The four stages of sedimentary rock origins are weathering, transportation, deposition, and compaction/cementation. Sedimentary rocks are formed from other parts of rocks and after going through the four stages form a sedimentary rock.
The first phase is weathering, which is when the rocks are exposed to elements in the atmosphere. Then more specifically it is either chemically or mechanically weathered. When a rock is chemically weathered it is broken down by some type of chemical reaction and can go through processes such as oxidation, hydrolysis, or carbonation. When a rock is mechanically weathered it does not go through a chemical change, but rather is physically broken apart such as built up pressure from the earth's movement. These rock parts become the basis for the journey the sediments are about to embark in order to form a sedimentary rock.
The next phase is transportation, because after being broken the parts must then travel to become a larger rock. They can be transported by many elements such as water or wind. Larger particles take larger amounts of energy to be transported.
The next phase is deposition. This is the end of their transportation for the most part, when the momentum becomes too low to continue transporting and is thus deposited. After it is transported it begins to form the characteristics of the rock by adapting to the location's attributes chemically, biologically, and physically. They gain these attributes in their final formation.
The last step is compaction and cementation. The layers of the newly forming parts of the rocks begin to come together to form the sedimentary rock. They become bonded together by the pressure from each of the particles, which releases moisture from the compaction to cement them together. This then forms a sedimentary rock.

Four steps to Sedimentary Rocks formation are;
1. Deposition.
2. Compaction.
3. Cementing.
4. Lithification.

The first step in making sedimentary rock is the sediment is produced by the weathering of minerals and large rocks. Then, the sediment is carried by fast-moving water.
Water chemically and mechanically weathers sedimentary rocks. It also weathers and erodes all rock types, transporting and depositing the sediments, a step in the formation of sedimentary rock.
Sedimentary rocks are formed from chemical and physical weathering of rock, their subsequent erosion and transportation to a place of deposit, and their lithification through compaction and cementation.
The second step of the rock cycle is crystallization; the process where liquid rock cools to become minerals/crystals.
Fossils are not formed from sedimentary rock, but within it. An organism that is deposited in sediments after death is covered by additional sediments that protect it from predation and decay. Over time, mineral rich water percolating through hard organic tissue (particularly bone) gradually replaces bone, resulting in lithification (sedimentary rock formation). A record of the organism is thus recorded in the rock--a fossil. A second type of fossil is permineralization, or the infilling of cavities within the dead organism with other material. A third type of fossil is the impression left in soft sedimentary layers (particularly mud) of a track (foot step) or body--such as a leaf, shell, fish or bird. Igneous rock forms from magma; no chance for fossils to form there. Metamorphic rocks are other rock types that are changed by heat and pressure; their transformation and mineral reorganization causes very few fossils to be found there. Sedimentary rock can be formed from the accumulation of sediments and are often formed near ancient shores, basins, and lake beds. If an organism dies and is covered by sediments before rotting or being eaten by scavengers, it could eventually become part of the sedimentary layer that lithifies (becomes rock).
Compaction is a step in the creation of detrital sedimentary rock, those formed from the lithification of sediments.

The first step is weathering.
Mudstone is the fine grained sedimentary rock that were clays or muds originally.

It's when parts of both igneous and metamorphic rocks are crushed together and then they form sedimentary rocks.
