+### Params File
+In your project root, you can put a params file named `.github_changelog_generator` to override default params:
+
+Example:
+```
+unreleased=false

 ### GitHub token
 
-Since GitHub allow to make only 50 requests without authentication it's recommended to run this script with token
+GitHub only allows only 50 unauthenticated requests per hour. 
+Therefore, it's recommended to run this script with authentication by using a **token**.
 
-**You can easily [generate it here](https://github.com/settings/applications)**.
+Here's how:
 
-And:
+- [Generate a token here](https://github.com/settings/tokens/new?description=GitHub%20Changelog%20Generator%20token)
+- Either:
+    - Run the script with `--token <your-40-digit-token>`; **OR**
+    - Set the `CHANGELOG_GITHUB_TOKEN` environment variable to your 40 digit token
 
-- Run with key `-t [your-16-digit-token]` 
-- Or set environment variable `CHANGELOG_GITHUB_TOKEN` and specify there your token. 
+You can set an environment variable by running the following command at the prompt, or by adding it to your shell profile (e.g., `~/.bash_profile` or `~/.zshrc`):
 
-	i.e. add to your `~/.bash_profile` or `~/.zshrc` or any other place to load ENV variables string :
+        export CHANGELOG_GITHUB_TOKEN="«your-40-digit-github-token»"
 
-        export CHANGELOG_GITHUB_TOKEN="your-40-digit-github-token"
-
-So, if you got error like this:
+So, if you got an error like this:
 >! /Library/Ruby/Gems/2.0.0/gems/github_api-0.12.2/lib/github_api/response/raise_error.rb:14:in `on_complete'
 
-It's time to create this token or wait for 1 hour before GitHub reset the counter for your IP.
+It's time to create this token! (Or, wait an hour for GitHub to reset your unauthenticated request limit.)
+
+## Migrating from a manual changelog
+
+Knowing how dedicated you are to your project, you probably haven't been waiting for `github-changelog-generator` to keep a changelog.
+But you probably don't want your project's open issues and PRs for all past features listed in your historic changelog, either.
+
+That's where `--base <your-manual-changelog.md>` comes in handy!
+This option lets append your old manual changelog to the end of the generated entries.
+
+If you have a `HISTORY.md` file in your project, it will automatically be picked as the static historical changelog and appended.
+
+### Rake task
+
+You love `rake`? We do, too! So, we've made it even easier for you: 
+we've provided a `rake` task library for your changelog generation.
+
+Just put something like this in your `Rakefile`:
+
+```ruby
+GitHubChangelogGenerator::RakeTask.new :changelog do |config|
+  config.since_tag = '0.1.14'
+  config.future_release = '0.2.0'
+end
+```
+
+All command line options can be passed to the `rake` task as `config` parameters. And since you're naming the `rake` task yourself, you can create as many as you want.

+
+## FAQ
+
+- ***I already use GitHub Releases. Why do I need this?***
+
+GitHub Releases is a very good thing. And it's very good practice to maintain it. (Not a lot of people are using it yet!) :congratulations:
+
+*BTW: I would like to support GitHub Releases in [next releases](https://github.com/skywinder/github-changelog-generator/issues/56) ;)*
+
+I'm not trying to compare the quality of handwritten and auto-generated logs. That said....
+
+An auto-generated changelog really helps, even if you manually fill in the release notes!
+
+For example:
+
+When I found a closed bug, it's very useful know which release fixed it. 
+In this case, you can easily find the issue by \# in `CHANGELOG.md`.
+
+- it's not quite as easy to find this in handwritten releases notes
+- a generated file saves you the trouble of remembering everything;
+  sometimes people forget to add things to a handwritten file
+
+Ultimately, I think GitHub Releases is ideal for end-users. 
+Meanwhile, `CHANGELOG.md` lives right in the repository, with its detailed list of changes, which is handy for developers.
+Finally, there's nothing wrong with using GitHub Releases alongside `CHANGELOG.md` in this combination.
+
+- ***I received a warning: "GitHub API rate limit exceed"  What does this mean?***
+
+GitHub [limits the number of API requests](https://developer.github.com/v3/#rate-limiting) you can make in an hour. You can make up to 5,000 requests per hour. For unauthenticated requests, the rate limit is only up to 60 requests per hour. Unauthenticated requests are associated with your IP address (not the user making requests).
+
+If you're seeing this warning, please do the following:
+
+1. Make sure you're providing an OAuth token, so you're not making requests anonymously. Using an OAuth token increases your hourly request maximum from 60 to 5000.
+2. If you have a large repo with lots of issues/PRs, you can use `--max-issues NUM` to limit the number of issues that are pulled back. For example: `--max-issues 1000`
 
 ## Contributing
