+# Share Extension Creation Instructions
+## Creating the Target
+2. In Xcode select File->New->Target
+3. Then search for Share Extension
+4. Select Share Extension and click Next
+5. In Product Name enter ShareExtension
+6. Leave the rest of the options and click Finish
+7. If the Activate "ShareExtension" scheme popup comes, click Activate
+
+## Configuring the Share Extension
+1. Delete *ShareViewController.h* and *ShareViewController.m* from the project. (Select files and right click, then Delete)
+2. On the confirmation popup, select Move to Trash
+3. Now add *ShareViewController.h* and *ShareViewController.m* from *ShareExtension/Source/ShareExtension*. This can be done by right clicking on the *ShareExtension* folder in Xcode and selecting Add Files to "Joplin". Double check that the ShareExtension is checked for Add to targets and click Add.
+4. Switch over to git and reset the changes done to *ShareExtension/Base.lproj/Maininterface.storyboard* and *ShareExtension/Info.plist*, as Xcode generated new versions of these files and overwrote ours.
+5. Now select the ShareExtension Target and go to Signing & Capabilities
+6. Click the + Capability and search for App Groups and add it
+7. Back in git reset *ShareExtension/ShareExtension.entitlements* as Xcode just overwrote it. Back in Xcode you should see the app group set
+8. Now switch to General, just left of Signing & Capabilities
+9. Under Deployment Info, change the iOS version to match the Joplin target version, which is 9.0
+
+## Configuring Joplin
+1. We need to perform the same steps to add the App Group as done for the Share Extension, the only difference is the entitlements files is *Joplin.entitlements*
+
+## Final Steps
+1. Run pod install from the ios directory to install the new pods
+
+# Other Information
+## App Group
+If the app group name needs to be changed for some reason, it needs to be changed for both the Share Extension and Joplin. Also *ShareExtensionGroupIdentifier* in *ShareExtension/Source/Common/ShareExtensionConstants.m* needs to be changed to match the new app group.
