+The basic structure of the file is as follows:

+typeName:
+  desc: A brief description of the type.
+  req:
+    field1: A brief description of field1.
+    field2: A brief description of field2.
+    field3: A brief description of field3.
+  opt:
+    field1: A brief description of field1.
+    field2: A brief description of field2.
+    field3: A brief description of field3.
+```
+
+For example:
+```yaml
+article:
+  desc: An article in a journal, magazine, newspaper, or other periodical which forms a self-contained unit with its own title.
+  req:

+
+To load the entry types to be used by Scholar, do:
+
+```go
+func main() {
+    if err := scholar.LoadTypes("types.yaml"); err != nil {
+        // handle error
+    }    
+}
+```
+
+To create a new Entry struct, do:
+```go
+    entry := scholar.NewEntry("article")
+```
+
+To change the type of an entry, do:
+```go
+    entryArticle := scholar.NewEntry("article")
+    entryBook := scholar.Convert(entryArticle, "book")
+```
+
+To get a BibLaTex format reference, do:
+```go
+    entry := scholar.NewEntry("article")
+    entry.Required["title"] = "The Article"
+    entry.Required["author'] = "Last, First and Other, Second"
+    entry.Required["journaltitle"] = "The Journal of Articles"
+    entry.Required["date"] = "2018"
+
+    fmt.Println(entry.Bib())
 ```
-go get github.com/cgxeiji/scholar/scholar
 ```
+output:
+    @article{last2018,
+      author = {Last, First and Other, Second},
+      date = {2018},
+      journaltitle = {The Journal of Articles},
+      title = {The Article}
+    }
+```
