 ## Install
 * Prepare a server, set its timezone to the users' timezone
-  (on deb-based systems: `dpkg-reconfigure tzdata`)
-* On the server, `cd` to the place where you want the files
-* Clone repo: `git clone https://gitlab.com/pepa65/streamupload`
-* `cd streamupload`
-* Change the value of the `repopath` variable in `stream` and `encode`
-  to the output of `echo $PWD`
-* Run a php/webserver on $PWD/uploadpage
-  - Get it to restart on reboot

+* Clone repo: `git clone https://gitlab.com/pepa65/streamupload`.
+* `cd streamupload`.
+* Run a php/webserver on $PWD/uploadpage:
+  - Get it to restart on reboot.
   - Setting up basicauth on the page is a good idea if others can get access!
   - Change the relevant `php.ini` to allow large file uploads:
-    * `post_max_size` - Upper limit of uploaded video sizes, say `10G`
-    * `upload_max_filesize` - same value as `post_max_size`
-* Make a crontab-entry: "* * * * *  $PWD/encode" (replace $PWD with its value!)
+    * `post_max_size` - Upper limit of uploaded video sizes, say `10G`.
+    * `upload_max_filesize` - same value as `post_max_size`.
+* Make a crontab-entry: "* * * * *  $PWD/encode" (replace $PWD with its value!).
+* Install the `mailer` binary by downloading it from the repo at
+  https://https://github.com/pepa65/mailer/releases/latest and moving it to
+  `/usr/local/bin` and make it executable: `chmod +x /usr/local/bin/mailer`.
+  If it's not installed, everything except the email will still work.
+* Copy `_mailvars` to `mailvars` and set the variables
+  `to`, `user`, `password`, `smtp` and `port` in it in order to
+  receive mail notifications when the encodes are finished.
 
 ## Usage
 * Get a streamkey for the target by scheduling a stream
