-asdf is an extendable version manager.
+asdf is an extendable version manager. Read the [ballad](https://github.com/HashNuke/asdf/blob/master/ballad-of-asdf.md)
 
 Add or create a source for any package/language/tool you want. There's a [simple API](#creating-package-sources) for it.

+## Install
+
+Copy-paste the following into command line:
+
+```bash
+git clone https://github.com/HashNuke/asdf.git ~/.asdf
+echo 'export PATH="$HOME/.asdf/bin:$PATH"' >> ~/.bash_profile
+```
+
+**That's all ~! You are ready to use asdf**
+
+It clones the adsf repo and adds `~/.asdf/bin` to `$PATH` in `~/.bash_profile`.
+
+
 ## Manage sources
 
 Sources are how asdf understands how to handle packages.
 
-#### Add a source for a package
 
-```
-asdf source-add <name> <git-url>
-```
+#### Add a package
 
-Say you want to add Erlang. There's a package source for it at <https://github.com/HashNuke/asdf-erlang>.
-
-```
+```bash
+# asdf source-add <name> <git-url>
 asdf source-add erlang https://github.com/HashNuke/asdf-erlang.git
 ```
 
 #### Remove a source
 
-```
-asdf source-remove <name>
-```
-
-Now you want to remove the package source for erlang you added earlier.
-
-```
+```bash
+# asdf source-remove <name>
 asdf source-remove erlang
 ```
 
+
 #### Update sources
 
-To update all sources run the following
-
-```
+```bash
+# To update all sources
 asdf source-update --all
 ```
 
 If you want to update a specific package, just say so.
 
-```
-asdf source-update <name>
+```bash
+# asdf source-update <name>
+asdf source-update erlang
 ```
 
 ## Manage packages
 
-```
+```bash
 # asdf install <name> <version>
 asdf install erlang 17.3

+# Ballad of asdf
+
+> Once upon a time there was a programming language  
+There were many versions of it  
+So people wrote a version manager for it  
+To switch between versions for projects  
+Different, old, new.  
+
+> Then there came more programming languages  
+So there came more version managers  
+And many commands for them  
+
+> I installed a lot of them (rbenv, erlenv, exenv, nvm, etc)  
+I learnt a lot of commands  
+
+> Then I said, just one more version manager  
+Which I will write instead  
+
+> So, there came another version manager  
+**asdf version manager** - <https://github.com/HashNuke/asdf>  
+
+> A version manager so extendable  
+for which anyone can create a plugin  
+To support their favourite language  
+No more installing more version managers  
+Or learning more commands
