+# Contributing
+
+Thank you for considering to help out with the source code! We welcome 
+contributions from anyone on the internet, and are grateful for even the 
+smallest of fixes!
+
+If you'd like to contribute to go-ethereum, please fork, fix, commit and send a 
+pull request for the maintainers to review and merge into the main code base. If
+you wish to submit more complex changes though, please check up with the core 
+devs first on [our gitter channel](https://gitter.im/ethereum/go-ethereum) to 
+ensure those changes are in line with the general philosophy of the project 
+and/or get some early feedback which can make both your efforts much lighter as
+well as our review and merge procedures quick and simple.
+
+## Coding guidelines
+
+Please make sure your contributions adhere to our coding guidelines:
+
+ * Code must adhere to the official Go 
+[formatting](https://golang.org/doc/effective_go.html#formatting) guidelines 
+(i.e. uses [gofmt](https://golang.org/cmd/gofmt/)).
+ * Code must be documented adhering to the official Go 
+[commentary](https://golang.org/doc/effective_go.html#commentary) guidelines.
+ * Pull requests need to be based on and opened against the `master` branch.
+ * Commit messages should be prefixed with the package(s) they modify.
+   * E.g. "eth, rpc: make trace configs optional"
+
 ## Can I have feature X
 
-Before you do a feature request please check and make sure that it isn't possible
-through some other means. The JavaScript enabled console is a powerful feature
-in the right hands. Please check our [Wiki page](https://github.com/ethereum/go-ethereum/wiki) for more info

 ### Changelog for external API
 
+#### 4.0.0
 
+* The external `account_Ecrecover`-method was removed. 
+* The external `account_Import`-method was removed.

+#### 3.0.0
+
+* The external `account_List`-method was changed to not expose `url`, which contained info about the local filesystem. It now returns only a list of addresses.

 ### Changelog for internal API (ui-api)
 
+### 3.0.0
+
+* Make use of `OnInputRequired(info UserInputRequest)` for obtaining master password during startup
+
+### 2.1.0
+
+* Add `OnInputRequired(info UserInputRequest)` to internal API. This method is used when Clef needs user input, e.g. passwords.
+
+The following structures are used:
+```golang
+       UserInputRequest struct {
+               Prompt     string `json:"prompt"`
+               Title      string `json:"title"`
+               IsPassword bool   `json:"isPassword"`
+       }
+       UserInputResponse struct {
+               Text string `json:"text"`
+       }
+
 ### 2.0.0
 
 * Modify how `call_info` on a transaction is conveyed. New format:
