+# NAME
+
+finbudg - Quick cli tool to calculate your expenses and balance for a set period
+of time.
+
+# DESCRIPTION
+
+This manual page documents the syntax of the expenses files used by the
+*finbudg* program.
+
+# SYNTAX
+
+Expenses files used by *finbudg* use the toml file format as their base for the
+syntax.
+
+## PREAMBLE
+
+The expenses file should contain at the start the following keys:
+
+*start_date*=YYYY-MM-DD
+	This is the date when the period for this budget starts, e.g. your payday.
+
+*end_date*=YYYY-MM-DD
+	This is the date when the period for this budget ends, e.g. the day before
+	your next payday.
+
+*budget*=float64
+	A floating point number that represents your budget for the specified period
+	of time.
+
+*essential_categories*=String[]
+	An array of strings representing the categories that you want to take into
+	account as "essential". _Optional_.
+
+*[[days]]*
+	An entry of this type is an entry for the array of tables *days* and
+	contains the following keys:
+
+		*date*=YYYY-MM-DD
+			The date for this day when the following expenses were made.
+
+		*[[days.expenses]]*
+			An entry of this type is an entry for the nested array of tables
+			*expenses* inside of an entry of type *days*. It may contain the
+			following keys:
+
+				*name*=String
+					The name of the product/service/etc. that money was spent
+					on.
+
+				*price*=float64
+					How much money was spent on said product/service/etc.
+
+				*category*=String
+					The category to which this expense belongs. _Optional_.
+
+				*shared*=uint32
+					If more than one, then the amount of people this expense was
+					shared with. _Optional_.
+
+				*recurring*=bool
+					Indicates if this is a recurring expense, i.e. one that
+					repeats for each period of time. For example, electricity
+					bills. _Optional_.
+
+# NOTES
+
+The dates should be in ISO 8601 format with *NO* time in them, e.g.
+*2020-04-20*.
+
+You don't have to include every day in the period in your expenses file if you
+didn't spend any money that day. The program will take into account the last
+date in the file to count the number of days. Also, the *[[days.expenses]]* key
+is optional, you can also include a day and omit the expenses.
+
+If you're not very familiar with the TOML format, you should take a look at
+*https://toml.io/en/v1.0.0-rc.2*. Especially the part about arrays of tables.
+
+If you're still not sure how the input file should look like, or if you prefer
+to learn by example, take a look at *https://github.com/Yaroslav-95/finbudg*.
+The README.md includes an example of an expense file.
