+PlutoSDR Firmware for the [ADALM-PLUTO](https://wiki.analog.com/university/tools/pluto "PlutoSDR Wiki Page") Active Learning Module
+
+The ADALM-PLUTO SDR firmware is a collection of components, computer programs and documents created by a range of individuals, 
+teams and companies. Most of the components are open source packages, developed independently, and accompanied by separate 
+license terms (such as GPL, LGPL, BSD, MIT, Apache, modified BSD or others). Your license rights with respect to individual components
+accompanied by separate license terms are defined by those terms (The license agreement for each component is generally 
+located in the component's source code); nothing shall restrict, limit, or otherwise affect any rights or obligations you may
+have, or conditions to which you may be subject, under such license terms. This agreement does not limit your rights under, 
+or grant you rights that supersede, the license terms of any particular component.
+
+With the potential exception of certain firmware files, the license terms of components normally included in the 
+ADALM-PLUTO SDR firmware normally permit you to copy, modify, and redistribute the component, in both source code
+and binary code forms.
+
+You are free to re-use any indivual or multiple components in an end product that you create, but it is up to you and 
+your legal team to make sure your product complies with the licensing requirements of whatever software package that 
+you include in your product.
+
+You may make and use unlimited copies of the ADALM-PLUTO SDR firmware for your distribution and use within your organization. 
+You may make and distribute unlimited copies of the ADALM-PLUTO SDR firmware outside your organization.
+
+# NO WARRANTY
+
+BECAUSE THE ADALM-PLUTO SDR FIRMWARE IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED
+BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS”
+WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY
+AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY 
+MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, 
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO 
+LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO 
+OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
