+Avatar Local File Example
+====
+
+This example demonstrates how to utilize DiscordGo to change the account avatar using a local file inside the current working directory.
+
+### Build
+
+This assumes you already have a working Go environment setup and that DiscordGo is correctly installed on your system.
+Change directory into the example.
+
+```sh
+cd $GOPATH/src/github.com/bwmarrin/discordgo/examples/avatar/localfile
+```
+
+```sh
+go build
+```
+
+### Usage
+
+Please place the file you wish to use as an avatar inside the directory named as ``avatar.jpg``. The filename is not important if you supply it via the commandline flag ``-f`` when starting the application.
+
+```sh
+./localfile --help
+Usage of ./ocalfile:
+  -e string
+        Account Email
+  -p string
+        Account Password
+  -t string
+        Account Token
+  -f string
+  		Avatar File Name.
+```
+
+For example to start application with Token and a non-default avatar:
+
+```sh
+./localfile -t "YOUR_BOT_TOKEN" -f "./pathtoavatar.jpg"
+```

+Avatar Url Example
+====
+
+This example demonstrates how to utilize DiscordGo to change the account avatar using a remote url provided via a commandline flag.
+
+### Build
+
+This assumes you already have a working Go environment setup and that DiscordGo is correctly installed on your system.
+Change directory into the example.
+
+```sh
+cd $GOPATH/src/github.com/bwmarrin/discordgo/examples/avatar/url
+```
+
+```sh
+go build
+```
+
+### Usage
+
+Please place the file you wish to use as an avatar inside the directory named as ``avatar.jpg``. The filename is not important if you supply it via the commandline flag ``-l`` when starting the application. If the flag is not specified avatar is set to DiscordGo Logo.
+
+```sh
+./url --help
+Usage of ./url:
+  -e string
+        Account Email
+  -p string
+        Account Password
+  -t string
+        Account Token
+  -l string
+  		Link to the avatar image.
+```
+
+For example to start application with Token and a non-default avatar:
+
+```sh
+./url -t "YOUR_BOT_TOKEN" -l "http://bwmarrin.github.io/discordgo/img/discordgo.png"
+```
