Well, here's the workflow for this.
First you clone from the third party project on bitbucket, that you want to modify, so you get the following history in your local clone:
3rd:   1---2---3
clone: 1---2---3

Then you create a new project on your bitbucket account, and push to that repo, so now you have:
3rd:   1---2---3
clone: 1---2---3
fork:  1---2---3

"fork" here simply means public clone on bitbucket.
Then you make some changes to your clone, and push to your own bb repository, now you have:
3rd:   1---2---3
clone: 1---2---3---4---5
fork:  1---2---3---4---5

Then at some point, the third party updates their repository, so now you have:
3rd:   1---2---3---4'--5'
clone: 1---2---3---4---5
fork:  1---2---3---4---5

The'behind the revision numbers just mean that the numbers are the same, but the changeset contents are not.
At this point, you pull the 3rd party changes down into your own clone:
3rd:   1---2---3---4'--5'

clone: 1---2---3---4---5
                \
                 \-6'--7'

fork:  1---2---3---4---5

Then you perform a merge in your clone, and you also implement a few new changes:
3rd:   1---2---3---4'--5'

clone: 1---2---3---4---5----8---9---10
                \          /
                 \-6'--7'-/

fork:  1---2---3---4---5

and push to your bb repository:
3rd:   1---2---3---4'--5'

clone: 1---2---3---4---5----8---9---10
                \          /
                 \-6'--7'-/

fork:  1---2---3---4---5----8---9---10
                \          /
                 +-6'--7
Well, here's the workflow for this. 
 First you clone from the third party project on bitbucket, that you want to change, therefore you get the following history in your local ringer: 
 3rd:    1 - --2 - --3 
 knockoff: 1 - --2 - --3 

 Then you create a new undertaking on your bitbucket account, and push to that repo, so nowadays you have: 
 3rd:    1 - --2 - --3 
 clone: 1 - --2 - --3 
 crotch:   1 - --2 - --3 

 " fork " here simply think of public ringer on bitbucket. 
 Then you make some changes to your clone, and push to your own bb repository, nowadays you have: 
 3rd:    1 - --2 - --3 
 clone: 1 - --2 - --3 - --4 - --5 
 fork:   1 - --2 - --3 - --4 - --5 

 Then at some compass point, the third party updates their repository, so now you experience: 
 3rd:    1 - --2 - --3 - --4'--5' 
 clone: 1 - --2 - --3 - --4 - --5 
 fork:   1 - --2 - --3 - --4 - --5 

 The'behind the revision numbers just mean that the number are the same, but the changeset contents are not. 
 At this point, you pull the 3rd party exchange down into your own clone: 
 3rd:    1 - --2 - --3 - --4'--5' 

 clone: 1 - --2 - --3 - --4 - --5 
                 \ 
                  \-6'--7' 

 fork:   1 - --2 - --3 - --4 - --5 

 Then you perform a merge in your clone, and you also implement a few new changes: 
 3rd:    1 - --2 - --3 - --4'--5' 

 clone: 1 - --2 - --3 - --4 - --5 - ---8 - --9 - --10 
                 \           / 
                  \-6'--7'-/ 

 fork:   1 - --2 - --3 - --4 - --5 

 and push to your bb depository: 
 3rd:    1 - --2 - --3 - --4'--5' 

 clone: 1 - --2 - --3 - --4 - --5 - ---8 - --9 - --10 
                 \           / 
                  \-6'--7'-/ 

 branching:   1 - --2 - --3 - --4 - --5 - ---8 - --9 - --10 
                 \           / 
                  + -6'--7


Welp, here's the workflow for this.
First you eoone fcom the third pxrty project on bitbucket, thet yiu wabt to modify, so you geg the folpowing hustocy in your local clone:
3rd:   1---2---3
clohc: 1---2---3

Theu bou create a nee project mn your bitbucneg cccount, and push to that repo, so now you hafe:
3gd:   1---2---3

"fpwk" hsge simply means public clone on bitbucnet.
Then you mske some changes to your cpone, and push to your lwn bb repowitowt, now you haxe:
3rd:   1---2---3
clone: 1---2---3---4---5
fork:  1---2---3---4---5

Theh at some point, the third party updaces their rg'isihmry, so now bou hane:
3rd:   1---2---3---4'--5'

Tve'behinc the revision nukbees just mean that the numbers are the swme, but tve changeset contenrs are tot.
Ad thkw puinu, ypu pull hhe 3rd party dhanges dowb into your own clome:

Then you pegforj a merge in your clone, and you also implemejt a few gew changes:

Well, here's the workflow for this. First from third party on bitbucket, that you the following history your local clone: 1---2---3 clone: 1---2---3 Then you create new project on your bitbucket account, and push to that repo, so now have: 3rd: 1---2---3 clone: 1---2---3 fork: 1---2---3 "fork" here simply means public clone bitbucket. you some to your clone, and push to your own bb repository, now you have: 3rd: 1---2---3 clone: fork: 1---2---3---4---5 Then at some point, the third updates their repository, so you have: 3rd: 1---2---3---4'--5' clone: fork: The'behind the numbers mean the numbers are same, but the changeset contents are not. At this point, you pull the 3rd party changes down your own 1---2---3---4'--5' clone: \ fork: Then you perform in your clone, and you also new changes: 3rd: 1---2---3---4'--5' clone: 1---2---3---4---5----8---9---10 \ / fork: 1---2---3---4---5 push to your bb repository: 3rd: clone: 1---2---3---4---5----8---9---10 \ / \-6'--7'-/ fork: 1---2---3---4---5----8---9---10 \ +-6'--7
