-If you create proxies for Nested clips they will be saved in \texttt{\$HOME/Videos} unless you modify that in \texttt{Settings $\rightarrow$ Preferences}, \texttt{Interface tab}, \texttt{Nested Proxy Path}. If you change anything in a Nested clip using the Open EDL feature, you must first delete its old proxy file from disk because it is not updated automatically, and then enable Proxy again so that a new one is created.
+Not all the settings for Proxy are saved in the project: the values of Active Scale and the \textit{Rescaled to project size} are saved but not the \textit{File Format}, \textit{File Type} and all video compression data. A good idea is to record this information in a README file about your project where you make a note of your Proxy settings for that project.
+This is especially important because some Projects may use different Proxy settings and
+if you load a project where the Proxy is set and disabled, it could use a different
+setting because you changed the Proxy settings in a project you were working on before.
+If in that Project its proxy files were not deleted and you want to reuse them to save
+time, unfortunately they will be created again because the proxy settings have changed.
