provides isolation from the Rich OS (typically,
+	Linux/Android) and it protects the Trusted Applications (TAs) it
+	executes from each other, using underlying HW support,
+-	Small footprint - the TEE should remain small enough so that the TEE
+	core, including all the code and data required to provide isolation, can
+	reside in a reasonable amount of on-chip memory,
+-	Portability - the TEE must be easily pluggable to different
+	architectures and available HW, and it has to support various setups
+	such as multiple TEEs or multiple client OSes.
+
+Repository structure
+------
+
+OP-TEE is composed of three gits:
+-	The optee-client git, containing the source code for the TEE client
+	library in Linux. This component provides the TEE Client API as defined
+	by the <a href="https://www.globalplatform.org/specificationsdevice.asp">GlobalPlatform
+	TEE standard</a>. It is distributed under the BSD 2-clause open-source license.
+-	The optee_os git, containing the source code for the TEE OS itself. This
+	component provides the TEE Internal APIs as defined by the
+	GlobalPlatform  TEE standard to the Trusted Applications that it
+	executes. It is distributed mostly under the BSD 2-clause open-source
+	license. It includes few external files under BSD 3-clause license or
+	other free software licenses.
+-	The optee_linuxdriver git, containing the source code for the TEE driver
+	in Linux. This component implements a generic TEE driver, designed
+	primarily for TEE implementations that rely on the ARM
+	TrustZone(R)technology. It is distributed under the GPLv2 open-source
+	license. Please note that re-distribution under other versions of the
+	GPL license is not allowed. The rationale behind this limitation is to
+	ensure that this code may be used on products which have security
+	devices which prevent reloading the code. Such security devices would be
+	incompatible with some licenses such as GPLv3 and so distribution under
+	those licenses would be inconsistent with this goal. Therefore it is
+	recommended that care be taken before redistributing any of the
+	components under other license terms than those provided here.
