The English Football League Championship is the second division league of the English Football League system after the Premier League which is the highest level league in the whole of England. English Football League Championship is commonly known as Championship and for sponsorship purposes, Sky Bet Championship. Currently, it features 24 Clubs only.
The English Football League Championship was introduced in the 2004-05 season. It is a rebrand of the former Football League First Division which is itself a rebrand of Football League Second division. It all existed before the Premier League came into picture in 1992. But as soon as it was launched, the game was reversed and the Premier League became the highest level (First Division) league in England. 
Who gets promoted from the English Championship?
As of now, every division or league has scope of promotion except for the Premier League. The top performing clubs from every division are promoted to upper divisions or Cup competitions. Same thing goes with the English Championship. The two top performing clubs of the second highest league are automatically promoted to Premier League which is considered the boss of all.
Also, the teams which finish the season in 3rd through 6th place compete in the playoff tournament. And whoever club becomes the winner receives the promotion to Premier League as well. So, in total three clubs get promoted from the English Football League Championship.
You should know that not only clubs get promoted from but to the English Championship as well. Though the term used for it is different, it is the same as this. The worst performing clubs of the Premier League get relegated to the English Championship.

Also, it is ninth richest division in Europe while tenth best attended division in the world given its attendance in the average match for 2018-19 season was 20,181.

Third and Fourth Division
Its time to take a glimpse inside League 1 and League 2 which are the third and fourth levels of this system respectively. Both of these leagues function quite similarly.
Unlike the Premier League, both these leagues have scope of promotion. The top three teams in both leagues are promoted to higher level divisions. Teams that finished fourth to seventh place in the league are promoted to the playoffs tournament. Whichever team wins in the playoffs will be the fourth team to get promotion. So, in total four promotion slots are available in these sister leagues.
While talking about relegation, there is some variation in the method. The four worst performing teams in League 1 are relegated to League 2. And in League 2, the four worst performing teams are excluded to the Fifth division.
